<div>Peter,</div><div><br></div><div>Just to be clear, we've been using metadata-driven protocol flows in deployment since at least 2002. I think the real progress and convergence here is giving users the ability to define their own trust relationships with services rather than requiring the IdP/OP and its administrators to do that. It's a key development which makes federated identity's UX issues much more difficult and urgent.</div><div><br></div><div>e.g. <a href="https://mail.internet2.edu/wws/arc/shibboleth-users/2003-06/msg00026.html">https://mail.internet2.edu/wws/arc/shibboleth-users/2003-06/msg00026.html</a></div><div><br></div><div>Thanks,</div><div>Nate.</div><br><div><div>On 19 Oct 2008, at 20:27, Peter Williams wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><p class="MsoNormal" style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif; "><b><span style="font-size: 10pt; font-family: Tahoma, sans-serif; color: rgb(31, 73, 125); ">But this is really irrelevant.
