Thaer Whoa, hold everything! You said RDF, meaning resource description framework? If so, you have exactly three fields: subject, predicate, and object. Maybe they are text type, or for exact matches you might want string fields. Add an ID field, which could be automatically generated by Solr, so now you have four fields. Or am I on a tangent again?
