Opportunities for Semantic Web knowledge representation to help XBRL

Semantic Web can offer XBRL: • Sophistication in knowledge representation (KR). E.g., expressiveness, nonmonotonic reasoning (conflict handling), interoperability, and performance optimization techniques. E.g., rule-based ontologies, rule-based business policies, rule-based analytics, expressive queries and views. o Key semantic rule standards today are based primarily on declarative logic programs (LP) and include: W3C Rule Interchange Format (RIF) [10] and OWL 2 RL (Rules Profile) [12]. The next steps of standardization, esp. of RIF, are likely to be highly influenced by the RuleML standards design [13] and the recent SILK approach [9]. ISO Common Logic [14] and OMG SBVR [15], based primarily on classical first-order logic (FOL), are relevant as well; so are SPARQL [11], SQL, and XQuery, which are based primarily on LP. • Related domain ontologies and knowledge bases. These may be broad or narrow in scope. • Directions for “virality”, to extend the set of applications, methods, and domains for XBRL by combining it with those for Semantic Web. E.g., in e-commerce, health care & life science, and business intelligence. E.g., semantic wikis [7].
