Traditional Chinese Drug Ontology

KGXBioPortal ontologyv0.05
Visibility: Public

A KGX transformation of the BioPortal ontology Traditional Chinese Drug Ontology (TCDO), produced by KG‑Bioportal. Nodes are ontology classes; edges are the relations between them. The base graph is the ontology on its own, imports stripped; the full graph, where built, has the import closure merged in.

Full graph not built (unresolvable_imports)

At least one of this ontology's imports could not be fetched (a dead, moved, or unreachable URL), so ROBOT could not merge the import closure. The base graph is unaffected.

The base graph contains TCDO_nodes.tsv and TCDO_edges.tsv. Releases are incremental, so each link points at whichever release most recently rebuilt this ontology.

Imports 6

What this ontology pulls in through owl:imports. An import that is itself a BioPortal ontology links to its page here; a module of one links to the ontology it belongs to; anything else links out, or is named by its namespace when it is not a web address. The base graph leaves all of these out; the full graph, where built, has them merged in.
