@afs I can provide more informations. ## 1. Design a rdf ontology with protege, generate a kg.owl file. > class: A B C， obejct properties: A :hasInclude B, A :hasApear C, B hasApear C. ## 2. generate a kg.ttl file with jena_d2rq-0.8.1 via mysql. > generate-mapping.bat -u xxx -p xxx -o kg.ttl jdbc:mysql://locahost:port/database_name?useSSL=false > mysql data structure: table A, Table B, Table C, Table A-B-map, Table A-C-map, Table B-C-map. ## 3.modify the kg.ttl to fit kg.owl > I don't think this step matters, beacuse another version without A :hasInclude B, do the same thing. ## 4. generate kg.nt file with jena_d2rq-0.8.1 via kg.ttl. > dump-rdf.bat -o kg.nt kg.ttl ## 5. generate tdb folder with apache-jena-4.4.0 > tdbloader.bat --loc=./tdb/ kg.nt ## 6. copy the kg.owl to fuseki's `run/databases/` path > cp kg.owl path_to/apache-jena-fuseki-4.4.0/run/databases/ontology.ttl ## 7. create a kg_cf.ttl file, and Fill the following configuration into the file > @prefix : <http://base/#> . @prefix tdb: <http://jena.hpl.hp.com/2008/tdb#> . @prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . @prefix ja: <http://jena.hpl.hp.com/2005/11/Assembler#> . @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> . @prefix fuseki: <http://jena.apache.org/fuseki#> . >:service1 a fuseki:Service ; fuseki:dataset <#dataset> ; fuseki:name "kg_demo" ; fuseki:serviceQuery "query" , "sparql" ; fuseki:serviceReadGraphStore "get" ; fuseki:serviceReadWriteGraphStore "data" ; fuseki:serviceUpdate "update" ; fuseki:serviceUpload "upload" . ><#dataset> rdf:type ja:RDFDataset ; ja:defaultGraph <#model_inf> ; . ><#model_inf> a ja:InfModel ; ja:baseModel <#tdbGraph> ; ja:content [ja:externalContent <../databases/ontology.ttl> ] ; > ja:reasoner [ja:reasonerURL <http://jena.hpl.hp.com/2003/OWLFBRuleReasoner>] . ><#tdbGraph> rdf:type tdb:GraphTDB ; tdb:dataset <#tdbDataset> ; . ><#tdbDataset> rdf:type tdb:DatasetTDB ; tdb:location "tdb" ; . ## 8. start fuseki server > fuseki-server.bat I do the same step, but only delete the obejct properties A :hasInclude B in ontology. this version will work will, count triples very fast. so I think maybe the cycle structure ontology make this issue. -- This is an automated message from the Apache Git Service.
