OGC Seeks Input on Next Version of Geography Markup Language

The Open Geospatial Consortium, Inc. (OGC®) is inviting the public to offer change requests for consideration by the OGC Technical Committee on a revision of the OpenGIS® Geography Markup Language (GML) Encoding Standard. GML defines a data encoding in XML for geographic data and a grammar to express models of such data using XML Schema.

GML has come into wide use since it was first adopted as an OGC standard in 2002. Implementations typically specify GML application schemas. GML is consistent with the OGC's entire open geospatial standards platform. GML is the standard that enables information communities and other standards organizations such as the Internet Engineering Task Force (IETF) and OASIS to insert geospatial components into their standards and be confident that their standards will be compatible with mainstream information infrastructure methods of conveying spatial/temporal information.

The current version of GML was approved last year and is also published as ISO 19136:2007 by the International Organization for Standardization (ISO). The OGC Technical Committee is reviewing the need for changes in the standard and wants to receive suggestions from the wider community. Change requests should be submitted by September19, 2008.

The OGC template for change requests is available at http://www.opengeospatial.org/standards/cr and must be sent to change-requests@opengeospatial.org
