The Open Geospatial Consortium (OGC(r)) 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. GeoSPARQL provides the
foundational geospatial vocabulary for linked data involving location
and defines extensions 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 below.
