Sequences are a natural part of the world to be modelled in ontologies. Yet the Web Ontology Language, OWL, contains no specific support for ordering. It does, however, have constructs that can be used to model many aspects of sequences, albeit imperfectly. This paper demonstrates a design pattern for modeling order within OWL-DL. This allows us to use(More)

The relative rarity of this serotype and other epidemiologic evidence suggest that the organism was endemic in the institution for at least 3 years. Persistent carriers as well as ill and(More)
