OGC Seeks Comment on OGC Candidate KML 2.2 Standard

The Open Geospatial Consortium, Inc. announced a call for public comment
on a draft OpenGIS Encoding Standard (OGC KML) for KML 2.2, a XML-based
encoding schema for expressing geographic annotation and visualization
on existing or future web-based online maps (2D) and Earth browsers (3D).
The draft OGC KML 2.2 standard formalizes the KML 2.2 model and language
while remaining backwards compatible with existing KML 2.2 files. In
comparison with the Google KML 2.2 Reference, the draft standard defines:
(1) the KML 2.2 geometry encoding and interpolation model; (2) an
extension model in support of application profiles; (3) conformance
requirements and test cases. The submission of KML into the OGC consensus
process by the RFC Submission team led by Google and Galdos Systems Inc.
ensures that KML will be aligned with international best practices and
standards, thereby enabling greater uptake and interoperability of Earth
browser implementations. The public comment period will remain open
until January 4, 2008.
