Google Code is closing down. I had a few projects running there and participated in semanticchemistry which hosts the CHEMINF ontology (doi:10.1371/journal.pone.0025513). But also ChemoJava, an extension of the CDK with GPL-licensed bits.
Fortunately, they have an exporter which automates the migration of the project to GitHub. And this is now in progress. Because the exporter is seeing a heavy load, they warn about a export times of up to twelve hours! The "0% complete" is promising, however :)
For the semanticchemistry project, I have asked the other people involved where we want to host it, as GitHub is just one of the options. A copy does not hurt anyway, but the one I am currently making may very well not be the new project location.
When you migrate your own projects and you published your work referring to this Google Code project page, please also leave a comment on PubMed Commons pointing readers to the new project page!
