LibSBML uses the class SBMLDocument as a top-level container for storing SBML content and data associated with it (such as warnings and error messages). The two primary means of reading an SBML model, SBMLReader.readSBML() and SBMLReader.readSBMLFromString(), both return a pointer to an SBMLDocument object. From there, callers can inquire about any errors encountered (e.g., using SBMLDocument.getNumErrors()), access the Model object, and perform other actions such as consistency-checking and model translation.
When creating fresh models programmatically, the starting point is typically the creation of an SBMLDocument object instance. The SBMLDocument constructor accepts arguments for the SBML Level and Version of the model to be created. After creating the SBMLDocument object, calling programs then typically call SBMLDocument.createModel() almost immediately, and then proceed to call the methods on the Model object to fill out the model's contents.
SBMLDocument corresponds roughly to the class Sbml defined in the SBML Level 2 specification and SBML in the Level 3 specification. It does not have a direct correspondence in SBML Level 1. (However, to make matters simpler for applications, libSBML creates an SBMLDocument no matter whether the model is Level 1, Level 2 or Level 3.) In its barest form, when written out in XML format for (e.g.) SBML Level 2 Version 4, the corresponding structure is the following:
<sbml xmlns='http://www.sbml.org/sbml/level2/version4' level='2' version='4'> ... </sbml>
SBMLDocument is derived from SBase, and therefore contains the usual SBase attributes (in SBML Level 2 and Level 3) of 'metaid' and 'sboTerm', as well as the subelements 'notes' and 'annotation'. It also contains the attributes 'level' and 'version' indicating the Level and Version of the SBML data structure. These can be accessed using the methods defined by the SBase class for that purpose.
One of the most important features of libSBML is its ability to perform SBML validation to ensure that a model adheres to the SBML specification for whatever Level+Version combination the model uses. SBMLDocument provides the methods for running consistency-checking and validation rules on the SBML content.
First, a brief explanation of the rationale is in order. In libSBML versions up to and including the version 3.3.x series, the individual methods for creating and setting attributes and other components were quite lenient, and allowed a caller to compose SBML entities that might not, in the end, represent valid SBML. This allowed applications the freedom to do things such as save incomplete models (which is useful when models are being developed over long periods of time). In the version 4.x series, libSBML is somewhat stricter, but still permits structures to be created independently and the results to be combined in a separate step. In all these cases, it means that a separate validation step is necessary when a calling program finally wants to finish a complete SBML document.
The primary interface to this validation facility is SBMLDocument's SBMLDocument.checkInternalConsistency() and SBMLDocument.checkConsistency(). The former verifies the basic internal consistency and syntax of an SBML document, and the latter implements more elaborate validation rules (both those defined by the SBML specifications, as well as additional rules offered by libSBML).
The checks performed by SBMLDocument.checkInternalConsistency() are hardwired and cannot be changed by calling programs, but the validation performed by SBMLDocument.checkConsistency() is under program control using the method SBMLDocument.setConsistencyChecks(). Applications can selectively disable specific kinds of checks that they may not be interested in, by calling SBMLDocument.setConsistencyChecks() with appropriate parameters.
These methods have slightly different relevance depending on whether a model is created programmaticaly from scratch, or whether it is read in from a file or data stream. The following list summarizes the possible scenarios.
Scenario 1: Creating a model from scratch. Before writing out the model,
Scenario 2: Reading a model from a file or data stream. After reading the model,
It should be noted that as of SBML Level 3 Version 2, the Model became an optional child of SBMLDocument, instead of being required. This means that one can no longer use SBMLDocument.getModel() as a cheap method of checking if an SBML document was read in properly: the more robust getError methods detailed above must be used instead.
LibSBML provides facilities for limited translation of SBML between Levels and Versions of the SBML specifications. The method for doing is is setLevelAndVersion() . In general, models can be converted upward without difficulty (e.g., from SBML Level 1 to Level 2, or from an earlier Version of Level 2 to the latest Version of Level 2). Sometimes models can be translated downward as well, if they do not use constructs specific to more advanced Levels of SBML.
Calling SBMLDocument.setLevelAndVersion() will not necessarily lead to a successful conversion. The method will return a boolean value to indicate success or failure. Callers must check the error log (see next section) attached to the SBMLDocument object after calling SBMLDocument.setLevelAndVersion() in order to assess whether any problems arose.
If an application is interested in translating to a lower Level and/or Version of SBML within a Level, the following methods allow for prior assessment of whether there is sufficient compatibility to make a translation possible:
Some changes between Versions of SBML Level 2 may lead to unexpected behaviors when attempting conversions in either direction. For example, SBML Level 2 Version 4 relaxed the requirement for consistency in units of measurement between expressions annd quantities in a model. As a result, a model written in Version 4, if converted to Version 3 with no other changes, may fail validation as a Version 3 model because Version 3 imposed stricter requirements on unit consistency.
Other changes between SBML Level 2 and Level 3 make downward conversions challenging. In some cases, it means that a model converted to Level 2 from Level 3 will contain attributes that were not explicitly given in the Level 3 model, because in Level 2 these attributes may have been optional or have default values.
Upon reading a model, SBMLDocument logs any problems encountered while reading the model from the file or data stream. The log contains objects that record diagnostic information about any notable issues that arose. Whether the problems are warnings or errors, they are both reported through a single common interface involving the object class SBMLError.
The methods SBMLDocument.getNumErrors(), SBMLDocument.getError() and SBMLDocument.printErrors() allow callers to interact with the warnings or errors logged. Alternatively, callers may retrieve the entire log as an SBMLErrorLog object using the method SBMLDocument.getErrorLog(). The SBMLErrorLog object provides some alternative methods for interacting with the set of errors and warnings. In either case, applications typically should first call SBMLDocument.getNumErrors() to find out if any issues have been logged after specific libSBML operations such as the ones discussed in the sections above. If they have, then an application will should proceed to inspect the individual reports using either the direct interfaces on SBMLDocument or using the methods on the SBMLErrorLog object.

