This paper presents a mapping solution from ERDF(S) to Take vocabulary. The work is related to an investigation of integrating ERDF Derivation Rules into Take inference engine. Some steps are required to finalize this task: a mapping between ERDF(S) and Take vocabulary, integration of ERDF knowledge base in Take, and empowering Take inference engine to deal with both Closed World Assumption and Open World Assumption, specifically with Open and Closed predicates and two types of negation: strong negation and weak negation.
