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. | |||||
|---|---|---|---|---|---|---|

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:
| Proposal approved |
| Proposal period is ongoing |
| Need identified and an approach has been proposed |
| Need identified, but no proposals have been formulated yet |
| Stalled (no notable activity in past year) |
- Spec. stat.: specification status. The following are the possible symbols and their meanings:
| Final specification approved and two independent implementations are available |
| Draft specification and/or implementations are in development |
| Specification started but no draft is available yet |
| Specification work has not started |
|
| Stalled (no notable activity in past year) |
- libSBML: state of support for the package in libSBML. The following are the possible symbols and their meanings:
| A full (with respect to the specification) implementation is available |
| A prototype or test implementation is available |
| An implementation is in development but not yet publicly released |
| Implementation work has not yet started |
