Standardizing Legal Content with OWL and RDF
Wolters Kluwer is one of the largest legal publishers in the world. Its various publishing units use a multitude of different formats to mark up what is effectively similar content. We describe a common content architecture based on OWL, RDF and XHTML that is used to build a standard representation of legal content, allowing publishable assets to be integrated across the enterprise. This architecture is governed by an OWL ontology that models the (occasionally complex) behaviour of legal documents and acts as a domain model of common legal metadata. How do OWL and RDF scale up to real-world publishing? We describe practical issues in producing and validating RDF on an industrial scale; in performance management; in handling fragmented ontologies; and the challenge of using RDF in a performant XSLT pipeline.
