-<tref>public key</tref>s using the <code>cert</code> and <code>rsa</code>

-<p>The document can publish many more relations than are of interest to the
-WebID protocol, as shown in the above graph by the grayed out relations.</p>
-<p>The encoding of this graph is immaterial to the protocol, so long as a well
-known mapping to the format of the representation to such a graph can be found.
-Below we discuss the most well known formats, and a method for dealing with new
-unknown formats as they come along.</p>
-<p>The WebID provider must publish the graph of relations in one of the well
-known formats, though he may publish it in a number of formats to increase the
-usability of his site using content negotiations.</p>
-<p class="issue">Add content negotiation pointers</p>
+<p>The <tref>WebID Profile</tref> document MUST expose the relation between the <tref>WebID URI</tref> and the <tref>Identification Agent</tref>'s <tref>public key</tref>s using the <code>cert</code> ontologies, as well as the standard <code>xsd</code> datatypes.
+The set of relations to be published at the <tref>WebID Profile</tref> document can be presented in a graphical notation as follows.</p>
+
+<img alt="Web ID graph" width="90%" src="img/WebIdGraph.jpg"/>
+<p>The document can publish many more relations than are of interest to the WebID protocol, as shown in the above graph by the grayed out relations. 
+For example Bob can publish a depiction or logo, so that sites he authenticates to can personalise the user experience. He can post links to people he knows, where those are have WebIDs published on other sites, in order to create a distributed Social Web. 
+He can also publish relations to protected documents, where he keeps more information for people who authenticate, such as his friend Alois or his friends friends who may not yet know him personally, such as Alice.</p>
+<p>
+The protocol does not depend on any particular serialisation of the graph, provided that agents are able to parse that serialisation and obtain the graph automatically.  
+Technologies such as GRDDL [[!GRDDL-PRIMER]] for example permit any XML format to be transformed automatically to a graph of relations.
+Yet for reasons of interoperabity is has been decided that the document MUST be published at least in one of RDFa [XHTML-RDFA] or RDF/XML [RDF-SYNTAX-GRAMMAR]. 
+HTTP Content Negotiation [SWBP-VOCAB-PUB] can be employed to aid in publication and discovery of multiple distinct serialisations of the same graph at the same URL. </p>
+<p>
+Irrespective of whether content negotiation can or not be employed, if an HTML representation of the WebID profile is published, it is suggested that the provider uses the HTML or XHTML <code>link</code> element to allow discovery of the various alternate representations of the graph which may be available:
+</p>
+
+<pre class="example">
+...
+&lt;html xmlns="http://www.w3.org/1999/xhtml"&gt;
+&lt;head&gt;
+&lt;title&gt;&lt;/title&gt;
+&lt;link rel="alternate" type="application/rdf+xml" href="profile.rdf"/&gt;
+&lt;link rel="alternate" type="text/turtle" href="profile.ttl"/&gt;
+&lt;/head&gt;
+...
+</pre>
 <p>It is particularly useful to have one of the representations be in HTML or
 XHTML even if it is not marked up in RDFa as this allows people using a
 web browser to understand what the information at that URI represents.</p>
 <section class='normative'>
 <h1>Turtle</h1>

 <h1>Authentication Sequence</h1>
 
-<img src="img/WebIDSequence-friendly.jpg">
-<p>The following steps are executed by <tref>Verification Agent</tref>s and
-<tref>Identification Agent</tref>s to determine the global identity of the
-requesting agent. Once this is known, the identity can be used to determine
-if access should be granted to the requested resource.
+<p>In order to give the full context of a <tref>Client</tref> interaction with a <tref>Server</tref> we will illustrate the protocol with the following sequence diagram. <tref>Bob</tref> initiates a connection to <tref>Alice</tref>'s server via a TLS enabled protocol such as https in order to access a Protected Resource or a Protected Service. The Protected Resource may be a document served over https, but it could also be a SOAP service, or some other resource. This resource is protected by a Guard, which uses a <tref>WebID Verifier</tref> to verify the non Certified WebIds found in the certificate. Once the verification succeeds the Guard checks to see if the Agent identified by the <tref>WebID</tref> is allowed access to the resource, by using trusted information from the Web and access control rules. 
+
 </p>
 
