Community standards

A Community standard is an official position of the OGC endorsing a specification or standard developed external to the OGC. A Community standard is considered to be a normative standard by OGC membership and part of the OGC Standards Baseline. The key consideration for a Community standard is that there must be strong evidence of implementation. OGC does not take over the maintenance of the work, rather a Community standard is a “snapshot” of a mature standard for which the originator has either shared the Intellectual Property Rights with the OGC or granted unlimited free use of the Intellectual Property to all implementers.

Community standards can serve two purposes:

1. to bring de facto standards from the larger geospatial community to be a stable reference point that can normatively referenced by governments and other organizations; and
2. to bring new, but implemented, standards to the OGC to form the basis for further refinement and development of interoperability between other OGC standards.
