The goal for the OGC GeoSPARQL standard is to support representing and querying geospatial data on the Semantic Web. GeoSPARQL defines a vocabulary for representing geospatial data in RDF, and it defines an extension to the SPARQL query language for processing geospatial data.

The preliminary work on a draft of the candidate standard has been completed. As soon as possible, the SWG hopes to approve a 30 day Request for Comment for the candidate standard to the OGC Technical Committee and to the public. The resulting comments will guide the GeoSPARQL SWG in the finalization of the implementation standrrd, hopefully to be ready for a final standardization vote by OGC before the end of 2011.

OGC® PUCK Protocol Standard

This standard defines a protocol for RS232 and Ethernet connected instruments. PUCK addresses installation and configuration challenges for sensors by defining a standard instrument protocol to store and automatically retrieve metadata and other information from the instrument device itself.

Most sensor networks require careful manual installation and configuration by technicians to assure that software components are properly associated with the physical instruments that they represent. Instrument driver software, configuration files, and metadata describing the instrument and its ...

Filter Encoding

This jointly developed OGC and ISO TC/211 International Standard describes an XML and KVP encoding of a system neutral syntax for expressing projections, selection and sorting clauses collectively called a query expression. These components are modular and intended to be used together or individually by other standards which reference this International Standard.

Metadata DWG

The Metadata DWG addresses issues related to how metadata must be specified in OpenGIS Specifications to fully enable certain services in the OpenGIS Service Architecture. Maintains close correspondence between ISO TC/211 metadata standard and OpenGIS Specification's handling of metadata.
