All right, I warned you this was a trick question. The answer is: all of the above! Every one of the projects listed (and all the write-ins too, for that matter) have good basis for claiming to be the “first” project on Tigris.Org:
ArgoUML, the leading open source UML modeling tool, sits at the top of a family of dozens of component projects, translations, and extensions. The core project was started in 1998, two years before there even was a Tigris.Org! It was already established as an open source project when it moved into Tigris.
www, a write-in, is the project where the web pages of the generic Tigris.Org site are stored. It’s created automatically by the CollabNet Enterprise Edition software that powers Tigris, and so it was the first project created within the Tigris site itself.
gef is a graph editing library that can be used to construct many, high-quality graph editing applications. This project was created within Tigris in February of 2000, making it the first still-active project created within Tigris.
Although the projects above now all use Subversion, they were all originally created using CVS. This begs a new question: what about the first project created within Tigris and also in Subversion? It wasn’t Subversion itself: Subversion boot-strapped fairly early, but it was born as a CVS project. Naturally, of course: Subversion (the software) didn’t exist at the time Subversion (the project) was being created.
But there is a project whose files were first created within Subversion (the software), and in fact within Subversion (the project), then later moved out to become its own project. Since those files were created in September of 2000, arguably this qualifies
cvs2svn as the first project created within Subversion on Tigris.Org.
But finally, what’s the first project created, as itself, using Subversion (the software), on Tigris.Org? This is a bit hard to trace down, as the early versions of import didn’t always preserve all the key information, but I believe this trophy goes to
argouml-stats, which was created on Tigris.Org, as a Subversion project, in April of 2005. (There’s that ArgoUML family again!) This project serves the build/test status for the project family as a whole, an extension of the automated build facilities.
