Actually they are. Keywords are defined in the CellML metadata
specifications and are already being used in various files. Feel free to
check the CellML files of the old repository and scroll down the to keyword
section. An example follows.

>From http://www.cellml.org/examples/models/beeler_reuter_model_1977.html:

<!-- Keyword(s) -->
<bqs:reference rdf:parseType="Resource">
<dc:subject rdf:parseType="Resource">
<bqs:subject_type>keyword</bqs:subject_type>
<rdf:value>
<rdf:Bag>
<rdf:li>ventricular myocyte</rdf:li>
<rdf:li>electrophysiological</rdf:li>
</rdf:Bag>
</rdf:value>
</dc:subject>
</bqs:reference>

I do understand it may be different from the full CellML metadata
specification as found in
http://www.cellml.org/specifications/metadata/cellml_metadata_1.0#sec_bqs,
but all other models pretty much follow this RDF format and so I wound up
having to follow the above format to pick up the keyword metadata.

That is already the case, the 'categories' *are* keywords that are chosen by
Peter as a selectable choice in the filtering drop box for the repository
listing.

In the Edit Keyword interface, any keyword of the model that matches one of
the 'blessed' keywords will be highlighted in the category list. All other
keywords will be in the lines field editor. Feel free to log into the site
(I assume you have an account) and try out the editing interface. I do agree
it is currently slightly clunky, but James has no complaints with it and he
has already added/verified keyword for half the curated models (I think) of
the repository.

Again, the category field is a *subset* of keywords to limit the number of
choices in the filtering menu and not a distinct entity.

Hope this clear things up.

Tommy.
