OGC API – Environmental Data Retrieval – Part 2: Publish-Subscribe Workflow

This standard defines building blocks that can be assembled to implement Publish-Subscribe workflows (discovery, topic structure, encoding) as part of OGC API — Environmental Data Retrieval — Part 1: Core. A topic structure is the structured information that a publisher makes available to allow subscribers to choose information of interest to them.

Overview

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.
