6.1 Introduction

OGCs Interoperability Program is a global, hands-on and collaborative prototyping program designed to rapidly develop, test and deliver proven candidate specifications into OGCs Specification Program, where they are formalized for public release. In OGCs Interoperability Initiatives, an international team of technology providers work together to solve specific geo-processing interoperability problems posed by the initiatives sponsoring organizations. OGC Interoperability Initiatives include test beds, pilot projects, interoperability experiments, and interoperability support services - all designed to encourage rapid development, testing, validation and adoption of open, consensus based standards specifications. In the fall of 2005, the OGC issued a call for sponsors for an OGC OWS-4 Interoperability initiative testbed activity to advance OGCs open framework for interoperability in the geospatial industry. Three meetings were conducted with potential OWS-4 sponsors to review the OGC technical baseline, to discuss OWS 3 results, and to identify OWS 4 requirements. Sponsors have expressed keen interest in advancing standards for sensor webs, geospatial digital rights management, geospatial semantics and knowledge management. After analyzing the sponsors input, the OGC Interoperability Team recommended to the sponsors that the content of the OWS-4 initiative be organized around the following 7 threads: • Sensor Web Enablement SWE • Geo Processing Workflow GPW • Geo Decision Support GeoDSS • Geo-Digital Rights Management GeoDRM • CAD GIS BIM • OGC Location Services OpenLS • Compliance Testing CITE The following companies sponsored this initiative: NGA, NTA, GeoConnections, NASA, ORNL, LMCO, BAE, GSA, Ordnance Survey, NATO C3, TeleAtlas.
