I believe Google's actually been making a bit of progress on
standardizing KML.
See: http://www.opengeospatial.org/pressroom/newsletters/200701#C2
'The Planning Committee strongly endorsed the proposal by Google to
bring KML into the OGC standards process. The first step will be to
perform limited harmonization with OGC and ISO standards and then
produce a document for consideration by the OGC members for release as
OGC Best Practices. There will also be a public discussion list created
so that the OGC KML related work will remain open and transparent.'
But yes, the best route would be to have KML as a profile of GML,
actually referencing the GML schemas for the geometry constructs, and
doing the rest as they do. Indeed it would be nice just to have an
official schema for KML.
best regards,

isn't that a bit in contradiction with the fact that so far, Google
hasn't been trying much to harmonize KML with GML, for instance ?
I agree that in many cases KML is a better choice than GML, because of
GML's complexity. But I feel like it would not have been much of an
effort to define KML as a subset/profile of GML. And thereby get
immediate interoperability. Am I wrong here ?

A Google View of Data Sharing
By Joe Francica
Directions Mag
(Feb 01, 2007)

"At the Map World Forum in Hyderabad, India, Michael Jones, chief
technologist of Google Earth, shared his views on the benefits of
standards. Google is an Open Geospatial Consortium (OGC) principal
member and supports efforts to encourage standards adoption. Google has
a "democratized" view of data sharing which begins with the vast amount
of information that has already been captured by those working in GIS.
Jones believes in ways to provide better access to those data. He
explained that most geospatial data today is locked away in workstations
managed by proprietary software. He was perhaps referring to those data
controlled by local and state government departments. "We have to
envision a future world where data is published," he said. "We may want
to knock on the door of the Survey of India and ask them what data they
want to share with the world." Jones' vision is to have "all" geospatial
information available to the world and indexed in a way that it can be
accessed by those who need it. "Google has a mission to allow more data
to be available and interoperable," he said. "
