Q&A: Q&A Session for Webinar II: SPARQL for Business Rules and Constraint Checking: Introducing SPIN*

Semantic Web modeling languages like OWL offer a standard way to define domain concepts and their relationships. This alone, however, can’t fully address the need for describing executable behavior. Using the domain models for data validation, transformation and other application specific reasoning typically requires expressivity of rule languages. In this webinar we show how to use SPARQL to define efficient business rules and constraint checks that will work with any RDF database.

This webinar will:

  • Demonstrate the use of SPARQL and SPIN for tasks such as unit conversion, computer games, and executable domain-specific languages.
  • Discuss the advantages of combining best practices from the object oriented world with the flexibility of the Semantic Web languages.
  • Show how to define new SPARQL functions and reusable query templates

(SPIN = SPARQL Inferencing Notation; see Introducing SPIN (SPARQL Inferencing Notation)  and/or http://spinrdf.org/)
