A framework that combines data from the UMLS with assertions from other data sources into a set of CSV files that can be imported into neo4j to build a Unified Biomedical Knowledge Graph (UBKG)
DOID, on the other hand, uses ordo as the SAB in the dbxref column. The result is that if a DOID node only has a cross-reference to a node in Orphanet, the cross-reference will not be set in UBKG.
Solution
Either map the Orphanet IRIs to the SAB ORDO or map ORDO to Oprhanet.
Statement of problem
When ingesting Orphanet, the current generation framework maps Orphanet IRIs (e.g., http://www.orpha.net/ORDO/Orphanet_69028) to nodes with SAB of ORPHANET.
