FOSS4G 2022 general tracks

The OGC APIs are a fresh take at doing geo-spatial APIs, based on WEB API concepts and modern formats, including:

Small core with basic functionality, extra functionality provided by extensions
OpenAPI/RESTful based
JSON first, while still allowing to provide data in other formats
No mandate to publish schemas for data
Improved support for data tiles (e.g., vector tiles)
Specialized APIs in addition to general ones (e.g., DAPA vs OGC API - Processes)
Full blown services, building blocks, and ease of extensibility

This presentation will provide an introduction to various OGC APIs and extensions, such as Features, Styles, Maps and Tiles, DAPA, STAC and CQL2 filtering.
While some have reached a final release, most are in draft: we will discuss their trajectory towards official status, as well as how good the GeoServer implementation is tracking them, and show examples based on the GeoServer HTML representation of the various resources.
