yes. Good - I logged in with my WebID at https://pilot5.poolparty.biz:8443/PoolParty/index.jsp

So now the next thing is just to put the name you find in my profile there. The fact that a lot of implementations for such a long time put the WebID there (eg. foaf.me ) is I think part of the reason that we end up being so unconvincing, and why we then have to fight so much with weird arguments about e-mail addresses being so much better identifiers than http urls. It is really important to show just how powerful access to the WebID profile is.

The URL should be a last fallback. If you need to use the CN in the DN in the certificate, that would be a better fallback even.
You could also hyperlink the name to the foaf file, or something of that sort.

And what if the code on your test server is slightly out of step with the other one? Then you'll have weird cases where people can log into one but not to there other and it will be very difficult to debug.

Well that's not surprising :-) It's an http URL.
Did you mean to say https://pilot5.poolparty.biz:8443/PoolParty/index.html is the one that is viewable without a
certificate?

I thought the cool think about your tomcat wrapper, as you explained today was that you could specify some URLs on the
https endpoint which would not require the client to show his certificate.

True, our queries are very simple! But then you should probably search for cert:key too. cert:identity is deprecated now.

My mistake. I thought you were using Jena, when in fact you were using Sesame....

That sounds very good. Making it possible to fetch groups and ACLs remotely opens up a lot of possibilities. For example I just added Domel to the WebID team, and I don't really want to feel like I am giving you work every time I add someone :-)

That's great for me.

Thanks for the very interesting work.
