The Open Geospatial Consortium (OGC®) has issued an addendum to its May 11 Request for Quotes/Call for Participation (RFQ/CFP) for the OGC Web Services, Phase 5 (OWS-5) Interoperability Initiative. OWS-5 is a testbed to advance OGC"s open geospatial interoperability framework. The addendum and the original RFQ/CFP are available at http://www.opengeospatial.org/standards/requests/43.

As described in the addendum, in response to sponsor requirements the OWS-5 initiative"s Agile Geography thread has been expanded to include two new work items. The new work items are titled "Federated Geo-synchronization Services" and "OWS Core + Extensions Experiment". In the Federated Geo-synchronization work, participants will help develop standard approaches to using GML application schemas such as GeoRSS GML and GML Simple Features Level 0 with Atom and the Atom Publishing Protocol. Atom addresses the syndication of Web content such as weblogs and news headlines to Web sites as well as directly to user agents. The OWS Core + Extensions work item involves participants implementing a more formal and modular approach to structuring OGC standards.

The RFQ/CFP includes details of these work items. Responses are due by October 5, 2007. If your organization is interested in participating, contact Raj Singh at rsingh@opengeospatial.org.

OWS testbeds are part of OGC"s Interoperability Program, a global, hands-on and collaborative prototyping program designed to rapidly develop, test and deliver proven candidate specifications into OGC"s Specification Program, where they are formalized for public release. In OGC"s Interoperability Initiatives, international teams of technology providers work together to solve specific geoprocessing interoperability problems posed by the Initiative"s sponsoring organizations.
