Specification for Activity Stream 2.0
See working document Activity Streams - Example Change Documents for Authoritative Data.
Compatible with JSON-LD, but has its own media-type.
...
Many of the changes we will make are covered by the activity types in the spec. May need to add custom types for some (e.g. label change).
If done on a triple by triple basis, this might look like...
