I need help writing a SPARQL query. If this isn't the right list to ask, suggestions would be appreciated.
-r I'm getting a reasonable result for the question "What Gems were written by some of the same authors?": PREFIX gi: <http://cfcl.com/RDF/SPARQLy/Gems/Gem#> PREFIX gs: <http://cfcl.com/RDF/SPARQLy/Gems/Spec#> SELECT DISTINCT ?gem WHERE { gi:12_hour_time-0.0.3 gs:authors ?authors . ?gem gs:authors ?authors . } ORDER BY ?gem ------------------------------------------------------------- | gem | ============================================================= | <http://cfcl.com/RDF/SPARQLy/Gems/Gem#12_hour_time-0.0.3> | | <http://cfcl.com/RDF/SPARQLy/Gems/Gem#12_hour_time-0.0.4> | ------------------------------------------------------------- However, I'd also like to ask the question "What Gems were written by _all_ of the same authors?".
