The CCDB dictionary provides definitions for
terms and concepts used in the CCDB. Where possible, the CCDB maps
these concepts to unique identifiers contained in the Unified Medical
Language System (
UMLS)
or other appropriate ontologies. Identifiers beginning with "BF" refer
to the Bonfire, a collection of knowledge sources developed and maintained
by the Biomedical
Informatics Research Network (BIRN) project. More information
about Bonfire IDs can be found
here.
