<para>Got RDDL?</para>

<para xml:id='p1'>I continue (somewhat sporadically, I admit) to try to get
<link xlink:href="http://www.w3.org/2001/tag/doc/nsDocuments/">a
finding</link> about the
TAG issue
“<link xlink:href="http://www.w3.org/2001/tag/issues.html?type=1#namespaceDocument-8">namespaceDocument-8</link>” published.
</para>

<para xml:id='p2'>Last time the
<wikipedia page="Technical_Architecture_Group">TAG</wikipedia>
visited this issue, I thought we devised a
relatively straightfoward model of the information that is represented by
a <wikipedia>RDDL</wikipedia> document. There were some t's to be crossed
and some i's to be dotted, but it looked like we were approaching
closure.</para>

<para xml:id='p3'>The danger with leaving something untouched for months
is that when you come back to it, you basically have to start from
scratch. When we did, at the TAG face-to-face meeting last week, I was
startled to find adamant objection to the simple model we'd earlier
discussed.</para>

<para xml:id='p4'>Exploration revealed something much more complex.</para>

<para xml:id='p5'>I think I can see how that's a better model in some academic sense, but
I'm not sure it represents a practical way forward for the finding.
The finding just needs to ground a couple of alternate syntaxes in
some unifying model that's simple enough, and straightforward enough,
to be seen as obviously a way of modeling the information in the document.
</para>

<para xml:id='p6'>Not sure what else to do, I took an action to see what's
actually out there in the wild as far as RDDL use. In particular, I'm
curious about what syntaxes are actually used and what natures and
purposes people really employ.</para>

<para xml:id='p7'>Pointers, please.</para>
