Vocabulary - Fwd: ActivityStreams Schema: Hierarchy of Types

Hi,

Owen Shepherd have shared this proposal with Social WG. Can we provide
some feedback based on analysis of submitted Use Cases? I would also
like to ask if someone could help with compiling side by side comparison
to Microformats2 and Schema.org?

* http://schema.org/docs/full.html

Thank you!

As I work on the proposed spec which I'll be submitting imminently as a
basis for our social API, it occurs to me that we really ought to (A)
work out our base types (as Evan brought up earlier this week), and (B)
work our our classification system.

I figure that we have three broad groups of Objects:

  * "Actors" - people, robots, etc. The "users" of our social system,
    whether sentient or not.
  * "Content objects" - notes, articles, videos, etc. These are
    "passive" objects - they can only be created and acted on by the
    previous
      o With "Media" as a subclass for things like videos and audio,
        which share a common property set
  * "Other" - Things like groups, which don't really fall into either of
    the two previous categories

This gives us an ontology somewhat like this (where each indent level
implies a subclass relationship)

  * as:Object - Base type
      o as:Actor?
        A "producer"/"consumer" in AS ontology
          + as:Person - A human being
          + Others for "bots"?
      o as:<Something> (Content objects; This is kind of like what
        Tantek would call a post)
        Can have things like comments, list of people who like, etc
          + as:Note - shortform text (e.g. a tweet)
          + as:Article - longform text
          + as:Media(Object?) - Various types of multimedia (all share
            common properties)
              # as:Audio
              # as:Video
              # as:Image
              # ...
          + as:Location
          + as:Collection
          + ...
      o as:Group

This then gives us a basis for declaring common properties (e.g. a
Person doesn't have comments, but all content objects do)

Thoughts?

Owen
