te:TrustEnvelope a rdfs:Class, skos:Concept ;
    rdfs:isDefinedBy te: ;
    rdfs:label "Trust Envelope"@en ;
    skos:definition "A Trust Envelope is a unique data document, timestamped and digitally signed by a sender, that represents a singular act of associating a data unit with context specific to an actual or proposed processing of the data unit by the recipient."@en ;
    rdfs:comment "The context's history metadata consists of a relevant subset of provenance claims pertaining to the data unit; the context's destiny metadata consists of instantiated usage policies capturing the sender's agreement or disagreement with relevant processing involving the data unit. A Trust Envelope thereby forms a two-sided evidence mechanism by which the sender can substantiate towards the recipient a degree of the data unit's relevance and correctness, and the recipient can demonstrate towards third parties the fulfillment of preconditions to a certain processing of the data unit."@en .

te:DataProvenance a rdfs:Class, skos:Concept ;
    rdfs:isDefinedBy te: ;
    rdfs:label "Data Provenance"@en ;
    skos:definition "Contextual information that captures the origin and history of data, including its source entity, entity providing the data, and issuance time."@en .

te:PolicyProvenance a rdfs:Class, skos:Concept ;
    rdfs:isDefinedBy te: ;
    rdfs:label "Policy Provenance"@en ;
    skos:definition "Contextual information that captures the origin and history of a policy, including entities that have usage rights over the data unit, entity that will receive the data unit, and issuance time."@en .
