OGC API - Joins

OGC API standards define modular API building blocks to spatially enable Web APIs in a consistent way. OpenAPI is used to define the reusable API building blocks with responses in JSON and HTML.

The OGC API family of standards is organized by resource type. The draft OGC API – Joins standard specifies a Web API that allows data to be joined from inputted data files either with feature collections that are available on the server or directly with other inputted files. OGC API – Joins also defines functionalities for viewing general metadata on the service implementation, metadata and key values on the feature collections and functionalities for accessing and deleting the created joins.
