While the official GILS standard doesn't address the use of META tags (it
is an application profile for the Z39.50 Information Retrieval protocol and
thus addresses the searching and retrieval from databases of structured
metadata), the similarity of the data elements to DC is not an accident.
The objectives of the two specifications overlap somewhat, and some work
has gone into aligning GILS with the evolving DC.
The Nordic Web Index (NWI) project, a distributed index of WWW-based
resources in the nordic countries, essentially uses GILS to provide
structured access to a distributed database of DC-like data, extracted from
the live pages by a robot. One of the access points to the system is at
<http://nwi.dtv.dk/index_e.html>.
We have found GILS specifically and Z39.50 in general to be a wonderful
mechanism to provide a structured interface to one or more DC-structured
databases. The best source of information is at <http://www.usgs.gov/gils/>.
