Description:

Currently we have Activity Streams Vocabulary which includes Core Classes and Extended Classes together with big number of properties
* http://www.w3.org/TR/activitystreams-vocabulary/

We also have Microformats Vocabulary, heavily used by IndieWebCamp community and various other publishers
* http://microformats.org/wiki/microformats2

Also early work on mapping from Microformats Vocabulary to AS2.0 Vocabulary
* https://www.w3.org/wiki/Activity_Streams/Microformats_Mapping
As of now not included among other mappings in AS2.0 OWL ontology, which already includes various mappings to PROV
* http://www.w3.org/TR/activitystreams-vocabulary/#non-normative-ontology-definition

Besides that examples in AS2.0 Core spec, showing possible Microformats HTML serializations also use Microformats Vocabulary terms
* http://www.w3.org/Social/track/actions/34
* https://www.w3.org/wiki/Socialwg/Social_syntax

On top of that W3C currently negotiates with schema.org about using defined there vocabulary terms as formal and normative dependencies
* http://schema.org/docs/full.html

Schema.org also recently proposed extension mechanism which also allows hosting vocabulary on domains other then schema.org
* https://lists.w3.org/Archives/Public/public-vocabs/2015Feb/0052.html

JSON-LD context provides elegant way to map simple names intended for human readability to any URI. This gives big degree of flexibility in which URIs we choose to use. In theory, Activity Streams 'Person' could even map to h-card from Microformats Vocabulary if it provides stable URIs

This issue acts as reference point for tracking our progress on improving current state of things.
