OGC Schema Repositories

OGC develops many information models, usually in the form of XML Schema documents. The general process for disseminating a model is to publish a specification (or standard) document, and publish the XML schema to a schema repository. Based upon the status of specification or documentation, the schemas will be posted to one of several repositories.

This site provides links to those resources and also offers a place to collaboratively develop new profiles.

http://schemas.opengis.net - the official OGC XML schema repository, this is used for Adopted Technology (Implementation Standards), such as OGC's GML, SensorML, or WMS. These schemas are maintained by version numbering (x.x.x).

http://bp.schemas.opengis.net - repository for XML schema documents related to OGC Best Practice documents. Best Practices Documents are an official position of the OGC and thus represent an endorsement of the content of the paper. These schemas are maintained by OGC Document Numbers (YY-xxx).

http://dp.schemas.opengis.net - repository for XML schema documents related to OGC Discussion Papers documents. Discussion papers are not intended to be targets of acquisition descriptions. These papers do not represent the official position of the Open Geospatial Consortium nor of the OGC Technical Committee. These schemas are maintained by OGC Document Numbers (YY-xxx).

http://www.ogcnetwork.net/schemas - repository for experimental XML instance and schema documents. Documents posted here do not represent an official positition of the OGC. This repository is for the convenience of developers in the OGC community, and are not necessarily on track for adoption as a standard. The OGC community also manages these schemas.
