checking and data validation Dacura front-end – Gives a convenient user-

interface to DQS

The main ideas

Schema and Instance – OWL ontology gives us a schema, we then treat the instance data as we would “rows in an SQL table”

We use prolog as it is a flexible recursive query language which enables the use of libraries of predicates.

We intentionally misinterpret OWL as a constraint language.
