Hi folks, Nathann Cohen recently [1] brought up the topic of using the ISGCI graph database [2] in Sage. During several weeks of email communication, we have reached agreement with upstream developers of ISGCI to have the database licensed under the CC terms below. Under such terms, Nathann and I would like to know if the database could be distributed as part of Sage. I know that several databases are distributed with Sage, but I'm not sure of the licensing terms governing those databases. A database is different from source code, so it needs another type of license. This might be a non-issue because the Sage standard documentation is licensed under a slightly different CC license. I would like to request comments to see whether ISGCI could be distributed as part of Sage with the licensing terms below.
