I recently downloaded a ZIP file in RDF format from the Barcelona Open Data web page.
This format is a subset (or that is what I understand) of XML. I’ve been trying to parse it with an objective C API (NSXMLParser), but all my efforts have brought no happy ending. I have searched Stack Overflow for hours and nobody appears to have any info into how to work with this type of data.
Anybody here has any experience working with RDF formats? Any tips or guidelines?
