Psychometric Ontology of Experiences and Measures

KGXBioPortal ontologyv1.0
Visibility: Public

A KGX transformation of the BioPortal ontology Psychometric Ontology of Experiences and Measures (POEM), 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 POEM_nodes.tsv and POEM_edges.tsv. The full graph contains POEM_full_nodes.tsv and POEM_full_edges.tsv: this ontology plus the 1 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 1

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.

8inherits from a root class placed by review

8 of these nodes inherit a category from 3 root classes reviewed by Claude (model version not recorded), in a Claude Code session with the maintainer; shipped in on 2026-08-26. Not yet confirmed by a maintainer. These root classes were placed by reading them and their subclasses in the published graph, with the assistance of an AI agent. The reading, the evidence, and the refusals are recorded in reviewed_roots.yaml. See how categories are assigned.
