[mapserver-users] Keywords from multiple vocabularies

[Schweitzer, Peter]

The real need would be to specify, for each keyword, what vocabulary
it comes from.  Perhaps keywords should be specified using a URI, as
in RDF?  The next question is what system reads these keywords and
does something useful with them, and how does it expect these to be
arranged?
