Hi, it seems you missed to initialize TDB for ex.
[] ja:loadClass "com.hp.hpl.jena.tdb.TDB" . tdb:DatasetTDB rdfs:subClassOf ja:RDFDataset . tdb:GraphTDB rdfs:subClassOf ja:Model . Regards, Sorin Am 25.05.2022 um 08:03 schrieb [email protected]:
I have a TDB2 database with a dataset named "test". Via fuseki UI I can run SparQL queries without any problems. Now I want to index my dataset with the following command: java -cp ./fuseki-server.jar jena.textindexer --desc=run/assembler.ttl I get this error: the root https://km-ps.com/model/data/myDataset has no most specific type that is a subclass of ja:Object doing: root: https://km-ps.com/model/data/mytextDataset with type: http://jena.apache.org/text#TextDataset assembler class: class org.apache.jena.query.text.assembler.TextDatasetAssembler This is my assembler.ttl: @prefix : <https://km-ps.com/model/data/> . @prefix owl: <http://www.w3.org/2002/07/owl#> . @prefix kgdomain:<https://km-ps.com/model/domain#> . @prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> . @prefix tdb: <http://jena.hpl.hp.com/2016/tdb#> . @prefix text: <http://jena.apache.org/text#> . @prefix skos: <http://www.w3.org/2004/02/skos/core#> @prefix fuseki: <http://jena.apache.org/fuseki#> .