Creates a new SBMLDocument using the given SBMLNamespaces object sbmlns.
| sbmlns | an SBMLNamespaces object. |
| ValueError | Thrown if the given sbmlns is inconsistent or incompatible with this object. |
SBMLDocument(long level = 0, long version = 0)
Creates a new SBMLDocument, optionally with given values for the SBML Level and Version.
If both the SBML Level and Version attributes are not specified, the SBML document is treated as having the latest Level and Version of SBML as determined by SBMLDocument.getDefaultLevel() and SBMLDocument.getDefaultVersion(); however, the SBMLDocument object is otherwise left blank. In particular, the blank SBMLDocument object has no associated XML attributes, including (but not limited to) an XML namespace declaration. The XML namespace declaration is not added until the model is written out, or the method SBMLDocument.setLevelAndVersion() is called. This may be important to keep in mind if an application needs to add additional XML namespace declarations on the <sbml> element. Application writers should either provide values for level and version on the call to this constructor, or else call SBMLDocument.setLevelAndVersion() shortly after creating the SBMLDocument object.

This method has multiple variants; they differ in the arguments they accept.
appendAnnotation(XMLNode annotation) int appendAnnotation(string annotation) int
Each variant is described separately below.
appendAnnotation(XMLNode annotation)
Appends the given annotation to the 'annotation' subelement of this object.
Whereas the SBase 'notes' subelement is a container for content to be shown directly to humans, the 'annotation' element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for 'annotation'. The element's content type is XML type 'any', allowing essentially arbitrary well-formed XML data content.
SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.
Unlike SBase.setAnnotation() or SBase.setAnnotation(), this method allows other annotations to be preserved when an application adds its own data.

appendNotes(XMLNode notes) int appendNotes(string notes) int
Each variant is described separately below.
appendNotes(string notes)
Appends the given notes to the 'notes' subelement of this object.
The content of the parameter notes is copied.
The optional SBML element named 'notes', present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the 'notes' element would be to contain formatted user comments about the model element in which the 'notes' element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for 'notes', allowing users considerable freedom when adding comments to their models.
The format of 'notes' elements must be XHTML 1.0.

Disables the given SBML Level 3 package on this object.
disablePackage(string pkgURI, string pkgPrefix) intThis method disables the specified package on this object and other objects connected by child-parent links in the same SBMLDocument object.
An example of when this may be useful is during construction of model components when mixing existing and new models. Suppose your application read an SBML document containing a model that used the SBML Hierarchical Model Composition (“comp”) package, and extracted parts of that model in order to construct a new model in memory. The new, in-memory model will not accept a component drawn from an other SBMLDocument with different package namespace declarations. You could reconstruct the same namespaces in the in-memory model first, but as a shortcut, you could also disable the package namespace on the object being added. Here is a code example to help clarify this:
| pkgURI | the URI of the package. |
| pkgPrefix | the XML prefix of the package. |
| def libsbml.SBMLDocument.enableDefaultNS | ( | self, | |
| package, | |||

