[Obo-discuss] Annotating GO and OBO Files

[Simon C. <si...@sa...>]

Greetings,

We're in the process of creating GO flat file and GO OBO file versions
of the eVOC ontologies
(http://obo.sourceforge.net/cgi-bin/detail.cgi?evoc or
http://www.sanbi.ac.za/evoc/).  We would like to annotate the terms with
cDNA libraries but it seems neither the GO flat file nor the newer GO
OBO file formats make provision for this.

I am aware of the GO annotation file format but that is designed for
linking genes or gene products to terms and is not really flexible
enough for out purposes.  Specifically there are numerous mandatory
fields which we can't assign useful values to.

How are other OBO people handling annotations when using the GO
formats?  Or other formats for that matter?
