This is the top page for the SBML wiki area on SBML.org. It serves as a community-maintained resource. The wiki is suitable for long explanations, documents, proposals, etc., while the forums are more suitable for rapid discussion and exchange.
Much of the information on this page may not make sense without some knowledge of the SBML specification. Some other questions may be answered in the SBML FAQ. If you have any suggestions or questions, please don't hesitate to mention them on one of the mailing lists or by contacting firstname.lastname@example.org.
SBML Level 3
SBML Level 3 is modular, in the sense of having a defined core set of features and optional packages adding features on top of the core. This modular approach means that models can declare which feature-sets they use, and likewise, software tools can inform users about the packages they support.
SBML Level 3 Status Summary Table
The status of package efforts is now listed in a new set of packages oriented to the specifications rather than the proposals.
Each Level 3 package effort has its own detailed status page. Please follow the links below for more information, including any specifications that may be available. This list is in alphabetical order by package label. The information in this table is drawn from the master table for Level 3 package statuses.
| Package name|
& link to info page
|Arrays|| ||Support for expressing arrays of things||Draft available|
|Hierarchical Model Composition|| ||A means for defining how a model is composed from other models||Released|
|Distributions|| ||Support for encoding models that sample values from statistical distributions||Draft available|
|Dynamic Processes|| ||Support for creating and destroying entities during a simulation||Draft available|
|Flux Balance Constraints|| ||Support for constraint-based (a.k.a. steady-state) models||Released|
|Groups|| ||A means for grouping elements||Released|
|Layout|| ||Support for storing the spatial topology of a network diagram; adjunct to the render package||Released|
|Extended Math|| ||A suite of packages that collectively allow MathML beyond the subset allowed in SBML core.||Not started|
|Multistate and Multicomponent Species|| ||Object structures for representing entity pools with multiple states and composed of multiple components, and reaction rules involving them||Released|
|Qualitative Models|| ||Support for models wherein species do not represent quantity of matter & processes are not reactions per se||Released|
|Rendering|| ||Support for defining the graphical symbols and glyphs used in a diagram of the model; adjunct to the layout package||Draft available|
|Spatial Processes|| ||Support for describing processes that involve a spatial component, and describing the geometries involved||Draft available|
|Annotations|| ||Support for richer annotation syntax than the regular annotations in SBML Level 3 Core||Superceded by COMBINE annotations effort|
|Required Elements|| ||Support for fine-grained indication of SBML elements that have been changed by the presence of another package||Retired due to decreased demand|
SBML Level 3 package specification documents are written using a standardized LaTeX template developed by the SBML Team for this purpose. The template is freely available for use by other efforts.

The following content came from older versions of the SBML.org website, with some modifications and updates done more recently as people have had time and noticed things. Some of the content is not relevant anymore thanks to more recent versions of SBML, but they're kept around for nostalgia and historical reference.
