-----------------------------------------------------------------------

6 July 2011. The Open Geospatial Consortium (OGC®) seeks public
comment on the candidate OGC “GeoSPARQL: A Geographic Query
Language for RDF Data” Standard. The candidate OGC GeoSPARQL
standard defines spatial extensions to the W3C's SPARQL protocol and
RDF query language.

SPARQL is a protocol and query language for the Semantic Web. SPARQL
is defined in terms of the W3C's RDF data model and will work for any
data source that can be mapped into RDF, which potentially includes
sources of geospatial data. The OGC GeoSPARQL standard supports
representing and querying geospatial data on the Semantic Web, and it
provides the foundational geospatial vocabulary for linked data
involving location. GeoSPARQL defines a vocabulary for representing
geospatial data in RDF, and it defines an extension to SPARQL for
processing geospatial data. This standard serves as a common target
for vendors to implement and provides rich functionality for building
geospatial applications.

GeoSPARQL follows a modular design. A core component defines top-level
RDFS/OWL classes for spatial objects. A geometry component defines
RDFS data types for serializing geometry data, RDFS/OWL classes for
geometry object types, geometry-related RDF properties, and
non-topological spatial query functions for geometry objects. A
geometry topology component defines topological query functions. A
topological vocabulary component defines RDF properties for asserting
topological relations between spatial objects, and a query rewrite
component defines rules for transforming a simple triple pattern that
tests a topological relation between two features into an equivalent
query involving concrete geometries and topological query functions.

The candidate OGC GeoSPARQL Standard documents are available for
review and comment at
http://www.opengeospatial.org/standards/requests/80.

The OGC is an international consortium of more than 415 companies,
government agencies, research organizations, and universities
participating in a consensus process to develop publicly available
geospatial standards. OGC Standards support interoperable solutions
that "geo-enable" the Web, wireless and location-based services, and
mainstream IT. OGC Standards empower technology developers to make
geospatial information and services accessible and useful with any
application that needs to be geospatially enabled. Visit the OGC
website at http://www.opengeospatial.org.
