QUDT

A KGX transformation of the BioPortal ontology Quantities, Units, Dimensions, and Types Ontology (QUDT), 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.

The base graph contains QUDT_nodes.tsv and QUDT_edges.tsv. The full graph contains QUDT_full_nodes.tsv and QUDT_full_edges.tsv: this ontology plus the 5 it imports (and their imports in turn), merged by ROBOT. Use it when the imported terms matter; the base graph merges more cleanly with other graphs. Releases are incremental, so each link points at whichever release most recently rebuilt this ontology.

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.
