Re: Marketing troubles - workable WebID profile generators

one more remark for info :

there is an encoding issue with (at least) german umlauts @ http://webid.fcns.eu/
when i curl my foaf-uri, accepting rdf+xml everything is fine, but in the certificate
the umlauts are messed up.

hi henry, thanks for your answer and work in generell.

we will communicate this page [1] for creating
foaf-uris and webids now.

i just tested it and it works. only remark :

it also creates the cert#hex as a predicate and not as a datatype.
i have already implemented a (still to be improved) workaround in webIDRealm for that special case
which should now work with foaf.me and fcns.eu generated foaf-profiles

Yes, I think that is probably very much in its last stages. It never really evolved beyond what it was 4 years ago as far as I can tell. A major problem is that it allows people to edit the xml, which of course is a no go as far as ease of use goes.

Yes, you are quite right. That produces WebID profiles that use the deprecated ontology.
I put that together 1 and a half years ago quickly. I could try to update it, but I am not sure I will have time
in the near future (even if it should not take a lot of time, it's perhaps a few hours for me to remember how that whole system works, and things may have evolved a lot in the xwiki platform) I'd rather work on a better version using my branch of http://clerezza.org/ on http://github.com/bblfish/clerezza.

The best work recently put together was the server at http://webid.fcns.eu/ by Andrei Sambra.

That has a nice user interface, has a test suite and works.

Things can still be improved a lot in my view as far as user interfaces go. We are only at the very beginning here. And because the benefits of WebID pivots around ease of use, I must say that we still don't have demos that do it full justice.

This is the new accepted way to do it, and this is how the examples should be written out in the spec.

It is worth supporting this way too, for backward compatibility. You can see the code that I use
in Scala here:

https://github.com/bblfish/clerezza/blob/bblfish/parent/platform.security.foafssl/core/src/main/scala/org/apache/clerezza/foafssl/auth/WebIDClaim.scala

or in Java using SPARQL, which I think ends up being easier to read:

https://github.com/bblfish/foafssl-java/blob/master/foafssl-verifier-sesame/src/main/java/net/java/dev/sommer/foafssl/sesame/verifier/SesameFoafSslVerifier.java

thanks a lot.

What would be great is if you could give people who have profiles on your system a WebId too. We just need more WebID generators and more competition and presentation ideas.
