Re: Tr: Retrieve Information from GenBank file

I'm more interesting in the features (regqrding protein-ID, taxon, xref, product) and retrieving information about articles (authors, title). I don't look at all to the sequence data.
My purpose is to be able to read the GenBank file to retrieve those information so that I can proceed a conversion to a semantic rdf format file. I'm working on a specific gene at the moment but it would be interesting to extend to any GenBank file in the future.

Thanks,

Jean-Charles
