The SBML wiki area on SBML.org 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.
SBML Level 3
The next Level of SBML will be 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 declare which packages they support.
The following table both summarizes the different packages being developed for SBML Level 3, and serves as a jumping-off point for other pages where the efforts are discussed in more detail.
| Area name | Description | Label |
|---|---|---|
| Level 3 Core | The core portion of SBML Level 3. Expected to be roughly SBML Level 2 Version 4, plus some technical modifications to support SBML Level 3 packages and its implications. | core
|
| Layout | A means for representing the way that a diagram of the model is meant to be organized spatially on a printed page or a computer monitor. The "SBML Level 3 Layout" package is concerned with the topology of the diagram, while the SBML Level 3 Rendering package is concerned with the glyphs and symbols that are used in the diagram. | layout
|
| Rendering | A means for defining the graphical shapes and symbols that are meant to be used in a diagram of the model. It is an adjunct to the SBML Level 3 Layout package. | render

| Multistate multicomponent species | Object structures for representing entity pools with multiple states and composed of multiple components, and reaction rules involving them. | multi

| Hierarchical Model Composition | A means for defining how a model is composed from other models. | comp
|
| Qualitative models | Object structures for representing models in which the entities pools represent discrete levels of activities rather than amount of matter. The processes involving them are not describable as reactions per se (i.e., not events-per-time) but rather as transitions between states. Boolean networks, logical models and some petri-nets are examples of this type of model. | qual

| Distribution & ranges | Support for expressing the idea that a given value is not known precisely but falls within some defined distribution or range. | distrib
|
| Spatial diffusion | Support for describing processes that involve a spatial component. | spatial
|
| Geometry | Object structures for describing one-, two- and three-dimensional characteristics of SBML entities. Example: the shape of a three-dimensional compartment. | geom
|
| Arrays & sets | Support for expressing arrays or sets of things. Example: an array of identical compartments. | arrays
|
| Dynamic structures | Support for creating and destroying entities during a simulation. | dyn
|
| Steady-state models | Support for models quantitatively representing steady-state(s) of a system. An example of such an approach is the class of models known as flux-balance analysis. | steady

25 August 2008: Our original sbml.org server hardware failed in March. This occurred slightly before we were ready with the new site. We have put the new server and website online (you're reading it now), but the content of some areas still needs to be filled back in. This is happening rather slowly, but eventually we will put everything back. We apologize for the delay and inconvenience.
