SBML Level 3 Qualitative Models (“qual”)

This page summarizes the current development status of the SBML Level 3 Qualitative Models Package (known by the label “qual”). If you use this Package in your work, please cite the publication associated with the package in addition to the core Level 3 specification, to give credit to the package developers.

This table is generated automatically from the row for “qual” in the SBML Level 3 Package Status spreadsheet.
Package purpose:Support for models wherein species do not represent quantity of matter & processes are not reactions per se
Package status:Final specification approved and two independent implementations are available
Latest version:Version 1 Release 1 (17 May 2013)

Publication DOI:10.1515/jib-2015-270
RELAX NG schema:A final schema is available
LibSBML status:A full (with respect to the specification) implementation is available
JSBML status:A full (with respect to the specification) implementation is available
Working group mailing list:sbml-qual

About the schemas: for finalized Level 3 Packages, libSBML and JSBML provide built-in validation, and the use of a schema is unnecessary. For not-yet-finalized Packages and applications not using libSBML or JSBML, the basic RELAX NG schemas enable syntactic validation using an RNG schema processor. A separate page provides more information about the use of schemas.

Notes about this specification

The “qual” specfication is considered stable and in active use.

Notes about third-party application support

Some historical developments:

2013-07-08: The Cell Collective supports the SBML Qualitative Models package. The Cell Collective is a web-based platform for the construction, simulation, and analysis of Boolean-based models. Models published on the site can also be downloaded as SBML using the Level 3 qual format.

2012-11-29: The latest prerelease version of BoolNet supports the SBML Qualitative Models package.

2012-08-14: The Path2Models project and BioModels Database have created over 142,000 models using the SBML Level 3 qualitative models package.

2012-08-14: GinSim and CellNetOpt are two software systems that implement support for the qual package. Their developers have also been involved in authoring the specification.
