Standards will be a key driver for model-based digital realities. Encoding standards and interface standards make data and online processing resources more widely useful and thus more valuable. The OGC CityGML Encoding Standard, for example, will be important for semantically rich 3D models, and the OGC Web Processing Service Standard will be important for linking different modeling processes.

The IndoorGML Standards Working Group will hold its first meeting at the OGC Technical Committee meeting in Austin, TX, March 19-27. IndoorGML will be important for indoor navigation and the integration of diverse indoor location determination technologies.
