Definition (Simple RDF Interpretation). A simple interpretation of an RDF vocabulary of IRIs and literals, V = ? ∪ ?, is a sextuple (IR, IP, IEXT, IS, IL, LV), where IR = ∅ the domain of interpretation I, IP the set of properties of interpretation I, IEXT : IP → P(IR × IR), IS : ? → IR ∪ IP, IL a mapping from types literals in V into IR, and LV ⊆ IR the set of literal values.
Simple RDF interpretations only provide the semantics of IRIs and typed literals.
