The sparql command I use is:
String query=
"PREFIX dcterms: <http://purl.org/dc/terms/> "+
"PREFIX mebase:
<http://rdf.myexperiment.org/ontologies/base/> "+
"PREFIX snarm:
<http://rdf.myexperiment.org/ontologies/snarm/> " +
"PREFIX sioc: <http://rdfs.org/sioc/ns#> " +
"PREFIX mevd:
<http://rdf.myexperiment.org/ontologies/viewings_downloads/> "+
"select distinct ?url ?title ?description ?author ?viewed
?downloaded " +
"where "+
"{ "+
" ?workflow dcterms:type ?thetype . "+
" ?workflow dcterms:title ?title . "+
" ?workflow dcterms:description ?description . "+
" ?workflow mebase:has-policy ?policy ."+
" ?workflow mebase:content-url ?url . " +
" ?workflow sioc:has_owner ?author . " +
" ?workflow mevd:viewed ?viewed . " +
" ?workflow mevd:downloaded ?downloaded . " +
" ?policy snarm:has-access
<http://rdf.myexperiment.org/ontologies/specific/PublicDownload> ." +
" FILTER
(REGEX(?thetype,'application/vnd.taverna.scufl\\\\\\+xml')) "+
"} ";
for T1 workflows
String query=
"PREFIX dcterms: <http://purl.org/dc/terms/>"+
"PREFIX mebase:
<http://rdf.myexperiment.org/ontologies/base/> "+
"PREFIX snarm:
<http://rdf.myexperiment.org/ontologies/snarm/> " +
"PREFIX sioc: <http://rdfs.org/sioc/ns#> " +
"PREFIX mevd:

"select distinct ?url ?title ?description ?author ?viewed

" ?policy snarm:has-access
<http://rdf.myexperiment.org/ontologies/specific/PublicDownload> ." +
" FILTER (REGEX(?thetype,'taverna2beta')) "+
"} ";
For T2 workflows.
To make it automatic I prepare a POST query and send it to
http://rdf.myexperiment.org/sparql and I get XML file with links to all
the workflows
