Thanks for the answers, i guess i will save it. The reason i'm using a xml parser is that the libraries for rdf are huge in java, 30mb like, in contrast with stax or sax that is in jdk. Also i'm doing a client program, even if the only client is me ;)

Paulo, maybe this will help. I've taken the catalogue and put it in the laboratory triple store (http://river.styx.org/sparql) for you. You can try a query like, PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> PREFIX dc: <http://purl.org/dc/elements/1.1/> PREFIX dcterms: <http://purl.org/dc/terms/> PREFIX gut: <http://www.gutenberg.org/feeds/catalog.rdf#> SELECT DISTINCT ?download, ?mimetype FROM <http://www.gutenberg.org/feeds/catalog.rdf> WHERE { ?download dcterms:isFormatOf gut:etext12345 . ?download dc:format ?format . ?format rdf:value ?mimetype } and get output in any number of formats like JSON and such. Canned version of this query: http://bit.ly/cUIPqm Let me know if this is helpful to you. Cheers, -w
