Neo4j 4.0.1 fails to import ontologies

[StrangeTcy]

On Ubuntu 18.04 with neo4j 4.0.1 and neosemantics 3.5.0.4 (latest release at the time of this writing) I try to reproduce the results from quickgraph #9, but running the

CALL semantics.importOntology( "http://www.nsmntx.org/2019/10/clothingMaterials", "Turtle", { keepLangTag: true, handleMultival: 'ARRAY'})

query results in an error:

Failed to invoke procedure semantics.importOntology: Caused by: java.lang.NoSuchMethodError: 'org.neo4j.graphdb.schema.Schema org.neo4j.graphdb.GraphDatabaseService.schema()'

At the same time, a simple call semantics.importOntology() gets an expected error about no arguments being provided. ETA: it's the same for semantics.importRDF() and, so, quickgraph #10

My guess is that neosemantics 3.5 can't find some method in neo4j 4.0 due to some renaming, but probably that's not the cause of this.

Yes, the 3.5.x releases of neosemantics were not compatible with Neo4j 4.0. Hopefully you'll be able to make it work with the 4.0.x release. The syntax will change a bit, as described in the migration guide, but it should be pretty straightforward: CALL n10s.graphconfig.init({ keepLangTag: true, handleMultival: 'ARRAY'}); CALL n10s.onto.import.fetch("http://www.nsmntx.org/2019/10/clothingMaterials", "Turtle");

Please comment if you find any issue.

Cheers,
