Hi everyone! We'd like to propose a simple extension to RDB2RDF called rrx:languageColumn to specify the language of a literal dynamically. @prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>. @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>. @prefix owl: <http://www.w3.org/2002/07/owl#>. @prefix rr: <http://www.w3.org/ns/r2rml#>. @prefix rrx: <http://purl.org/r2rml-ext/>. rrx:languageColumn a owl:DatatypeProperty; rdfs:domain rr:TermMap; rdfs:range rdf:Literal; rdfs:comment "Specifies the language of a literal, to be retrieved from a column (whereas rr:language is a constant string)". This can be used in R2RML scripts like so: rr:predicateObjectMap [ rr:predicate dc:title; rr:objectMap [ rr:column "TITLE"; rrx:languageColumn "TITLE_LANG"; ]. We've implemented it as a patch to the perl module RDF::RDB2RDF, and I've spoken to Juan whether it'd be possible to add it to Ultrawrap. Your feedback on whether there's a better way will be appreciated.
