Hi, I am trying to import an ontology:
Here's what I'm doing:
CALL n10s.graphconfig.init();
I read that it might be related to memory allocation of neo4j. To test that, I tried an even bigger ontology and it was loaded successfully. However this ontology (link attached), is throwing exception (also attached).
CALL n10s.onto.import.fetch("<path_to_file>","RDF/XML",{commitSize: 100000, nodeCacheSize: 20000})
This is the error I'm getting:
2023-02-01 13:42:27.670+0000 ERROR [o.n.k.a.p.GlobalProcedures] Problems when running partial commit. Partial transaction rolled back. 53203 triples lost.
