6 January 2015 — The W3C and the Open Geospatial Consortium (OGC) announced today a new collaboration to improve interoperability and integration of spatial data on the Web. Spatial data —describing geographic locations on the earth and natural and constructed features— enriches location-based consumer services, online maps, journalism, scientific research, government administration, the Internet of Things, and many other applications.
The membership of the Open Geospatial Consortium (OGC®) seeks public comment on the candidate OGC KML 2.3 Standard.
KML is an XML grammar used to encode representations of places and objects for display in an earth browser, such as a 3D virtual globe, 2D web browser application, or 2D mobile application. KML can be used to accomplish various map and Earth image functions, such as: annotate places, specify icons and labels to identify geographic locations, create different camera positions to define unique views for KML features, define image overlays to attach to map views, and define the location and orientation of textured 3D objects.
The main KML enhancements provided in version 2.3 are:
Addition of a new feature, KML Tour, which enables a user to specify aspects of a controlled virtual flight through a series of geographic locations, including speed, mode of flight (smooth or bounce), sound tracks and how KML features are updated throughout the tour.
Addition of new geometries: Track and MultiTrack. A KML Track can capture and display the path and other aspects of a moving object over a specified period of time.
Enhancements to KML’s Extension Mechanism, allowing for the direct use of XML content from third-party schemas. KML 2.3 is now based on XML Schema 1.1 enabling Aauthors of KML Application Profile extensions are now able to experimentally add foreign element and attribute content interleaved among existing KML elements.
The documents for the candidate OGC KML 2.3 Standard are available for review and comment below. Comments are due by 18 January, 2015.
Comments can be submitted to a dedicated email reflector for a thirty day period ending on the "Close request date" listed above, Comments received will be consolidated and reviewed by OGC members for incorporation into the document. Please submit your comments using the following link: requests [at] lists.opengeospatial.org (Click here to submit comments) The link provided above should include a standard template in the message body.

Dr. Robert Moses, president and CEO of PCI Geomatics, was an image processing and GIS pioneer whose generous support during the first “evangelizing” period of OGC’s existence made it possible for founder David Schell and a small band of enthusiasts to organize support for the consortium.
Cliff Kottman was one of the visionaries who helped conceive the Open Geospatial Consortium in the early 1990s. He was brilliant, creative, and deeply analytic as well as being a wise and engaging teacher. Cliff served as OGC's Vice President for Technology Development and Chief Scientist from 1997 until 2003.
This OGC® IndoorGML standard specifies an open data model and XML schema for indoor spatial information. IndoorGML is an application schema of OGC® GML 3.2.1. While there are several 3D building modelling standards such as CityGML, KML, and IFC, which deal with interior space of buildings from geometric, cartographic, and semantic viewpoints, IndoorGML intentionally focuses on modelling indoor spaces for navigation purposes.
