Annotating a feature with multiple types of cvterms

[almasaeed2010]

Hello all,

We are working on a way to add additional information to a feature_cvterm association. We would like to specify an analysis_id for a feature_cvterm record. We would also like to specify whether this cvterm is a relationship term.

What we are trying to create is something to similar to this page: https://www.arabidopsis.org/servlets/Search?action=search&type=annotation&tair_object_id=2025391&locus_name=AT1G01620

Where the columns relationship type and keyword are cvterms and evidence is an analysis.

Currently chado provides a way for us to associate a publication to a feature but it doesn't offer a way to link analyses. In our case, some annotations don't necessarily have a publication to link to but do have analyses (BLAST and InterProScans for example).

Does chado offer a way to do this?

Thanks!
