Currently, there are only the Arabidopsis(AAtDB) and ACeDB data sets available,
as far as I know, but there are at least ten projects that are in the making;
I am working on one of them. To get an idea of what's to come, take a look at
ACeDB's latest release and look at the file tags.wrm in the wspec directory;
this is where registered developers tag number allotments can be seen- I think
Drosophila, human genome, and mice are among the databases being developed, and
I am currently designing a new database from AAtDB for Chlamydomonas.
