OGC API – EDR – Part 2: Publish-Subscribe Workflow

OGC API Standards specify Web based capabilities that are typically based on polling for collection resource updates (new features, records, items, coverages, maps, etc.). Depending on a collection’s temporal resolution or frequency of updates, an event-driven / Publish-Subscribe architecture provides a timely, efficient and low latency approach for the delivery of data updates or notifications of updates. The OGC API — Environmental Data Retrieval — Part 2: Publish-Subscribe Workflow Standard provides recommendations on applying Publish-Subscribe architectural patterns to implementations of one or more OGC APIs.