| def libsbml.SBMLDocument.expandFunctionDefinitions | ( | self | ) |
Removes FunctionDefinition constructs from the document and expands any instances of their use within <math> elements.
expandFunctionDefinitions() boolFor example, suppose a Model contains a FunctionDefinition with identifier 'f' representing the math expression: f(x, y) = x * y. Suppose further that there is a reaction in which the <math> element of the KineticLaw object contains f(s, p), where s and p are other identifiers defined in the model. The outcome of invoking this method is that the <math> of the KineticLaw now represents the expression s * p and the model no longer contains any FunctionDefinition objects.
True if the transformation was successful, False, otherwise.False. | def libsbml.SBMLDocument.expandInitialAssignments | ( | self | ) |
Removes InitialAssignment constructs from the document and replaces them with appropriate values.
expandInitialAssignments() boolFor example, suppose a Model contains a InitialAssignment to a symbol 'k' where 'k' is the identifier of a Parameter. The outcome of invoking this method is that the 'value' attribute of the Parameter definition is set to the result calculated using the InitialAssignment object's <math> formula, and the corresponding InitialAssignment is then removed from the Model.
True if the transformation was successful, False, otherwise.False. As part of that process, this method will check that it has values for any components referred to by the <math> elements of InitialAssignment objects. In cases where not all of the values have been declared (e.g., if the mathematical expression refers to model entities that have no declared values), the InitialAssignment in question will not be removed and this method will return False.

( and ) are used for grouping, the character * 'zero or more times', and the character | indicates logical 'or'. The equality of SBML identifiers is determined by an exact character sequence match; i.e., comparisons must be performed in a case-sensitive manner. This applies to all uses of SId, SIdRef, and derived types.Users need to be aware of some important API issues that are the result of the history of SBML and libSBML. Prior to SBML Level 3 Version 2, SBML defined 'id' and 'name' attributes on only a subset of SBML objects. To simplify the work of programmers, libSBML's API provided get, set, check, and unset on the SBase object class itself instead of on individual subobject classes. This made the get/set/etc. methods uniformly available on all objects in the libSBML API. LibSBML simply returned empty strings or otherwise did not act when the methods were applied to SBML objects that were not defined by the SBML specification to have 'id' or 'name' attributes. Additional complications arose with the rule and assignment objects: InitialAssignment, EventAssignment, AssignmentRule, and RateRule. In early versions of SBML, the rule object hierarchy was different, and in addition, then as now, they possess different attributes: 'variable' (for the rules and event assignments), 'symbol' (for initial assignments), or neither (for algebraic rules). Prior to SBML Level 3 Version 2, getId() would always return an empty string, and isSetId() would always return False for objects of these classes.
With the addition of 'id' and 'name' attributes on SBase in Level 3 Version 2, it became necessary to introduce a new way to interact with the attributes more consistently in libSBML to avoid breaking backward compatibility in the behavior of the original 'id' methods. For this reason, libSBML provides four functions (getIdAttribute(), setIdAttribute(), isSetIdAttribute(), and unsetIdAttribute()) that always act on the actual 'id' attribute inherited from SBase, regardless of the object's type. These new methods should be used instead of the older getId()/setId()/etc. methods unless the old behavior is somehow necessary. Regardless of the Level and Version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have identifiers). If the object in question does not posess an 'id' attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the identifier to be set, nor will it read or write 'id' attributes for those objects.

Returns the value of the 'metaid' attribute of this SBML object.
getMetaId() stringID, the XML identifier type, which means each 'metaid' value must be globally unique within an SBML file. The latter point is important, because the uniqueness criterion applies across any attribute with type ID anywhere in the file, not just the 'metaid' attribute used by SBML—something to be aware of if your application-specific XML content inside the 'annotation' subelement happens to use the XML ID type. Although SBML itself specifies the use of XML ID only for the 'metaid' attribute, SBML-compatible applications should be careful if they use XML ID's in XML portions of a model that are not defined by SBML, such as in the application-specific content of the 'annotation' subelement. Finally, note that LibSBML does not provide an explicit XML ID data type; it uses ordinary character strings, which is easier for applications to support.

Returns the value of the 'name' attribute of this SBML object.
getName() stringThe 'name' attribute is optional and is not intended to be used for cross-referencing purposes within a model. Its purpose instead is to provide a human-readable label for the component. The data type of 'name' is the type string defined in XML Schema. SBML imposes no restrictions as to the content of 'name' attributes beyond those restrictions defined by the string type in XML Schema.
The recommended practice for handling 'name' is as follows. If a software tool has the capability for displaying the content of 'name' attributes, it should display this content to the user as a component's label instead of the component's 'id'. If the user interface does not have this capability (e.g., because it cannot display or use special characters in symbol names), or if the 'name' attribute is missing on a given component, then the user interface should display the value of the 'id' attribute instead. (Script language interpreters are especially likely to display 'id' instead of 'name'.)
As a consequence of the above, authors of systems that automatically generate the values of 'id' attributes should be aware some systems may display the 'id''s to the user. Authors therefore may wish to take some care to have their software create 'id' values that are: (a) reasonably easy for humans to type and read; and (b) likely to be meaningful, for example by making the 'id' attribute be an abbreviated form of the name attribute value.
An additional point worth mentioning is although there are restrictions on the uniqueness of 'id' values, there are no restrictions on the uniqueness of 'name' values in a model. This allows software applications leeway in assigning component identifiers.
Regardless of the level and version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have names). If the object in question does not posess a 'name' attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the name to be set, nor will it read or write 'name' attributes for those objects.

