<p class="MsoNormal"><span style="color:black"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black">Based on last week’s meeting, I I think we are aiming for something like:<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:black"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black">If we say:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black">"Thin data elements must be accessible without requestor authentication"<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black">then that means consumers of registration data might or might not be anonymous.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black">For example, a registry operator could make me register my IP address, from which I can query registration data. Those queries could be made without authentication (a username/password), and so the registry’s
registration program could be allowed. But arguably I would not be anonymous. <o:p>
</o:p></span></p>
<p class="MsoNormal"><span style="color:black"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black">Whatever policy language is proposed must be examined for how it can be interpreted and possibly bypassed. Both the intent of the WG and the specific language will eventually need to be laid out.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black">So I also suggest it be made explicit that access to registration data remain free, without charge.
