Visibility: Public

A KGX transformation of the BioPortal ontology Ontology for MicroRNA Target (OMIT), 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 OMIT_nodes.tsv and OMIT_edges.tsv. The full graph contains OMIT_full_nodes.tsv and OMIT_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 · 1 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.

An item carrying more than one category is counted under each, so these counts can add up to more than the total.

How they were assigned 87,815 of 87,857 nodes (100.0%)

27,934inherits from a seed term above it in the hierarchy
59,875inherits from a root class placed by review

59,875 of these nodes inherit a category from 1 root class 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.
