s Service (CAS) registry number (7439-97-6), "raw" CAS number (dashes removed---7439976), and common name ("quicksilver "). Within an ontology, each class has one or more slots, where each slot has a conceptual domain name with a canonical value domain over which all agents communicate when referring to that slot. This mapping problem has several manifestations, which we relate roughly in the order they have been addressed in the literature (insofar as they are addressed at all): ffl Traditional: Mapping between schemas can take place by imposing a view on that information and/or defining functions to translate the data from one value domain to another, as is currently done in relational databases, e.g., [9]. This type of mapping provides little support for semantics, but rather relies on the structure of the data. ffl Ontology-based: A common ontology is defined with well-specified semantics for the concepts it describes. Mapping between a schema and an ontology is done on a semantic...
