Thanks for the catch, Adam

This is corrected in the latest version, at
http://www.gils.net/context-set.html

My biggest issue in developing this context set is: What should we do when
there is more than one index name with the same semantics within a given
context set?

For instance, in the Dublin Core context set
http://www.loc.gov/z3950/agency/zing/cql/context-sets/dc.html, the index
"author" is not included. Yet "dc.author" shows up often (e.g., examples
given at http://gita.grainger.uiuc.edu/registry/sru/test.htm ). My sense is
that Dublin Core in practice accepts "author" as a semantic equivalent of
"creator" (at least with respect to "document-like objects").

So, should the CQL context set list "dc.author" as an alias for "dc.creator"?
