Experience API (xAPI) Vocabulary & Semantic Interoperability Community Group
This group was closed on 2023-12-11.
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).

Companion Specification & Primer for xAPI Vocabularies

Companion Specification
and
Vocabulary Primer
is now available for public comment. This announcement comes nearly one year since the
Vocabulary Considerations for XAPI
white paper was published by ADL. Following the white paper, ADL facilitated by this W3C community-driven
xAPI Vocabulary Working Group
to investigate how to improve semantic interoperability for xAPI. These documents are applicable to anyone creating new vocabulary terms (Verbs or Activity Types) for xAPI. It is also applicable to any individuals or organizations developing applications for publishing, storing or retrieving vocabulary identifiers and definitions, or any other types of services that need to query the semantic meaning of xAPI vocabulary data. We are looking for community feedback on these documents before applying vocabulary-specific revisions to the
core xAPI Specification

W3C Membership
is not required to join a Community Group.
This is a community initiative. 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. W3C’s hosting of this group does not imply endorsement of the activities.
The group must now
