OGC API - Common

OGC API - Common is a multi-part draft that documents the set of common practices and shared requirements that have emerged from the development of Resource Oriented Architectures and Web APIs within the OGC. The specification serves as a common foundation upon which all OGC APIs will be built. As such, the OGC API - Common standard serves as the "OWS Common" standard for resource-oriented OGC APIs. Consistent with the architecture of the Web, this specification uses a resource architecture that conforms to principles of Representational State Transfer (REST). The specification establishes a common pattern that is based on OpenAPI. In addition to identifying core resources, the OGC API - Common specification goes on to specify HTTP status codes that may be supported by an OGC API, as well as how to handle a coordinate reference system (CRS), web caching, and encodings. The specification also describes how to handle common parameters such as bounding boxes and date-time constraints.
