xAPI Controlled Vocabulary Ontology

"XAPI vocabularies are created and shared by Communities of Practice (CoPs) to help facilitate the reuse of Verbs and Activity Types. This schema was designed to enhance the semantic interoperability of xAPI by encouraging the adoption of RDF principles and publishing practices. This document defines a schema and provides descriptions of each of the classes and properties that are recommended for use when classifying and publishing datasets as RDF. By using RDF to describe xAPI vocabulary datasets, CoPs can increase discoverability and enable applications to easily consume metadata from multiple sources. Representing xAPI vocabulary datasets as RDF also further enables decentralized publishing of Verbs and Activity Types and can facilitate an open federated dataset search capability across applications, platforms, and CoPs."
