PURL WebIDs (was: WebID Frustration)

Greetings.

Replying to myself, here...

This doesn't _quite_ work (I thought I might as well try, rather than merely speculate), but I suspect it's not far off.

1. I chose an alternative WebID <http://purl.org/nxg/webid>.

2. I created a new certificate using Nicholas Humfrey's script at <https://gist.github.com/njh/2432427>, entering the above PURL, and a suitably distinct name "Norman Gray (purl webid)", I think.  I let it import the new certificate into my (OS X) keychain.

3. I copied the script's generated RDF/XML to a Dropbox file,...

4. ...and created a link to it

5. I went to purl.org and created the above WebID as a 'See other URL (303)', giving the Dropbox link as the SeeAlso url.

So: at this point, I have a WebID URL at purl.org which 303-redirects to a Dropbox URL which 302-redirects to another URL which returns RDF/XML which appears to me to conform to the WebID spec (I'm quietly impressed that this comes back down the wire with the correct application/rdf+xml content-type -- well done, Dropbox).

If, however, I now go to <https://webid.turnguard.com/WebIDTestServer/debug> and choose this associated certificate, I get a blank page.  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?

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! (and nearly works)

All the best,

Norman
