Vocabulary Of Attribution and Governance

"VOAG stands for 'Vocabulary Of Attribution and Governance'. The ontology is intended to specify licensing, attribution, provenance and governance of an ontology. VOAG captures many common license types and their restrictions. Where a license requires attribution, VOAG provides resources that allow the attribution should be made. Provenance is defined in terms of source and pedigree. A miminal model of governance is provided based on how issues, releases and changes are managed.

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."


"XKOS leverages the Simple Knowledge Organization System (SKOS) for managing statistical classifications and concept management systems, since SKOS is widely used. LOD is used to create Web artifacts that machines can interpret, so publishing machine-readable statistical classifications and other concept management systems as SKOS instances is desired. The XKOS developers found that SKOS was insufficient for the problem. No aspect of SKOS was found to be wrong, just incomplete. Therefore, an extension to SKOS, called XKOS, is proposed.