getPlugin(long n)
Returns the nth plug-in object (extension interface) for an SBML Level 3 package extension. The returned plug-in will be the appropriate type of plugin requested: calling Model.getPlugin() will return an FbcModelPlugin; calling Parameter.getPlugin() will return CompSBasePlugin, etc.

getPrefix() stringThis reports the XML namespace prefix chosen for this class of object in the current SBML document. This may be an empty string if the component has no explicit prefix (for instance, if it is a core SBML object placed in the default SBML namespace of the document). If it is not empty, then it corresponds to the XML namespace prefix used set the object, whatever that may be in a given SBML document.

Returns the MIRIAM biological qualifier associated with the given resource.
getResourceBiologicalQualifier(string resource) longIn MIRIAM, qualifiers are an optional means of indicating the relationship between a model component and its annotations. There are two broad kinds of annotations: model and biological. The latter kind is used to qualify the relationship between a model component and a biological entity which it represents. Examples of relationships include 'is' and 'has part', but many others are possible. MIRIAM defines numerous relationship qualifiers to enable different software tools to qualify biological annotations in the same standardized way. In libSBML, the MIRIAM controlled-vocabulary annotations on an SBML model element are represented using lists of CVTerm objects, and the the MIRIAM biological qualifiers are represented using valueswhose names begin with BQB_ in the interface class libsbml.
This method searches the controlled-vocabulary annotations (i.e., the list of CVTerm objects) on the present object, then out of those that have biological qualifiers, looks for an annotation to the given resource. If such an annotation is found, it returns the type of biological qualifier associated with that resource as a valuewhose name begins with BQB_ from the interface class libsbml.
| resource | string representing the resource; e.g., 'http://www.geneontology.org/#GO:0005892'. |
BQB_ constants defined in libsbml may be expanded in later libSBML releases, to match the values defined by MIRIAM at that later time.

Returns the MIRIAM model qualifier associated with the given resource.
getResourceModelQualifier(string resource) longIn MIRIAM, qualifiers are an optional means of indicating the relationship between a model component and its annotations. There are two broad kinds of annotations: model and biological. The former kind is used to qualify the relationship between a model component and another modeling object. An example qualifier is 'isDerivedFrom', to indicate that a given component of the model is derived from the modeling object represented by the referenced resource. MIRIAM defines numerous relationship qualifiers to enable different software tools to qualify model annotations in the same standardized way. In libSBML, the MIRIAM controlled-vocabulary annotations on an SBML model element are represented using lists of CVTerm objects, and the the MIRIAM model qualifiers are represented using valueswhose names begin with BQM_ in the interface class libsbml.
This method method searches the controlled-vocabulary annotations (i.e., the list of CVTerm objects) on the present object, then out of those that have model qualifiers, looks for an annotation to the given resource.

getTypeCode() intSBML_. In the Python language interface for libSBML, the type codes are defined as static integer constants in the interface class libsbml. Note that different Level 3 package plug-ins may use overlapping type codes; to identify the package to which a given object belongs, call the SBase.getPackageName() method on the object.The exception to this is lists: all SBML-style list elements have the type SBML_LIST_OF, regardless of what package they are from.

Gets the namespace URI to which this element belongs to.
getURI() stringFor example, all elements that belong to SBML Level 3 Version 1 Core must would have the URI 'http://www.sbml.org/sbml/level3/version1/core'; all elements that belong to Layout Extension Version 1 for SBML Level 3 Version 1 Core must would have the URI 'http://www.sbml.org/sbml/level3/version1/layout/version1'.
This function first returns the URI for this element by looking into the SBMLNamespaces object of the document with the its package name. If not found, it will then look for the namespace associated with the element itself.

Predicate returning True if this object's 'annotation' subelement exists and has content.
isSetAnnotation() boolWhereas the SBase 'notes' subelement is a container for content to be shown directly to humans, the 'annotation' element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for 'annotation'. The element's content type is XML type 'any', allowing essentially arbitrary well-formed XML data content.
SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.
True if a 'annotation' subelement exists, False otherwise.

