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 UBERON_nodes.tsv and UBERON_edges.tsv. Releases are incremental, so each link points at whichever release most recently rebuilt this ontology.
