The SBML unit definition facility uses two classes of objects, UnitDefinition and Unit. The approach to defining units in SBML is compositional; for example, meter second –2 is constructed by combining a Unit object representing meter with another Unit object representing second –2. The combination is wrapped inside a UnitDefinition, which provides for assigning an identifier and optional name to the combination. The identifier can then be referenced from elsewhere in a model. Thus, the UnitDefinition class is the container, and Unit instances are placed inside UnitDefinition instances.
A Unit has four attributes named "kind", "exponent", "scale" and "multiplier". It represents a (possibly transformed) reference to a base unit. The attribute "kind" on Unit indicates the chosen base unit. Its value must be one of the text strings listed below; this list corresponds to SBML Level 3:
| ampere | farad | joule | lux | radian | volt |
| avogadro | gram | katal | metre | second | watt |
| becquerel | gray | kelvin | mole | siemens | weber |
| candela | henry | kilogram | newton | sievert | |
| coulomb | hertz | litre | ohm | steradian | |
| dimensionless | item | lumen | pascal | tesla |
A few small differences exist between the Level 3 list of base units and the list defined in other Level/Version combinations of SBML. Specifically, Levels of SBML before Level 3 do not define avogadro; conversely, Level 2 Version 1 defines Celsius, and Level 1 defines celsius, meter, and liter, none of which are available in Level 3. In libSBML, each of the predefined base unit names is represented by an enumeration value in UnitKind_t, discussed in a separate section below.
The attribute named "exponent" on Unit represents an exponent on the unit. In SBML Level 2, the attribute is optional and has a default value of 1 (one); in SBML Level 3, the attribute is mandatory and there is no default value. A Unit also has an attribute called "scale"; its value must be an integer exponent for a power-of-ten multiplier used to set the scale of the unit. For example, a unit having a "kind" value of gram and a "scale" value of -3 signifies 10 –3 
gram, or milligrams. In SBML Level 2, the attribute is optional and has a default value of 0 (zero), because 10 0 = 1; in SBML Level 3, the attribute is mandatory and has no default value. Lastly, the attribute named "multiplier" can be used to multiply the unit by a real-numbered factor; this enables the definition of units that are not power-of-ten multiples of SI units. For instance, a multiplier of 0.3048 could be used to define foot as a measure of length in terms of a metre. The "multiplier" attribute is optional in SBML Level 2, where it has a default value of 1 (one); in SBML Level 3, the attribute is mandatory and has no default value.
As discussed above, SBML defines a set of base units which serves as the starting point for new unit definitions. This set of base units consists of the SI units and a small number of additional convenience units.
Until SBML Level 2 Version 3, there existed a data type in the SBML specifications called UnitKind, enumerating the possible SBML base units. Although SBML Level 2 Version 3 removed this type from the language specification, libSBML maintains the corresponding enumeration type UnitKind_t as a convenience and as a way to provide backward compatibility to previous SBML Level/Version specifications. (The removal in SBML Level 2 Version 3 of the enumeration UnitKind was also accompanied by the redefinition of the data type UnitSId to include the previous UnitKind values as reserved symbols in the UnitSId space. This change has no net effect on permissible models, their representation or their syntax. The purpose of the change in the SBML specification was simply to clean up an inconsistency about the contexts in which these values were usable.)
As a consequence of the fact that libSBML supports models in all Levels and Versions of SBML, libSBML's set of UNIT_KIND_ values is a union of all the possible base unit names defined in the different SBML specifications. However, not every base unit is allowed in every Level+Version combination of SBML. Note in particular the following exceptions:
The alternate spelling "meter" is included in addition to the official SI spelling "metre". This spelling is only permitted in SBML Level 1 models.
The alternate spelling "liter" is included in addition to the official SI spelling "litre". This spelling is only permitted in SBML Level 1 models.
The unit "Celsius" is included because of its presence in specifications of SBML prior to SBML Level 2 Version 2.
avogadro was introduced in SBML Level 3, and is only permitted for use in SBML Level 3 models. The table below lists the symbols defined in the UnitKind_t enumeration, and their meanings.

Disables the given SBML Level 3 package on this object.
This 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:

| pkgPrefix | the XML prefix of the package. |

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.

Returns the value of the "name" attribute of this SBML object.
The "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.

The format of "notes" elements conform to the definition of XHTML 1.0.

To help verify the formatting of "notes" content, libSBML provides the static utility method SyntaxChecker::hasExpectedXHTMLSyntax(); this method implements a verification process that lets callers check whether the content of a given XMLNode object conforms to the SBML requirements for "notes" and "message" structure.

Returns the MIRIAM biological qualifier associated with the given resource.
In 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 values from the enumeration type BiolQualifierType_t.
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 value from the enumeration type BiolQualifierType_t.

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.

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.

Predicate returning true if a call to getId() returns a non-empty string.
For 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.

Predicate returning true if this object's "metaid" attribute is set.
ID, 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.

Predicate returning true if this object's "name" attribute is set.
The "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.

Predicate returning true if this object's "notes" subelement exists and has content.
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.

Predicate to test whether a given string is the name of a valid base unit in SBML (such as "gram" or "mole").
This method exists because prior to SBML Level 2 Version 3, an enumeration called UnitKind was defined by SBML.

This method therefore has less significance in SBML Level 2 Version 3 and Level 2 Version 4, but remains for backward compatibility and support for reading models in older Versions of Level 2.

Removes this object from its parent.
If the parent was storing this object as a pointer, it is deleted. If not, it is simply cleared (as in ListOf objects). This is a pure virtual method, as every SBase element has different parents, and therefore different methods of removing itself. Will fail (and not delete itself) if it has no parent object. This function is designed to be overridden, but for all objects whose parent is of the class ListOf, the default implementation will work.

Removes the top-level element within the "annotation" subelement of this SBML object with the given name and optional URI.
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.
Calling this method allows a particular annotation element to be removed whilst the remaining annotations remain intact.

Replaces all uses of a given meta identifier attribute value with another value.
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.
In SBML, object identifiers are of a data type called SId. In SBML Level 3, an explicit data type called SIdRef was introduced for attribute values that refer to SId values; in previous Levels of SBML, this data type did not exist and attributes were simply described to as "referring to an identifier", but the effective data type was the same as SIdRef in Level 3. 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.

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.

Unsets the value of the "id" attribute of this SBML object.

Unsets the value of the "name" attribute of this SBML object.
The "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.

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.