Predicate returning True if a call to getId() returns a non-empty string.
isSetId() boolFor most objects, this function will return True if its 'id' attribute is set, and False if it is not, or if the object has no 'id' attribute at all. However, for an EventAssignment or a Rule, isSetId() checks whether the 'variable' attribute is set, and for an InitialAssignment, it checks whether the 'symbol' attribute is set. Because those elements will also have an 'id' attribute in SBML Level 3 Version 2 which isSetId() will not check, the function itself is deprecated, and it is recommended to use isSetIdAttribute() in all cases where one needs to know whether the 'id' attribute is set, and to use EventAssignment.isSetVariable(), Rule.isSetVariable() and InitialAssignment.isSetSymbol() when the status of the 'variable' or 'symbol' attributes need to be checked.
SId or a type derived from that, such as UnitSId, depending on the object in question. All data types are defined as follows: letter ::= 'a'..'z','A'..'Z' digit ::= '0'..'9' idChar ::= letter | digit | '_' SId ::= ( letter | '_' ) idChar*The characters
( and ) are used for grouping, the character * 'zero or more times', and the character | indicates logical 'or'. The equality of SBML identifiers is determined by an exact character sequence match; i.e., comparisons must be performed in a case-sensitive manner. This applies to all uses of SId, SIdRef, and derived types.Users need to be aware of some important API issues that are the result of the history of SBML and libSBML. Prior to SBML Level 3 Version 2, SBML defined 'id' and 'name' attributes on only a subset of SBML objects. To simplify the work of programmers, libSBML's API provided get, set, check, and unset on the SBase object class itself instead of on individual subobject classes. This made the get/set/etc. methods uniformly available on all objects in the libSBML API. LibSBML simply returned empty strings or otherwise did not act when the methods were applied to SBML objects that were not defined by the SBML specification to have 'id' or 'name' attributes. Additional complications arose with the rule and assignment objects: InitialAssignment, EventAssignment, AssignmentRule, and RateRule. In early versions of SBML, the rule object hierarchy was different, and in addition, then as now, they possess different attributes: 'variable' (for the rules and event assignments), 'symbol' (for initial assignments), or neither (for algebraic rules). Prior to SBML Level 3 Version 2, getId() would always return an empty string, and isSetId() would always return False for objects of these classes.
With the addition of 'id' and 'name' attributes on SBase in Level 3 Version 2, it became necessary to introduce a new way to interact with the attributes more consistently in libSBML to avoid breaking backward compatibility in the behavior of the original 'id' methods. For this reason, libSBML provides four functions (getIdAttribute(), setIdAttribute(), isSetIdAttribute(), and unsetIdAttribute()) that always act on the actual 'id' attribute inherited from SBase, regardless of the object's type. These new methods should be used instead of the older getId()/setId()/etc. methods unless the old behavior is somehow necessary. Regardless of the Level and Version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have identifiers). If the object in question does not posess an 'id' attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the identifier to be set, nor will it read or write 'id' attributes for those objects.
True if the 'id' attribute of this SBML object is set, False otherwise.

Predicate returning True if this object's 'metaid' attribute is set.
isSetMetaId() boolID, the XML identifier type, which means each 'metaid' value must be globally unique within an SBML file. The latter point is important, because the uniqueness criterion applies across any attribute with type ID anywhere in the file, not just the 'metaid' attribute used by SBML—something to be aware of if your application-specific XML content inside the 'annotation' subelement happens to use the XML ID type. Although SBML itself specifies the use of XML ID only for the 'metaid' attribute, SBML-compatible applications should be careful if they use XML ID's in XML portions of a model that are not defined by SBML, such as in the application-specific content of the 'annotation' subelement. Finally, note that LibSBML does not provide an explicit XML ID data type; it uses ordinary character strings, which is easier for applications to support.True if the 'metaid' attribute of this SBML object is set, False otherwise.| def libsbml.SBMLDocument.isSetModel | ( | self | ) |

Predicate returning True if this object has a ModelHistory object attached to it.
isSetModelHistory() boolTrue if the ModelHistory of this object is set, False otherwise.
|

