Porifera Ontology

KGXBioPortal ontologyvunknown
Visibility: Public

A KGX transformation of the BioPortal ontology Porifera Ontology (PORO), 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 PORO_nodes.tsv and PORO_edges.tsv. The full graph contains PORO_full_nodes.tsv and PORO_full_edges.tsv: this ontology plus the 6 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.

Imports 6 · 6 in KG‑Bioportal

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.
