Hola :)

Yes, JSON-LD based Activity Streams 2.0 make two First Public Working
Drafts which we work on in Social WG, latest versions:
* http://www.w3.org/TR/2015/WD-activitystreams-core-20150129/
* http://www.w3.org/TR/2015/WD-activitystreams-vocabulary-20150129/

Github repo: https://github.com/jasnell/w3c-socialwg-activitystreams/issues

BTW currently we work on HTTP API and collect requirements as User Stories
* https://www.w3.org/wiki/Socialwg/Social_API/User_stories

I could happily propose including Badges use cases among other collected
in Social IG, Use Case TF
* https://www.w3.org/wiki/Socialig/Use_Case_TF

Also just yesterday I took action in Social IG to discuss with
Credentials CG social profile requirements, will follow up on it shortly!
