With your support, the Experience API (xAPI) Vocabulary & Semantic Interoperability Community Group has been launched:
  http://www.w3.org/community/xapivocabulary/

This group was originally proposed on 2015-07-15
by Jason Haag. The following people supported its
creation: 
      Jason Haag
      Avron Barr
      Jason Lewis
      Russell Duhon
      Ingo Dahn
  
To join the group, please use:

Please note that supporting a group is different from joining
a group. Supporters must also enroll if they wish to participate.

--------------------
Currently Experience API (xAPI) mostly focuses on providing “structural”
interoperability via JavaScript Object Notation Language (JSON).
Structural interoperability defines the syntax of the data exchange and
ensures the data exchanged between systems can be interpreted at the
data field level. In comparison, semantic interoperability leverages the
structural interoperability of the data exchange, but provides a
vocabulary so other systems and consumers can also interpret the data.
Analytics produced by xAPI statements would benefit from more consistent
and semantic approaches to describing domain-specific verbs. The xAPI
specification recommends implementers to adopt community-defined
vocabularies, but the only current guidance is to provide very basic, 
human-readable identifier metadata (e.g., literal string name(display),
description). The main objective of the Vocabulary and Semantic
Interoperability Working Group (WG) is to research machine-readable,
semantic technologies (e.g., RDF, JSON-LD) in order to produce guidance
for Communities of Practice (CoPs) on creating, publishing, or managing
controlled vocabulary datasets (e.g., verbs).
