The GS software has been made available as a free download by SRI International and the National Institute of Education (Singapore)

The source code is available to project collaborators who sign a licensing agreement for research purposes.

For purposes of proposals and publications, the following messaging is to be applied where reference to “Copyrighted Material” is made:


Copyrighted Material

The Group Scribbles software is copyrighted by SRI International, and has a patent pending. With SRI and NIE (Singapore)as partners on this proposal, the project has full access to the Group Scribbles software--both source code and binaries.

The Group Scribbles server runs on the free, open-source web and database server applications JBOSS and MySQL.

The Group Scribbles source code is also available to the public through an individual or organization software license. The gist of the license is that Licensees are encouraged, but not required, to contribute code back to SRI's and NIE’s Group Scribbles project.


System Requirements

For good user experience, the server machine and client machine must have the following specifications:

       Server

Operating System

Microsoft Window Server 2003 or 2008. (Although Microsoft Window Server 2008 provides better performance, for schools under MOE, Microsoft Window Server 2003 should be used instead due to MOE policy).

The operating system should be solely used for Group Scribbles and not running any irrelevant application or process. (For a server that has been used for other purpose, it is advisable to reformat the entire OS).

The following port should be unblocked and free for the Group Scribbles applications.
