[Bioperl-l] GO ontology browser module available

[Chris Mungall]

Hi Mark

Sorry you haven't heard back from us GO people, all the GO developers are
working full time on another project at the moment, just keep at us and
we'll respond eventually.

We should fix the problem of the SGML embedded within XML - Brad, can you
see to this?

In the meantime, have you tried using either the flat files or the mysql
database? there are perl modules for using either of these in the GO
repository.

As to where you deposit your code, I'd love to keep all the GO code
together in one cvs repository. Unfortunately, the stanford cvs server is
highly restricted. I was considering moving the perl software portion of
GO away from the stanford cvs server into the Berkeley one, for this
reason. Another option would be to use bioperl cvs for all of GO-perl, if
people are willing.

if anyone's interested the GO module docs are here:
