I am following the quite excellent tutorial on loading OpenPermId data (
https://jbarrasa.com/2018/02/01/neo4j-is-your-rdf-store-part-3-thomson-reuters-openpermid/) and discovered that the tr-vcard namespace that is reference on line
51389 of the file
OpenPermID-bulk-person-20180916_070349.ttl
is not defined in the file itself. I added
@prefix tr-vcard: <http://permid.org/ontology/tr-vcard/>; .
to the top of the .ttl file, and now it loads. The error I was getting was:
Namespace prefix 'tr-vcard' used but not defined [line 51389]
