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
5. 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.
