+<h2>The WebID Profile</h2>
+
+<p>The <tref>WebID Profile</tref> is a structured document that contains 
+identification credentials for the <tref>Identification Agent</tref> expressed 
+using the Resource Description Framework [[RDF-CONCEPTS]]. The following 
+sections describe how to express certain common properties that could be used
+by <tref>Verification Agent</tref>s and other entities that consume a 
+<tref>WebID Profile</tref>.</p>
+
+<p>The following vocabularies are used in their shortened form in the 
+subsequent sections:</p>
+
+<dl>
+  <dt>foaf</dt>
+  <dd>http://xmlns.com/foaf/0.1/</dd>

+information but are NOT REQUIRED to be present in a WebID Profile:</p>
+

+<h2>Cryptographic Details</h2>
+
+<p>Cryptographic details are important when <tref>Verification Agent</tref>s
+and <tref>Identification Agent</tref>s interact. The following properties 
+SHOULD be used when conveying cryptographic information in WebID Profile
+documents:</p>
+
+<dl>
+  <dt>rsa:RSAPublicKey</dt>
+  <dd>Expresses an RSA public key. The RSAPublicKey MUST specify the
+  rsa:modulus and rsa:public_exponent properties.</dd>
+  <dt>cert:identity</dt>
+  <dd>Used to associate an RSAPublicKey with a WebID URL. A WebID Profile
+  MUST contain at least one RSAPublicKey that is associated with the
+  corresponding WebID URL.</dd>
