Very well spotted Natanal . That was an error I introduced yesterday before the release. I have fixed it in the editor's draft


and we should make a quick fix release very soon. Thanks.

You can have an rdfs:seeAlso from your WebID Profile to something else. In fact on the WebId list we 
were just discussing what would be a good relation to point to a protected resource.

> But why should I remove the owl:Ontology? It is just a resource of rdf:type foaf:Person and owl:Ontology.

This is not really related to WebID, so I don't think it's an issue here, but people are not ontologies, so that you will later 
have trouble with that. But I don't want to get into a debate on that - if you can't see it then you'll experience it at a later point.

> The redirect is cause by our LinkedData extension for OntoWiki, because I thought its easier to manage a WebID with an OntoWiki compared to editing a text-file. Is there any other application which I can use to manage and server my WebID?

Well this makes for an interesting use case. Can you mail the WebID list the details of this setup in a new thread
on redirects. We are interested to see where redirects can be useful to justify possibly introducing this added complexity
into the spec. We are trying to keep things as simple as possible to get implementors on board. So we need to understand
why things like redirects could be useful, and also then look at the issues with security these may entail. I don't think
they do, but we then need to look at those issues.

For the moment it is certainly simpler to not use redirects. I think foafssl.org will accept them though.
