I just watched a recent OGC webinar recording. It clearly laid out the relationship from the old OGC OWS services to the new OGC API standards as shown in the image below:

My question is: How do all of the ArcGIS Server services fit into this diagram? We publish map services, feature services, image services, geoprocessing services, and geocoding services. Would it look like this?

Please take a copy of the image and correct my mistakes.
Thanks,
Bernie.
