12. Helping the World to Communicate Geographically Copyright © 2009, Open Geospatial Consortium, Inc., OGC’s Approach for Advancing Interoperability Interoperability Program (IP ) - a global, innovative, hands-on prototyping and testing program designed to accelerate interface development and validation, and bring interoperability to the market Specification Development Program – Consensus processes similar to other Industry consortia (World Wide Web Consortium, OMA, OMG, etc.). Outreach and Community Adoption Program – education and training, encourage take up of OGC specifications, business development, communications programs Rapid Interface Development Standards Setting Market Adoption

13. Helping the World to Communicate Geographically Copyright © 2009, Open Geospatial Consortium, Inc. Interoperability Program – Major Benefits To Sponsors Ability to Determine Market Interest -- OGC’s RFQ / RFT process validates the willingness of industry to address specific interoperability issues requiring new standards Rapid prototype development yields workable interface specifications in 4-6 months vice years for traditional standards processes Vendors test, validate and demonstrate interface integrity by implementing candidate specifications in their products (reduces the risk that a proposed standard will not perform as intended) Accelerated process encourages rapid time to market for Standards- based solutions –OGC member vendors are typically early adopters of new specifications 13

14. Helping the World to Communicate Geographically OGC Interoperability Program Initiative Return on Investment Participants in OGC testbeds and pilot initiatives contribute more in in-kind contributions (labor, software, infrastructure etc.) than is provided in Sponsor funding. For every one Euro or Dollar in sponsorship funding, the following initiatives have yielded: –Web Mapping Testbed I4 times –Open location Services1.5 times –OGC Web Services 3 Testbed3 times –OGC Web Services 4 Testbed3.5 times –OGC Web Services 5 Testbed3.3 times Why? Vendors want early influence in specification development, early skill building, visibility, and opportunity for early market deployment of standards.
