Base graph is the full graph

This ontology declares no imports, so its base graph already is its full graph; nothing separate was built.

The graph contains BT_nodes.tsv and BT_edges.tsv. Releases are incremental, so each link points at whichever release most recently rebuilt this ontology.

Biolink categories 2 categories across 576 nodes

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