I have a RDF graph stored in Fuseki. This graph has resources describing metadata fields from research articles such as title, authors, abstract, etc. Also, I have the corresponding PDF file for each resource in RDF graph. So, I need to build a query over the RDF graph and retrieve their corresponding PDF file or viceversa. Is there any way to do that?
PD: The RDF graph is stored in Fuseki, and the PDF files are indexed in Apache Solr.
Thank you very much. SPARQL is just for querying RDF graphs, however, we don't find a way to querying the Solr index in the same SPARQL query. Recently, I found the Jena text-query module. Best regards.
I suggest to use Ontotext that could be helpful in your case. Ontotext provides a complete set of semantic technologies enabling better content management, knowledge discovery and semantic search.
