SBML Level 3 Proposals

The following table summarizes the different packages being developed for SBML Level 3 and serves as a jumping-off point for other pages where these efforts are discussed in more detail. The legend below the table explains the symbols used; you can also hover your pointing device over the icons to view a summary. The procedure for proposing new packages is explained on a separate page.

				Prop.	Spec.
Name	Label	Description	PWG list	Stat.	Stat.	libSBML
Level 3 Core	core	The core portion of SBML Level 3.	sbml-discuss
Layout	layout	Support for storing the spatial topology of a model's network diagram. Adjunct to the render package, below.	sbml-layout
Flux Balance Constraints	fbc	Support for constraint-based (a.k.a. steady-state) models.	sbml-flux
Rendering	render	Support for defining the graphical symbols and glyphs used in a diagram of the model. Adjunct to the layout package above.	sbml-render
Hierarchical Model Composition	comp	A means for defining how a model is composed from other models.	sbml-comp
Multistate multicomponent species	multi	Object structures for representing entity pools with multiple states and composed of multiple components, and reaction rules involving them.	sbml-multi
Qualitative Models	qual	Support for models wherein species don't represent quantity of matter & processes are not reactions per se. (E.g.: Boolean nets.)	sbml-qual
Annotations	annot	Support for richer annotation syntax than the regular annotations in SBML Level 3 Core.	sbml-annot
Spatial Processes	spatial	Support for describing processes that involve a spatial component, and describing the geometries involved.	sbml-spatial
Groups	groups	Support for groups of SBML entities. This partially replaces the Level 2 SpeciesType and CompartmentType constructs with a more general mechanism.	sbml-groups
Required Elements	req	Support for fine-grained indication of SBML elements that have been changed by the presence of another package.	sbml-required
Distribution & ranges	distrib	Support for expressing the idea that a given value is not known precisely but falls within some defined distribution or range.	sbml-distrib
Arrays & sets	arrays	Support for expressing arrays or sets of things. Example: an array of identical compartments.	sbml-arrays
Dynamic structures	dyn	Support for creating and destroying entities during a simulation.	sbml-dynamic

Table legend:

• Name: the name of the SBML Level 3 package.

• Label: the short-form label for the package. The label is often used in discussions about the package and in software examples; it is also suggested for use as the XML Namespace prefix for a package.

• Description: a short summary of the purpose of the package.

• PWG: the Package Working Group, described in the development process for SBML Level 3. The PWG name is linked to the mailing list for the group.

• Prop. Stat: proposal status. The following are the possible symbols and their meanings:

• Spec. stat.: specification status. The following are the possible symbols and their meanings:

• libSBML: state of support for the package in libSBML. The following are the possible symbols and their meanings:
