The OGC Standards Baseline consists of the OGC standards for interfaces, encodings, profiles, application schemas, and best practice documents. The OGC Reference Model (ORM) describes these standards and the relationships between them and related ISO standards. The ORM provides an overview of OGC standards and serves as a useful resource for defining architectures for specific applications.
Most of the OGC standards developed in recent years are standards for the Web services environment, and these standards are collectively referred to as OGC Web Services (OWS). Some of these are “OGC standards” and others are publicly available “Discussion Papers”, “Requests” and “Recommendation Papers”.
