Hi, and thanks for your answers!
I got it to work now, but only for public workflows. For the non-rdf API, I
would use preemptive authentication like this to get a private workflow:
String urlString =
"http://www.myexperiment.org/workflows.xml?id=12345";;
HttpClient client = new HttpClient();
client.getParams().setAuthenticationPreemptive(true);
client.getState().setCredentials(
new AuthScope("www.myexperiment.org", 80),
new UsernamePasswordCredentials("user",
"password"));
GetMethod get = new GetMethod(urlString);
get.setDoAuthentication(true);
client.executeMethod(get);
I tried a similar thing for the rdf API, but it doesn't work. I get an empty
xml result if the workflow requires authentication. So, the uri from David:
http://rdf.myexperiment.org/sparql?query=PREFIX+mecontrib%3A+%3Chttp%3A%
2F%2Frdf.myexperiment.org%2Fontologies%2Fcontributions%2F%3E%0D%0APREFIX
+rdf%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F1999%2F02%2F22-rdf-syntax-ns%23%3E%

273bd356a4-fc82-4ec8-8fcb-5960f40b2e8f%27%29%0D%0A%7D
works fine, but if I replace the id with one of my own, then it doesn't find
the workflow.
So the question is: Can I use the rdf API to retrieve an id of a private
workflow?

Dennis
