<h4>Goals:</h4>

<li>review state of the art in URI schemes vs other extensibility points such as MIME types</li>

  <li>
    <a href="http://lists.w3.org/Archives/Public/www-tag/2008Oct/0002">mnot 2 Oct</a> raises this to the TAG:
	<blockquote>Looking through the TAGs findings, I think most of
the relevant documents are too dense to be useful to developers like
this.</blockquote>

    <a href="http://lists.w3.org/Archives/Public/www-tag/2008Oct/0009.html">mnot again</a>

    <blockquote>
      <p>...media types have a well-known limitation in that they need to be
implemented server-side, which often requires coordination between the
author and a server administrator. URI schemes, from the author
standpoint, "just work", and arguably there are many many more authors
than client application developers in the world, so it's appropriate
to push the pain onto the smaller and more capable party.</p>

<p>Just playing devil's advocate, you understand. If we don't pay
attention to these kinds of trade-offs, we'll find the architecture
roundly ignored, perhaps rightfully so.</p>
