is your entire graph contained in blank nodes hanging off a single subject? a pathological case that could be slow in any framework, (rebalancing, node-finding, isomorphism checks, yadda. see http://blog.datagraph.org/2010/03/rdf-isomorphism ) > I just want my triples printed out simplesy way is #yield parse_as_stream.(example http://gitorious.org/element/element/blobs/master/ruby/W/rdf.rb#line40 and theres gem using FFI rather than SWIG (possibly faster, possibly not) http://rdf.rubyforge.org/raptor/) to print pass triple-yield a function: eg resourcename.raptor{|s,p,o| puts"s "+s.class.to_s+" "+s.to_s+"\n"+ "p "+p.class.to_s+" "+p.to_s+"\n"+ "o "+o.class.to_s+" "+o.to_s} almost surely faster using a JSON model w/o SWIG sitting between: def fromStream m,*i send(*i) do |s,p,o| m[s] ||= {'uri'=>s} m[s][p] ||= [] m[s][p].push o end; m end model={} (E 'somefile.rdf').fromStream m, :redland ( i rarely use blank nodes, but when i do theyre just JSON objects in the literal position of a statement without a 'uri' field..) for just parsing, Raptor is extremely fast, perhaps the fastest... _______________________________________________ redland-dev mailing list [email protected] http://lists.librdf.org/mailman/listinfo/redland-dev
