DIAN overview. (Left) computer-aided human curation process for the assignment of SWISS-PROT sequences to the Protein Function and Cellular Role ontologies; (right) application of ontologies to organize biological annotation databases. Multiple ontologies, each representing a body of biological knowledge, are stored in the DIAN database. Individual source records stored in biological sequence and structure annotation databases are associated with one or more ontologies via domain-based and/or vocabulary-based mapping, such that they can be queried simultaneously across multiple ontologies. (GB) GenBank; (GP) GenPept; (SP) SWISS-PROT; (DB) database.