+<img width="90%" src="img/WebIDSequence-friendly.jpg">
+<p>The steps in detail are as follows:</p>
+<ol>
+<li><tref>Bob</tref>'s <tref>Client</tref> MUST open a TLS [[!RFC5246]] connection with the server which authenticates itself using well known TLS mechanisms. This MAY be done as the first part of an HTTPS connection [[!HTTP-TLS]].</li>
+<li>Once the Transport Layer Security [TLS] has been set up, the application protocol exchange can start. If the protocol is HTTP then the client can request an HTTP GET, PUT, POST, DELETE, ... action on a resource as detailed by [[!HTTP11]]. The <tref>Guard</tref> can then intercept that request and by checking some access control rules determine if the client needs authentication. We will consider the case here where the client does need to be authenticated.</li>
+
+<li>The Guard MUST requests the client to authenticate itself using public key cryptography by signing a token with its private key and have the Client send its Certificate. This has been carefully defined in the TLS protocol and can be summarised by the following steps:
+<ol>
+<li>The guard requests of the TLS agent that it make a Certificate Request to the client. The TLS layer does this. Because the WebID protocol does not rely on Certificate Authorities to verify the contents of the <tref>Certificate</tref>, the TLS Agent can ask for any Certificate from the Client. More details in <a href="requesting-the-client-certificate">Requesting the Client Certificate</a></li>
+<li>The Client asks Bob to choose a certificate if the choice has not been automated. We will assume that Bob does choose a <tref>WebID Certificate</tref> and sends it to the client.</li>
+<li>The <tref>TLS Agent</tref> MUST verify that the client is indeed in posession of the private key. What is important here is that the TLS Agent need not know the Issuer of the Certificate, or need not have any trust relation with the Issuer. Indeed if the TLS Layer could verify the signature of the Issuer and trusted the statements it signed, then step 4 and 5 would not be needed - other than perhaps as a way to verify that the key was still valid.</li>
+
+<li>The <tref>WebID Certificate</tref> is then passed on to the <tref>Guard</tref> with the proviso that the WebIDs still needs to be verified.</li>
+</ol>
+</li>
+<li>The <tref>Guard</tref> then MUST ask the <tref>Verfication Agent</tref> to verify that the WebIDs do identify the agent who knows the given public key.</li>
+
+<li>The WebID is verified by looking up the definition of the URL at its canonical location. This can be done by dereferencing it. The <tref>Verification Agent</tref> MUST extract the <tref>public key</tref> and all the URI entries contained in the <code>Subject Alternative Name</code> extension of the <tref>WebID Certificate</tref>.  A <tref>WebID Certificate</tref> MAY contain multiple URI entries
+which are considered claimed <tref>WebID</tref>s at this point, since they have not been verified. The <tref>Verification Agent</tref> may verify as many or as few WebIDs it has time for. It may do it in parallel and asynchronously. However that is done, a claimed WebIDs can only be considered verified if the following steps have been accomplished successfully:</li>
+
 <ol>
-<li>The <tref>Identification Agent</tref> (Bob's Browser) requests an action (GET, PUT, POST, DELETE, ... ) on a resource managed by the <tref>Verification Agent</tref> (Alice's Web Server) using HTTP over a TLS connection [[!HTTP-TLS]] . </li>
-
-<li>The <tref>Verification Agent</tref> decides if it needs to authenticate the user, by potentially taking into consideration the Method of the request, the resource and the capabilities of the browser as well as acces control permissions for that resource. Some servers may require all requests to be identified, others may only require some resources to be accessed by identified agents. If the server requires the <tref>Identification Agent</tref> to be identified, then it can ask for the agent's cleint certificate using the null DN [to be discussed: do we have a DN for WebID enabled TLS ] in a  TLS client-certificate Request message. </li> 
+<li>If the <tref>WebID Verifier</tref> does not have an up to date version of the WebID profile in the cache, then it MUST dereference the WebID using the canonical method for dereferencing a URL of that scheme. For an https://... WebID this would be done using the [[!HTTP-TLS]] protocol. </li>
+<li>The returned representation is then transformed into an RDF graph as specified in <a href="#processing-the-webid-profile">Processing the WebID Profile</a> </li>
+<li>That graph is then queried as explained in <a href="#querying-the-graph">Querying the Graph</a>. If the query succeeds, then that WebID is verified.
 </li>
-

 <h2>Initiating a TLS Connection</h2>
 
-<p class="issue">This section will detail how the TLS connection process is
-started and used by WebID to create a secure channel between the
-Identification Agent and the Verification Agent.</p>
+<p>Standard SSLv3 and TLSv1 and upwards can be used to establish the connection between
+the Client and the TLS Agent listening on the Service's port. </p>
+<p class="note">Many servers allow a simple form of TLS client side authentication to be setup when configuring a <tref>TLS Agent</tref>: they permit the agent to be authenticated in WANT or NEED mode.
+If the client sends a certificate, then neither of these have an impact on the <tref>WebID Verification</tref> steps (4) and (5).
+Nevertheless, from a user interaction perspective both of these are problematic as they either force (NEED) or ask the user to authenticate himself even if the resource he wishes to interact with is public and requires no authentication. 
+People don't usually feel comfortable authenticating to a web site on the basis of a certificate alone. 
+They prefer human readable text, and detailed error messages which the HTTP layer deliver.
+
+It is better to move the authentication to the application layer <tref>Guard</tref> as it has a lot more information about the application state. 
+Please see the <a href="http://www.w3.org/2005/Incubator/webid/wiki/">WebID Wiki</a> for implementation pointers in different programming languages and platforms to learn about how this can be done and to share your experience.</p>

-<p class="issue">This section will detail how the certificate is selected and
-sent to the Verification Agent.</p>
+<p>Once the TLS connection has been setup, the application layer protocol interaction can start.
+This could be an HTTP GET request on the protected resource for example.
+<p>If the protocol permits it, the Client can let the Application layer, and especially the <tref>Guard</tref> know that the client can authenticate with a WebID Certificate, and even if it wishes to do so. This may be useful both to allow the Server to know that it can request the client certificate, and also in order to make life easier for Robots that may find it a lot more convenient to be authenticated at the TLS layer.

