Metagenome Sample Vocabulary

KGXBioPortal ontologyv0.2
Visibility: Public

A KGX transformation of the BioPortal ontology Metagenome Sample Vocabulary (MSV), 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 MSV_nodes.tsv and MSV_edges.tsv. Releases are incremental, so each link points at whichever release most recently rebuilt this ontology.

Imports 2 · 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.

Biolink categories 2 categories across 1,557 nodes

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 1 of 1,557 nodes (0.1%)

1inherits from a root class placed by review

1 of these nodes inherits 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.
