I suppose it's possible that webid.turnguard.com is presuming Turtle or RDFa, but ...ooh, Jürgen Jakobitsch is in this thread -- any ideas, Jürgen? > > ---- hi, norman. webIDRealm's dereference method accepts any format it has a parser for (inclusive of rdfa, for which i modified openrdf's version to work on a local catalog to keep w3c servers' peace) thing is that in the end of all redirections the httpconnection determines the content type of the response to be text/html for which there's no parser of course. here's the code of the dereference method : http://sourceforge.net/p/webidrealm/code/17/tree/trunk/src/main/java/com/turnguard/webid/utils/WebIDUtils.java#l159 you can see the exception if you use http://webid.turnguard.com/WebIDTestServer/utils/parser paste your webID and hit Parse URI, it will use HttpUtils.dereference in WebIDUtils.java (see above). i'll still need to figure why text/html is the determined contentType.. i'll let you know. wkr jürgen > > Interestingly, none of steps 1, 2 and 3 involved the web (once I'd downloaded the script, that is), and specifically they did not involve a certificate-generating service); step 4 involved a service (Dropbox) I'm already familiar with; as did step 5, though admittedly that's a more exotic interest than Dropbox. > > Steps 1, 2 and 3 did involve a gist, running a shell-script, and cut-and-pasting a block of text into a file, but making that nicer is just a matter of UI design and the right scripting language. > > Hey -- this stuff is easy!
