What features are planned for future releases?

Can STEM be used for more than just disease modeling?

In principle, yes (but only in principle). The core components of STEM implement a graph based spatiotemporal simulation engine. The components that extend it to disease modeling are in separate plug-ins and integrate themselves using Eclipse extension points. Today we are focused on supporting a framework for modeling diseases.

How can I contribute to STEM ?

New Contributors to STEM are always welcome (please contact the developers). This includes not only researchers interested in disease modeling but also experts in GIS data or any other data that might be important in understanding or modeling the spread of infectious disease. We also welcome input from users and contributions to our documentation.

To contribute to STEM, please use the standard Eclipse process. Open a "bug" in our bugzilla (https://bugs.eclipse.org/bugs/) A bug can be more than just a new defect - it can also be a new feature or other contribution. You can attach your contribution as a "patch" to your bug (http://wiki.eclipse.org/index.php/Bug_Reporting_FAQ) Please also feel free to e-mail the STEM development team, many of whom are Eclipse Committers The STEM Development Team. For those interested in joining the project, we also have a weekly phone call and a newsgroup, etc.

Where can I get more help ?

Please start by reading the extensive documentation on our wiki and our website. The STEM community also has a weekly conference call. The call is held most Wednesdays at 1PM ET (10AM PDT). For more information, or if you wish to join, please send mailto:judyvdouglas@verizon.net
