Greetings, all


Relevant to the question of serving the FOAF file...

Circa. 2013 we have storage services such as Dropbox, Amazon S3, Google Drive, 
Microsoft SkyDrive, Box.NET etc.., all of these can host a profile document 
that describes claims that mirror those stored in your local keychain hosted 
X.509 cert. You simply use the SAN slot to connect these profile documents via 
a WebID and the leave the rest to logic expressible in queries delivered over 
HTTP e.g., SPARQL ASK  :-)

I just tried this.  My WebID <http://nxg.me.uk/norman/> does a 303 redirect to a FOAF 
file.  Right now, if you ask for text/turtle, it does a 303 redirect to 
<https://www.dropbox.com/s/getd5vxhafbutgl/norman.ttl>, which then does a 302 
redirect to some hash on Dropbox's content delivery network.

...and this still works, according to 
<https://webid.turnguard.com/WebIDTestServer/debug>!

This is, I suppose parenthetically, another way of doing the indirection that 
Hugh was talking about.  My WebID is merely a .htaccess file, but could be 
something like a purl.org URI redirecting to a file on Dropbox or similar.  
That's nice and easy.

(I don't think this would _quite_ work with purl.org right now, because of 
conneg intricacies, but it's near-as-dammit, and one can imagine a very similar 
service which did).

All the best,

Norman

Yep!
