Geolinked Data Access Service

Endorsed Standard
Description
 

The Geolinked Data Access Service allows a client to retrieve a set of geolinked data. Organizations that wish to distribute attribute data without the accompanying geospatial data can do so via this service.

Geolinked data returned from a request to this service can be merged with a set of geospatial data using a geolinking service.

Other Info
 

There is no capability in the existing specification to restrict the volume of data that is returned in response to a query. Subsequent versions of this service may be capable of restricting queries based on a set of spatial and non-spatial constraints.

Future versions of this service may be based on a simplified version of the Web Feature Service. GML may be an optional output format supported in future.

This specification is currently a Discussion Paper at OGC. It was the focus of an OGC interoperability in 2007.
