I am new to Apache Solr. I want to import an rdf file into solr for indexing. I have googled, but I did not find anything useful. please give me some pointers.
Solr accepts JSON documents. You can convert your RDF document to a JSON-LD document. JSON-LD is an RDF serialization format and is part of RDF 1.1. You can safely navigate between JSON-LD and other RDF serializations and not lose any data.
Take a look at the HttpDataSource DataImportHandler Example . He talks about RDF processing using XPathEntityProcessor.
Edit - Another Blog - RDF Aggregates and Full-Text Steroid Search with Solr
You can also look for Siren that can add RDF data in lucene
My 2 cents on this experiment, let me know what you think: http://andreagazzarini.blogspot.it/2014/12/a-solr-rdf-store-and-sparql-endpoint-in.html
