Hi, I'm using Jena's ARQ to parse a large amount of URI encoded queries. I would like to ask if someone would have a tip for the best way to preprocess queries before feeding them to ARQ.
Problem is that if I use simple URI decoding everything gets decoded. For example, if I have encoded query: %0APREFIX%20foaf%3A%20%3Chttp%3A%2F%2Fxmlns.com%2Ffoaf%2F0.1%2F%3E%0APREFIX%20p%3A%20%20%3Chttp%3A%2F%2Fdbpedia.org%2Fproperty%2F%3E%0ASELECT%20%2A%20WHERE%20%7B%20%0A%20%20%20%20%20%20%3Chttp%3A%2F%2Fdbpedia.org%2Fresource%2FThomas_%22Scotch_Tom%22_Nelson%3E%20p%3Aabstract%20%3Fabstract.%0A%20%20%20%20%20%20%3Chttp%3A%2F%2Fdbpedia.org%2Fresource%2FThomas_%22Scotch_Tom%22_Nelson%3E%20foaf%3Apage%20%3Fwiki.%20%0A%20%20%20%20%20%20OPTIONAL%20%7B%3Chttp%3A%2F%2Fdbpedia.org%2Fresource%2FThomas_%22Scotch_Tom%22_Nelson%3E%20foaf%3Adepiction%20%3Fimg.%7D%0A%20%20%20%20%20%20FILTER%20%28lang%28%3Fabstract%29%20%3D%20%27en%27%29%0A%20%20%20%7D%0A it turns into \nPREFIX foaf: <http://xmlns.com/foaf/0.1/>\nPREFIX p: <http://dbpedia.org/property/>\nSELECT * WHERE { \n <http://dbpedia.org/resource/Thomas_"Scotch_Tom"_Nelson> p:abstract ?abstract.\n <http://dbpedia.org/resource/Thomas_"Scotch_Tom"_Nelson> foaf:page ?wiki. \n OPTIONAL {<http://dbpedia.org/resource/Thomas_"Scotch_Tom"_Nelson> foaf:depiction ?img.}\n FILTER (lang(?abstract) = 'en')\n }\n" which cannot be parsed because of quotes in http://dbpedia.org/resource/Thomas_"Scotch_Tom"_Nelson. Is there some canonical way how to do the preprocessing correctly ? Thank you very much. Svatopluk Šperka
