OGC publishes many different types of documents for public for use, review and comment. These are NOT official positions of the OGC, and they are not standards and do not have the same level of OGC endorsement.
These documents are user guides created as a deliverable of an initiative from the OGC Innovation Program (formerly OGC Interoperability Program). They are not OGC standards. They are not official positions of the OGC membership. There may be additional valid approaches beyond what is described in these user guides.
