Table 7.

A comparison of popular knowledge resources, typically used in TM for the life sciences

Name	Type	Domain	Size	Format	License
Uniprota	Knowledge base	Proteomics	63 million sequences	Own, RDF, FASTA	CC
UMLSb	Thesaurus	Biomedical	3.2 million concepts	Own	Proprietary
Gene Ontologyc	Ontology	Genetics	44 000 terms	OBO	CC
Agrovocd	Thesaurus	Agriculture	32 000 concepts	RDF	CC
HPOe	Vocabulary	Human phenotype	10 000 terms	OBO, OWL, RDF	Free to use
CNOf	Vocabulary	Neuroscience	395 classes	OWL, RDF	CC
CAROg	Ontology	Anatomy	96 classes	OBO, OWL	Unspecified

These resources differ in terms of type, domain and intended use. These differences make size difficult to compare as different resources have different base elements. Nonetheless, we have presented the table in an approximate order of size from largest to smallest.
