Hello all, I am trying to load an RDF graph to Jena Fuseki (the latest release). The load process is completed without any warn or error, however, when I try to query the loaded RDF, some triples are missed. Here are the test RDF graph, the SPARQL query, and the result. I can't understand what is going on. Any help?
RDF graph: <?xml version="1.0"?> <rdf:RDF xmlns:vocab="http://localhost:2020/vocab/" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:map="http://localhost:2020/#" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:bibo="http://purl.org/ontology/bibo/" xmlns:foaf="http://xmlns.com/foaf/0.1/" xmlns:db="http://localhost:2020/" xmlns:owl="http://www.w3.org/2002/07/owl#" xmlns:dcterms="http://purl.org/dc/terms/" xmlns:xsd="http://www.w3.org/2001/XMLSchema#" xmlns:fabio="http://purl.org/spar/fabio/" xmlns:dbpedia-owl="http://dbpedia.org/ontology/" xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#" xmlns:swrc="http://swrc.ontoware.org/ontology#" xml:base="http://localhost:2020/" > <rdf:Description rdf:about="article/1532"> <swrc:journal rdf:resource="journal/4"/> <fabio:hasPublicationYear rdf:datatype="http://www.w3.org/2001/XMLSchema#integer">2008</fabio:hasPublicationYear> <bibo:uri>http://www.medisur.sld.cu/index.php/medisur/article/view/353</bibo:uri> <fabio:abstract>Some text here.</fabio:abstract> <dc:source>Medisur; Vol 6, No 1 (2008); 22-27</dc:source> <dc:title>Efectividad del misoprostol para el aborto en el primer trimestre del embarazo en adolescentes.</dc:title> <dc:identifier>oai:ojs.localhost:article/353</dc:identifier> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#date">2008-04-02</dc:date> <rdfs:label>Efectividad del misoprostol para el aborto en el primer trimestre del embarazo en adolescentes.</rdfs:label> <rdf:type rdf:resource="http://purl.org/spar/fabio/JournalArticle"/> <dc:creator rdf:resource="author/3037"/> <dc:creator rdf:resource="author/3038"/> <dc:creator rdf:resource="author/3039"/> <dc:creator rdf:resource="author/3040"/> <dc:creator rdf:resource="author/3041"/> <dc:creator rdf:resource="author/3042"/> <fabio:InCollection rdf:resource="set/36"/> </rdf:Description> <rdf:Description rdf:about="author/3037"> <foaf:name>Práxedes Rojas Quintana</foaf:name> <rdfs:label>Práxedes Rojas Quintana</rdfs:label> <rdf:type rdf:resource="http://xmlns.com/foaf/0.1/Person"/> </rdf:Description> <rdf:Description rdf:about="author/3038"> <foaf:name>Pedro Ayo Naranjo</foaf:name> <rdfs:label>Pedro Ayo Naranjo</rdfs:label> <rdf:type rdf:resource="http://xmlns.com/foaf/0.1/Person"/> </rdf:Description> <rdf:Description rdf:about="author/3039"> <foaf:name>Alberto Jorge Fernández</foaf:name> <rdfs:label>Alberto Jorge Fernández</rdfs:label> <rdf:type rdf:resource="http://xmlns.com/foaf/0.1/Person"/> </rdf:Description> <rdf:Description rdf:about="author/3040"> <foaf:name>Israel Sotolongo Castro</foaf:name> <rdfs:label>Israel Sotolongo Castro</rdfs:label> <rdf:type rdf:resource="http://xmlns.com/foaf/0.1/Person"/> </rdf:Description> <rdf:Description rdf:about="author/3041"> <foaf:name>Joan Hernández Cabrera</foaf:name> <rdfs:label>Joan Hernández Cabrera</rdfs:label> <rdf:type rdf:resource="http://xmlns.com/foaf/0.1/Person"/> </rdf:Description> <rdf:Description rdf:about="author/3042"> <swrc:affiliation>Hospital provincial universitario “Dr. Gustavo Aldereguía Lima”.

It is normal this behavior? Best regards. Yusniel Hidalgo. 1519-2019: Aniversario 500 de la Villa de San Cristóbal de La Habana Por La Habana, lo más grande. #Habana500 #UCIxHabana500