+<h2>Requesting the Client Certificate</h2>
+
+<p>TLS allows the server to request a Certificate from the Client using the <code>CertificateRequest</code> message [section 7.4.4] of TLS v1.1 [[!RFC5246]].  Since WebID TLS authentication does not rely on CA's signing the certificate to verify the WebID Claims made therein, the Server does not need to restrict the certificate it receives by the CA's they were signed by. It can therefore leave the  <code>certificate_authorities</code> field blank in the request. </p>
+<p class="note">From our experience leaving the certificate_authorities field empty leads to the correct behavior on all browsers and all TLS versions.</p>
+<p class="note">A security issue with TLS renegotiation was discovered in 2009, and an IETF fix was proposed in [[!RFC5746]] which is widely implemented.</p>
+<p>If the Client does not send a certificate, because either it does not have one or it does not wish to send one, other authentication procedures can be pursued at the application layer with protocols such as OpenID, OAuth, BrowserID, etc... </p>
+<p>As far as possible it is important for the server to request the client certificate in <code>WANT</code> mode, not in <code>NEED</code> mode. 
+If the request is made in <code>NEED</code> mode then connections will be broken off if the client does not send a certificate. 
+This will break the connection at the application protocol layer, and so will lead to a very bad user experience.  The server should therfore avoid doing this unless it can be confident that the client has a certificate - which it may be because the client advertised that in some other way to the server.

+<h2>Verifiying the WebIDs</h2>
+<p>The <tref>Verification Agent</tref> is given a list of WebIDs associated with a public key. It needs to verify that the agent identified by that WebID is indeed the agent that controls the private key of the given public key. It does this by looking up the definition of the WebID. A WebID is a URI, and it's meaning can be had by dereferencing it using the protocol indicated in its scheme. </p>
+<p>If we first consider WebIDs with fragment identifiers, we can explain the logic of this as follows. As is explained in the  RFC defining URIs [[!RFC3986]]
+<blockquote>
+The fragment identifier component of a URI allows indirect identification of a secondary resource by reference to a primary resource and additional identifying information.  
+The identified secondary resource may be some portion or subset of the primary resource, some view on representations of the primary resource, or some other resource defined or described by those representations. 
+[...]
+The semantics of a fragment identifier are defined by the set of representations that might result from a retrieval action on the primary resource.
+</blockquote>
+
+<p>In order therefore to know the meaning of WebID containing a fragment identifier, one needs to dereference the resource referred to without the fragment identifier. 
+This resource will describe the referent of the WebID in some way. 
+If it says that the referent of the WebID is the agent that controls the private key of the given public key, then this is a  definite description that can be considered to be a definition of the WebID: it gives its meaning.
+</p>
+<p>The trust that can be had in that statement is therefore the trust that one can have in one's having received the correct representation of the document that defined that WebID. 
+An https WebID will therefore be a lot more trustworthy than an https WebID by a factor of the likelyhood of man in the middle attacks.</p>
+<p>Once that is proven then the trust one can have in the agent at the end of the TLS connection being the referent of the WebID is related to the trust one has in the cryptography, and the likelyhood that the private key could have been stolen.</p>
+<p class="issue">Add explanation for URI with redirect.</p>

 <h2>Processing the WebID Profile</h2>
 
-<p>A <tref>Verification Agent</tref> MUST be able to process documents in
-RDF/XML [[!RDF-SYNTAX-GRAMMAR]] and XHTML+RDFa [[!XHTML-RDFA]].
-A server responding to a <tref>WebID Profile</tref> request SHOULD be able
-to deliver at least RDF/XML or RDFa.
-The <tref>Verification Agent</tref> MUST set the Accept-Header to request
-<code>application/rdf+xml</code> with a higher priority than
-<code>text/html</code> and <code>application/xhtml+xml</code>. If the server
-answers such a request with an HTML representation of the resource, this SHOULD
-describe the WebID Profile with RDFa.
+<p>So the Verification Agent needs to fetch the document, if it does not have a valid one in cache.   <tref>Verification Agent</tref> MUST be able to process documents in RDF/XML [[!RDF-SYNTAX-GRAMMAR]] and RDFa in XHTML and HTML [[!RDFA-CORE]]. The result of this processing should be a graph of RDF relations that is queryable, as explained in the next section.</p>
+
+<p class="note">
+It is suggested that the <tref>Verification Agent</tref> should set the Accept-Header to request <code>application/rdf+xml</code> with a higher priority than <code>text/html</code> and <code>application/xhtml+xml</code>.  The reason is that it is quite likely that many sites will produce non marked up html and leave the graph to the pure rdf formats.
