c# - DotNetRDF & AllegroGraph -


i'm working on application bulk parsing , uploading allegrograph triplestore, have run snag. able open , read graph in question using below code:

        allegrographconnector conn = new allegrographconnector(myhost, mygraph, myusername, mypassword);          graph g = new graph();         conn.loadgraph(g, "");          g.baseuri = new uri(mog);         foreach (rtsnode r in _nodes)         {             iurinode sbj = g.createurinode(new uri(rtsuri + r.myname));             iurinode pred = g.createurinode(new uri(mog));             iliteralnode obj = g.createliteralnode(r.myname, "en");              g.assert(new triple(sbj, pred, obj));         }          conn.savegraph(g);

as mentioned graph loads fine , triples being added local version. when attempt save it, 400- bad request error. turning on full debugging shows error due to:

unsupported file format: 'application/n-triples' not supported content-type

is there option changing default format allegrographconnector communicates?

thank time.

what version of dotnetrdf using?

this sounds bug fixed in our recent 1.0.8 release first try upgrading latest version should resolve issue

update

so looks bug in allegrograph, according documentation expecting mime type ntriples text/plain whereas current systems (including dotnetrdf) use standard application/n-triples mime type ntriples.

currently there no workaround this, filed core-447 fixed next release

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver.
