Profiling data exchange standards using vocabularies

This presentation will demonstrate techniques for declaring and exploiting the use of controlled vocabularies using JSON schemas for data exchange, in applications such as the OGC API-Features service interface (and any other OpenAPI implementations.) The approach takes a modular approach with tools to support composition to match reused schema elements to reusable JSON-LD contexts, allowing implementations to simplify profiling by adding additional constraints, such as vocabulary usage, to specific sub-elements of an overall application schema. The approach uses open source tools based on the "OGC Building Blocks" model - part of the full-spectrum interoperability resource now known as the OGC Rainbow.