Predicate returning True if this object's 'name' attribute is set.
isSetName() boolThe 'name' attribute is optional and is not intended to be used for cross-referencing purposes within a model. Its purpose instead is to provide a human-readable label for the component. The data type of 'name' is the type string defined in XML Schema. SBML imposes no restrictions as to the content of 'name' attributes beyond those restrictions defined by the string type in XML Schema.
The recommended practice for handling 'name' is as follows. If a software tool has the capability for displaying the content of 'name' attributes, it should display this content to the user as a component's label instead of the component's 'id'. If the user interface does not have this capability (e.g., because it cannot display or use special characters in symbol names), or if the 'name' attribute is missing on a given component, then the user interface should display the value of the 'id' attribute instead. (Script language interpreters are especially likely to display 'id' instead of 'name'.)
As a consequence of the above, authors of systems that automatically generate the values of 'id' attributes should be aware some systems may display the 'id''s to the user. Authors therefore may wish to take some care to have their software create 'id' values that are: (a) reasonably easy for humans to type and read; and (b) likely to be meaningful, for example by making the 'id' attribute be an abbreviated form of the name attribute value.
An additional point worth mentioning is although there are restrictions on the uniqueness of 'id' values, there are no restrictions on the uniqueness of 'name' values in a model. This allows software applications leeway in assigning component identifiers.
Regardless of the level and version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have names). If the object in question does not posess a 'name' attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the name to be set, nor will it read or write 'name' attributes for those objects.
True if the 'name' attribute of this SBML object is set, False otherwise.

Predicate returning True if this object's 'notes' subelement exists and has content.
isSetNotes() boolThe optional SBML element named 'notes', present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the 'notes' element would be to contain formatted user comments about the model element in which the 'notes' element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for 'notes', allowing users considerable freedom when adding comments to their models.
The format of 'notes' elements must be XHTML 1.0. To help verify the formatting of 'notes' content, libSBML provides the static utility method SyntaxChecker.hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and 3 specifications have considerable detail about how 'notes' element content must be structured.

Replaces all uses of a given meta identifier attribute value with another value.
renameMetaIdRefs(string oldid, string newid)
ID; the SBML object attribute itself is typically named metaid. All attributes that hold values referring to values of type ID are of the XML data type IDREF. They are also sometimes informally referred to as 'metaid refs', in analogy to the SBML-defined type SIdRef.This method works by looking at all meta-identifier attribute values, comparing the identifiers to the value of oldid. If any matches are found, the matching identifiers are replaced with newid. The method does not descend into child elements.

Replaces all uses of a given SIdRef type attribute value with another value.
renameSIdRefs(string oldid, string newid)
SId.

These and other methods of libSBML refer to the type SIdRef for all Levels of SBML, even if the corresponding SBML specification did not explicitly name the data type.This method works by looking at all attributes and (if appropriate) mathematical formulas in MathML content, comparing the referenced identifiers to the value of oldid. If any matches are found, the matching values are replaced with newid. The method does not descend into child elements.

These and other methods of libSBML refer to the type UnitSIdRef for all Levels of SBML, even if the corresponding SBML specification did not explicitly name the data type.This method works by looking at all unit identifier attribute values (including, if appropriate, inside mathematical formulas), comparing the referenced unit identifiers to the value of oldid.

Replaces the given top-level element within the 'annotation' subelement of this SBML object and with the annotation element supplied.
SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.
This method determines the name of the element to be replaced from the annotation argument. Functionally it is equivalent to calling removeTopLevelAnnotationElement(name) followed by calling appendAnnotation(annotation_with_name), with the exception that the placement of the annotation element remains the same.

Sets the value of the 'annotation' subelement of this SBML object.
The content of annotation is copied, and any previous content of this object's 'annotation' subelement is deleted.
Whereas the SBase 'notes' subelement is a container for content to be shown directly to humans, the 'annotation' element is a container for optional software-generated content not meant to be shown to humans.

Call this method will result in any existing content of the 'annotation' subelement to be discarded. Unless you have taken steps to first copy and reconstitute any existing annotations into the annotation that is about to be assigned, it is likely that performing such wholesale replacement is unfriendly towards other software applications whose annotations are discarded.

