Hello Mike, Mano is right in his answer, at this point in time the KML recognised by Google Earth is the OGC standard version, there is no KML 3.0 as such. You raise an interesting question as to the future of KML, it really is now open to the community to nominate changes to KML to allow new features implemented in software applications to become part of KML.
This process is managed through the technical committee of the OGC, and I expect indeed hope to see new elements of KML promoted by the likes of Microsoft, ESRI or even yourself :-) To be abolsutly clear Google has not more influrence over future changes to KML than any other OGC member.

What I was really asking about was the de-facto KML that google implements unilaterally in google earth way ahead formal OGC adoption. There are many KML elements in google earth that are -not- part of KML 2.2. e.g. KML3.0++ Doesn't google still control the future of KML through these pre-standard implementations? My other question is what is left out of the OGC KML2.2 spec ? I understand that a fair amount of 3d grammar is not part of KML 2.2. What else? In addition to a formal Google response (yours), I was hoping that someone like Raj Singh, Carl Reed, Ron Lake, or Andrew Turner might also comment. Thanks for any insights you can share Mike Mano Marks wrote: Hi y'all, I just wanted to address a couple of the points raised on the thread. To be completely out there, in case you missed my email address, I work for Google supporting Geo APIs. Mike asked if the OGC owns the future of KML. It does. Google no longer owns any KML IP.. The OGC owns all of it. Google is a member of the OGC, and we hope to be one of the drivers of innovation, but we don't own it or have any special privileges other OGC members don't have. Allan, you asked for a non license-agreement copy of something. Did you mean of the spec or just the documentation? This link: http://schemas.opengis.net/kml/2.2.0/ doesn't require signing a license Also, the KML 2.2 SWG at OGC is also open: http://www.opengeospatial.org/projects/groups/kml2.2swg Also, the KML docs on Google's site are pretty up to date. http://code.google.com/apis/kml/documentation/ If it is a different doc, I can see if I can get it for you.

The Open Geospatial Consortium (OGC), an international standards body, has announced the completion of KML's standardization process. KML has become an OGC Standard, and the OGC will take responsibility for maintaining and extending it. This transfer of ownership is a strong reflection of Google's commitment to open standards. Fundamentally, our interest is not to control information, but rather to encourage its spread." Despite this announcement , does the OGC community actually now 'own' the future of kml? I'm not sure. Perhaps someone more knowledgeable can comment on whether not Google actually still controls KML destiny, with all of their queued up kml3.0 and beyond features and extensions they can unilaterally adopt and implement in google earth, before submission or adoption by OGC committees. I'm also wondering about highlights of alignment with GML, and what major elements are left out or postponed in this 'standard' version. Some 3d elements perhaps? Raj or Carl or Ron anyone in the OGC KML groups care to share any comments? (Andrew?) ------------------------------------------------------------------------------------- http://www.opengeospatial.org/pressroom/pressreleases/857 OGC(R) Approves KML as Open Standard Wayland, Mass., April 14, 2008 - The members of the Open Geospatial Consortium, Inc. (OGC) today announced the approval of the OpenGIS(R) KML Encoding Standard (OGC KML), marking KML's transition into an open standard which will be maintained by the OGC. Developers will now have a standard approach for using KML to code and share visual geographic content in existing or future web-based online maps and 3D geospatial browsers like Google EarthTM. "We are pleased to see the adoption of KML as an OGC standard," said Ron Lake, chairman and chief executive officer of Galdos Systems Inc. "We believe that this is a major step forward for the OGC and for the entire geographic information community, as it provides the first broadly accepted standard for the visualization of geographic information." "Geographic data adds tremendous value to the online experience. More and more people are looking for ways to incorporate location information into their online content," said Michael Weiss-Malik, KML product manager for Google. "The standardization of KML makes it possible for both novice and expert users alike to publish and share geographical information in an open format. It's not unlike web browsers' standardized support for HTML, which allows any web browser to read any web page." KML version 2.2 was brought into the OGC consensus process by a submission team led by Google and Galdos Systems Inc. KML is an XML-based programming language, originally developed to manage the display of geospatial data in Google Earth. It's still used heavily in Google Earth but is also supported by a variety of vendors' tools and mapping websites. The OpenGIS KML 2.2 Encoding Standard formalizes the KML 2.2 model and language while remaining backwards compatible with existing KML 2.2 files and tools. In comparison with the GoogleTM KML 2.2 Reference, the standard defines: * the KML 2.2 geometry encoding and interpolation model * an extension model in support of application profiles * conformance requirements and test cases The adopted OpenGIS KML 2.2 Encoding Standard (OGC KML) is available at http://www.opengeospatial.org/standards/kml/. About the OGC The OGC(R) is an international consortium of more than 345 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available geospatial standards. OpenGIS(R) Standards support interoperable solutions that "geo-enable" the Web, wireless and location-based services, and mainstream IT. OGC Standards empower technology developers to make geospatial information and services accessible and useful with any application that needs to be geospatially enabled.
