22. Making Location Count... The OGC has not generally focused on geosemantics and interoperability other than a few targeted projects –Geosemantics Interoperability Experiment –Geosemantics Domain Working Group –A thread in some OGC IP Activities –OGC Naming Authority –GeoSPARQL But many member organizations are dealing with semantics and geosemantics OGC Semantics Work

23. Making Location Count... Not Easy, not Perferct "The man who insists on seeing with perfect clearness before he decides, never decides." –Henri-Frédéric Amiel The real crux of dealing with semantics in the geo context!

24. Making Location Count... Without vocabularies, we cannot communicate And forget “real” content interoperability For the first 3 years of OGC existence, focus was on the Abstract Model, semantics, and vocabularies –What is a coordinate? –What is a Point? –What is a feature?

25. Making Location Count... A process that seems to work Vitally necessary for domain community information experts to collaborate and define volcabular(ies) and information models!

26. Making Location Count... And then Encode the information model in a community accessible, consenus approved encoding Such as CityGML and GeoSciML

27. Making Location Count... Case 1 This collaboration can happen external to the OGC and then the work brought into the OGC The proposed Hydrology work is an example of this use case

28. Making Location Count... Case 2 This collaboration can happen external to the OGC and stay external to the OGC and approved as a standard in that domain’s appropriate accreditation body. For example GeoSciML -> The Commission for the Management and Application of Geoscience Information

32. 32 Making Location Count... OGC Naming Authority In April of 2008, the IETF/IESG approved the OGC NID/URN proposal. The OGC urn designation is registered with IANA and is documented in RFC 5165 (http://www.faqs.org/rfcs/rfc5165.html ). (http://www.faqs.org/rfcs/rfc5165.htm A requirement for having a registered urn is that the OGC must have a naming authority. This authority is responsible for reviewing and registering any proposed OGC urn usage. At the June 2008 Potsdam meetings, the TC and the PC formally approved constituting the OGC Naming Authority (OGCNA) as a subgroup of the Technical Committee.
