Hi everyone,I tried fetching some RSS feeds and getting triples for it: - The user has SPARQL_SPONGE permissions - The cartridges are enabled, I see one for feeds and the options seem to make sense in the configuration (didn't change the defaults) - I told it to download all data it needs (tried all options in there) - Query looks like "select * from<URL-of-a-txt-file> where { ?s ?p ?o }" according to the docs in the wiki, I tried: "select * from<http://feeds.feedburner.com/Precentralnet?format=xml> where { ?s ?p ?o }" but I get no triples back. Do I miss something there?
Yes, do: define get:soft "replace" select * from <http://feeds.feedburner.com/Precentralnet?format=xml> where { ?s ?p ?o } The first line is a pragma that tells the SPARQL engine to do the following: 1. HTTP GET using IRI in FROM clause as a URL 2. If a Graph IRI already exists based on URL then overwrite (i.e. replace). Kingsley
