The OpenGIS Consortium publicly posted the Web Map Server Interface
Specification on their website <http://www.opengis.org/> with very
little fanfare.  An official announcement from them is in the
works, but in the meantime I just wanted to let you know that the
spec is available as a 550kB PDF document at
<http://www.opengis.org/techno/specs/00-028.pdf>

The Web Map Server Interface, by the way, is a core specification
adopted by the Digital Earth Reference Model.  WM version 1.0
standardizes three things: (1) how to advertise a collection of
georeferenced data, including bounding boxes, coordinate systems,
etc; (2) how to request a specific georeferenced map of a data
layer; and, optionally, (3) how to query the server for information
about a feature shown in a map layer.  Phase 2 of the Web Mapping
Testbed will address issues not yet covered by the spec; a formal
RFQ/RFP will be issued soon by OGC.
