Content Ontology Design Patterns as practical building blocks for web ontologies

In this paper we present how to extract and describe emerging content ontology design patterns, and how to compose, specialize and expand them for ontology design, with particular focus on Semantic Web technologies. We exemplify the described techniques with respect to the extraction of two content ontology design patterns from the DOLCE+DnS Ultra Lite ontology, and by showing the design of a simplified ontology for the music industry domain.
