A definition of types in an information system is given from ld abstractions through data constructs, schema and definitions to physical data values. Category theory suggests tha...
Mathematical software libraries provide many computational services. Mathematical operators properties can be used to combine several services in order to provide more complex one...
This paper presents a specifically database-inspired approach (called DOGMA) for engineering formal ontologies, implemented as shared resources used to express agreed formal semant...
RDF-based P2P networks have a number of advantages compared with simpler P2P networks such as Napster, Gnutella or with approaches based on distributed indices such as CAN and CHO...
