 # Human Brain Atlas Ontology
 
 This repository contains an application ontology built by combining ontologised versions of the Allen Institute Human Brain Atlas (HBA) StructureGraph mapped to Uberon. 
 
-More information can be found at https://brain-bican.github.io/human_brain_atlas_ontology/
+The Allen Structuregraph JSON from which this is built can be found at: https://api.brain-map.org/api/v2/structure_graph_download/10.json
+
+This structuregraph represents that browseable graph of annotations present in the Allen "[Human Brain Guide](https://atlas.brain-map.org/atlas?atlas=265297125)" atlas.
+
+Mappings to Uberon are hosted on the Uberon repo: [uberon-bridge-to-aba.owl](https://raw.githubusercontent.com/obophenotype/uberon/master/src/ontology/bridge/uberon-bridge-to-aba.owl).
