2006-06-13 - 2006-12-15: OGC OWS-4

From Datafedwiki

OGC’s Interoperability Program is 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, an international team of technology providers’ work together to solve specific geo-processing interoperability problems posed by the initiative’s 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 OGC’s 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: 1) Sensor Web Enablement (SWE) 2) Geo Processing Workflow (GPW) 3) Geo Decision Support (GeoDSS) 4) Geo-Digital Rights Management (GeoDRM) 5) CAD / GIS / BIM 6) OGC Location Services (OpenLS) 7) Compliance Testing (CITE)

DataFed is involved in developing components for two of these threads:

Sensor Web Enablement (SWE) The Sensor Web subtask will continue to mature the existing set of SWE work items to enable the federation of sensors, platforms and management infrastructure into a single sensor enterprise. This enterprise will enable the discovery and tasking of sensors as well as the delivery of sensor measurements regardless of sensor type and controlling organization. The ultimate vision is of a sensor market place where users can identify, evaluate, select and request a sensor collection regardless of sensor type, platform or owner. Emphasis for SWE during this phase of the OWS project will be on: • Leveraging results of OWS-3 and SAS IE initiatives to refine, extend and integrate those specifications and implementations. • Developing examples of SWE Information Model schema elements (i.e., O&M, SensorML, TransducerML and SWE Common) for specific classes and uses of observation offers, phenomena, sensor systems, processes and transducers. • Harmonizing SWE concepts and specifications with other OGC specifications and initiatives. • Harmonizing SWE concepts and specifications with other complementary initiatives moving forward by other organizations, including IEEE, OASIS and US Government agencies and programs. • Demonstrating support for realistic operational scenarios per the SWE Enterprise Viewpoint and Use Cases. In OWS-4, emphasis of interoperability engineering activities for the SWE thread will be on integration and demonstration of physical sensors and simulators within a realistic operating environment. In addition, progress is expected on enhancements to the SWE specifications as described in the “Future work” clauses of the respective baseline documents.

Geo Processing Workflow (GPW) The Geo-Processing Workflow (GPW) thread will develop and demonstrate how to interconnect geo-processes through publish-find-bind and service chaining to meet workflow requirements. The result will be the creation of valued-added enterprise systems that demonstrate the power of interoperability and service-oriented architectures. The OWS-4 GPW thread brings together developments from several previous initiatives. The planned activities for GPW: • UML and GML3.2 application schema development • Producer to Customer Production Workflow • SWE Geo-processing Workflow • Catalog Services for OWS-4
