For over ten years, the Open Geospatial Consortium has been defining standards for the interoperability of spatial data and services. Early on, OGC bought into what has recently been called "Web 2.0"--XML-based web services designed to be chained together across companies to create powerful, "value-added" applications that no single information provider might have seen fit to build on their own. In the last few years OGC has seen wide use of its APIs to build services in the "big" science, engineering, and government sectors, but the commercial sector and the mainstream web community is just beginning to become aware of the offerings.

This talk will briefly survey OGC's existing APIs for sharing maps and spatial data via web services, then describe the emerging focus areas in geospatial digital rights management and sensor data sharing architectures. Finally, these disparate threads will be tied together to paint a picture of how government and commercial databases, dynamically sensed information (environmental monitoring devices, security cameras, etc.), and personal repositories (travel journals, GPS logs, etc.) will weave together in the future to create the Geospatial Web.
