Contains MATR_nodes.tsv and MATR_edges.tsv. Releases are incremental, so this points at whichever release most recently rebuilt this ontology.

Per-edge-type (predicate) lists aren't recorded in the index for transformed ontologies — each edge carries predicate and relation columns in the KGX download. Total edges: 29.
