Web Of Trust

"RDF documents can make any number of statements. Without some kind of signature or other similar verification mechanism, there is no way to understand who made these statements. One way to document who made a set of statements is via the use of Digital Signatures: signing a document using Public Key Cryptography. The WOT, or Web Of Trust, schema is designed to facilitate the use of Public Key Cryptography tools such as PGP or GPG to sign RDF documents and document these signatures."

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.