setConsistencyChecks(long category, bool apply)
Controls the consistency checks that are performed when SBMLDocument.checkConsistency() is called.
This method works by adding or subtracting consistency checks from the set of all possible checks that SBMLDocument.checkConsistency() knows how to perform. This method may need to be called multiple times in order to achieve the desired combination of checks. The first argument (category) in a call to this method indicates the category of consistency/error checks that are to be turned on or off, and the second argument (apply, a boolean) indicates whether to turn it on (value of True) or off (value of False).
The possible categories (values to the argument category) are the set of constants whose names begin with the characters LIBSBML_CAT_ in the interface class libsbml. The following are the possible choices:
LIBSBML_CAT_GENERAL_CONSISTENCY: Correctness and consistency of specific SBML language constructs. Performing this set of checks is highly recommended. With respect to the SBML specification, these concern failures in applying the validation rules numbered 2xxxx in the Level 2 Versions 2–4 and Level 3 Versions 1–2 specifications.
LIBSBML_CAT_IDENTIFIER_CONSISTENCY: Correctness and consistency of identifiers used for model entities. An example of inconsistency would be using a species identifier in a reaction rate formula without first having declared the species. With respect to the SBML specification, these concern failures in applying the validation rules numbered 103xx in the Level 2 Versions 2–4 and Level 3 Versions 1–2 specifications.
LIBSBML_CAT_UNITS_CONSISTENCY: Consistency of measurement units associated with quantities in a model. With respect to the SBML specification, these concern failures in applying the validation rules numbered 105xx in the Level 2 Versions 2–4 and Level 3 Versions 1–2 specifications.
LIBSBML_CAT_MATHML_CONSISTENCY: Syntax of MathML constructs. With respect to the SBML specification, these concern failures in applying the validation rules numbered 102xx in the Level 2 Versions 2–4 and Level 3 Versions 1–2 specifications.
LIBSBML_CAT_SBO_CONSISTENCY: Consistency and validity of SBO identifiers (if any) used in the model. With respect to the SBML specification, these concern failures in applying the validation rules numbered 107xx in the Level 2 Versions 2–4 and Level 3 Versions 1–2 specifications.
LIBSBML_CAT_OVERDETERMINED_MODEL: Static analysis of whether the system of equations implied by a model is mathematically overdetermined. With respect to the SBML specification, this is validation rule #10601 in the Level 2 Versions 2–4 and Level 3 Versions 1–2 specifications.
By default, all validation checks are applied to the model in an SBMLDocument object unless SBMLDocument.setConsistencyChecks() is called to indicate that only a subset should be applied. Further, this default (i.e., performing all checks) applies separately to each new SBMLDocument object created. In other words, each time a model is read using SBMLReader.readSBML(), SBMLReader.readSBMLFromString(), or the global functions readSBML() and readSBMLFromString(), a new SBMLDocument is created and for that document, a call to SBMLDocument.checkConsistency() will default to applying all possible checks. Calling programs must invoke SBMLDocument.setConsistencyChecks() for each such new model if they wish to change the consistency checks applied.

( and ) are used for grouping, the character * 'zero or more times', and the character | indicates logical 'or'. The equality of SBML identifiers is determined by an exact character sequence match; i.e., comparisons must be performed in a case-sensitive manner. This applies to all uses of SId, SIdRef, and derived types.Users need to be aware of some important API issues that are the result of the history of SBML and libSBML. Prior to SBML Level 3 Version 2, SBML defined 'id' and 'name' attributes on only a subset of SBML objects. To simplify the work of programmers, libSBML's API provided get, set, check, and unset on the SBase object class itself instead of on individual subobject classes. This made the get/set/etc. methods uniformly available on all objects in the libSBML API. LibSBML simply returned empty strings or otherwise did not act when the methods were applied to SBML objects that were not defined by the SBML specification to have 'id' or 'name' attributes. Additional complications arose with the rule and assignment objects: InitialAssignment, EventAssignment, AssignmentRule, and RateRule. In early versions of SBML, the rule object hierarchy was different, and in addition, then as now, they possess different attributes: 'variable' (for the rules and event assignments), 'symbol' (for initial assignments), or neither (for algebraic rules). Prior to SBML Level 3 Version 2, getId() would always return an empty string, and isSetId() would always return False for objects of these classes.
With the addition of 'id' and 'name' attributes on SBase in Level 3 Version 2, it became necessary to introduce a new way to interact with the attributes more consistently in libSBML to avoid breaking backward compatibility in the behavior of the original 'id' methods. For this reason, libSBML provides four functions (getIdAttribute(), setIdAttribute(), isSetIdAttribute(), and unsetIdAttribute()) that always act on the actual 'id' attribute inherited from SBase, regardless of the object's type. These new methods should be used instead of the older getId()/setId()/etc. methods unless the old behavior is somehow necessary. Regardless of the Level and Version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have identifiers). If the object in question does not posess an 'id' attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the identifier to be set, nor will it read or write 'id' attributes for those objects.

