ClioPatria + SWI Prolog for triple store DQS – a plugin for ClioPatria providing ontology
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.
