The Alexandria Digital Library Project has just released version 1.0
of the "ADL Gazetteer Protocol" at


What the heck is a gazetteer?  From the intro...


   A gazetteer maps geographic placenames (the names of natural
   features such as mountains and lakes and the names of human
   constructs such as cities and states) to coordinate-based
   geographic locations...

   The services associated with a gazetteer are largely oriented
   around searching: finding a place given all or part of its name
   ("where is the place named 'Santa Barbara'?"); finding all places
   in a given region ("what's here?"); and finding places that have
   some kind of relationship to a known place ("what schools are
   within Santa Barbara County?").

   This specification first semi-formally defines an abstract model of
   a gazetteer.  That model is then used as the basis for defining a
   set of services (i.e., a set of network-invokable functions),
   several report formats, and a query language.


The protocol is defined using XML schemas, and it is built on GML
(http://www.opengis.net/gml/), which also uses XML schemas.

Work is currently underway at several organizations creating clients
and servers that use the protocol.  Time will tell how the use of XML,
and XML schemas in particular, facilitates the development and use of
such protocols.