This method is the principal way in libSBML to convert models between Levels and Versions of SBML. Generally, models can be converted upward without difficulty (e.g., from SBML Level 1 to Level 2, or from an earlier Version of Level 2 to the latest Version of Level 2). Sometimes models can be translated downward as well, if they do not use constructs specific to more advanced Levels of SBML.
Before calling this method, callers may check compatibility directly using the methods SBMLDocument.checkL1Compatibility(), SBMLDocument.checkL2v1Compatibility(), SBMLDocument.checkL2v2Compatibility(), SBMLDocument.checkL2v3Compatibility(), SBMLDocument.checkL2v4Compatibility(), SBMLDocument.checkL2v5Compatibility(), SBMLDocument.checkL3v1Compatibility(), and SBMLDocument.checkL3v2Compatibility().
The valid combinations of SBML Level and Version as of this release of libSBML are the following:
Strict conversion applies the additional criteria that both the source and the target model must be consistent SBML. Users can control the consistency checks that are applied using the SBMLDocument.setConsistencyChecksForConversion() method. If either the source or the potential target model have validation errors, the conversion is not performed. When a strict conversion is successful, the underlying SBML object model is altered to reflect the new level and version. Thus, information that cannot be converted (e.g. sboTerms) will be lost.
| level | the desired SBML Level. |
| version | the desired Version within the SBML Level. |
| strict | boolean indicating whether to check consistency of both the source and target model when performing conversion (defaults to true ). |

Sets the value of the meta-identifier attribute of this SBML object.
setMetaId(string metaid) intID, the XML identifier type, which means each 'metaid' value must be globally unique within an SBML file. The latter point is important, because the uniqueness criterion applies across any attribute with type ID anywhere in the file, not just the 'metaid' attribute used by SBML—something to be aware of if your application-specific XML content inside the 'annotation' subelement happens to use the XML ID type. Although SBML itself specifies the use of XML ID only for the 'metaid' attribute, SBML-compatible applications should be careful if they use XML ID's in XML portions of a model that are not defined by SBML, such as in the application-specific content of the 'annotation' subelement. Finally, note that LibSBML does not provide an explicit XML ID data type; it uses ordinary character strings, which is easier for applications to support.The string metaid is copied.

The content of notes is copied, and any existing content of this object's 'notes' subelement is deleted.
The optional SBML element named 'notes', present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the 'notes' element would be to contain formatted user comments about the model element in which the 'notes' element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for 'notes', allowing users considerable freedom when adding comments to their models.
The format of 'notes' elements must be XHTML 1.0. To help verify the formatting of 'notes' content, libSBML provides the static utility method SyntaxChecker.hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and 3 specifications have considerable detail about how 'notes' element content must be structured.
The following code illustrates a very simple way of setting the notes using this method. Here, the object being annotated is the whole SBML document, but that is for illustration purposes only; you could of course use this same approach to annotate any other SBML component.

Unsets the value of the 'name' attribute of this SBML object.
unsetName() intThe 'name' attribute is optional and is not intended to be used for cross-referencing purposes within a model. Its purpose instead is to provide a human-readable label for the component. The data type of 'name' is the type string defined in XML Schema. SBML imposes no restrictions as to the content of 'name' attributes beyond those restrictions defined by the string type in XML Schema.
The recommended practice for handling 'name' is as follows. If a software tool has the capability for displaying the content of 'name' attributes, it should display this content to the user as a component's label instead of the component's 'id'. If the user interface does not have this capability (e.g., because it cannot display or use special characters in symbol names), or if the 'name' attribute is missing on a given component, then the user interface should display the value of the 'id' attribute instead. (Script language interpreters are especially likely to display 'id' instead of 'name'.)
As a consequence of the above, authors of systems that automatically generate the values of 'id' attributes should be aware some systems may display the 'id''s to the user. Authors therefore may wish to take some care to have their software create 'id' values that are: (a) reasonably easy for humans to type and read; and (b) likely to be meaningful, for example by making the 'id' attribute be an abbreviated form of the name attribute value.
An additional point worth mentioning is although there are restrictions on the uniqueness of 'id' values, there are no restrictions on the uniqueness of 'name' values in a model. This allows software applications leeway in assigning component identifiers.
Regardless of the level and version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have names). If the object in question does not posess a 'name' attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the name to be set, nor will it read or write 'name' attributes for those objects.

Unsets the value of the 'notes' subelement of this SBML object.
unsetNotes() intThe optional SBML element named 'notes', present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the 'notes' element would be to contain formatted user comments about the model element in which the 'notes' element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for 'notes', allowing users considerable freedom when adding comments to their models.
The format of 'notes' elements must be XHTML 1.0. To help verify the formatting of 'notes' content, libSBML provides the static utility method SyntaxChecker.hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and 3 specifications have considerable detail about how 'notes' element content must be structured.

Performs consistency checking and validation on this SBML document.
validateSBML() longIf this method returns a nonzero value (meaning, one or more consistency checks have failed for SBML document), the failures may be due to warnings or errors. Callers should inspect the severity flag in the individual SBMLError objects returned by SBMLDocument.getError() to determine the nature of the failures.
