<h3>Presentation Materials and Meeting Records</h3>
|
|
|
|
<p>Presentation materials are part of the meeting record, and accessible
|
|
meeting records are important.</p>
|
|
|
|
<p>A few WG members have requested that presentation materials be available a
|
|
couple days ahead of time. An easy way to submit them to the record without
|
|
clogging up everybody's mailbox is to mail them to
|
|
<tt>www-archive@w3.org</tt> as attachments, then find them in the <a
|
|
href="http://lists.w3.org/Archives/Public/www-archive/">archive</a>, and send
|
|
a pointer to <tt>public-rdf-dawg@w3.org</tt>.</p>
|
|
|
|
<p>The <a
|
|
href="http://www.w3.org/2002/03/email_attachment_formats.html">guidelines for
|
|
email attachments</a> are relevant:</p>
|
|
|
|
<blockquote>
|
|
<p>...avoid formats that are virus prone, proprietary or platform
|
|
dependent. For example, whenever possible you should use HTML instead of MS
|
|
Word, PowerPoint or PDF. (Ideally, use XHTML or HTML4.)</p>
|
|
|
|
<p>If you must use a proprietary or platform-dependent format, please also
|
|
include an alternate version in a universally readable format, such as HTML
|
|
or plain text, if possible. If you cannot, then at least include a format
|
|
that has widely available free viewers, if possible.</p>
|
|
</blockquote>
|
|
|
|
<p>If you use powerpoint, please give us the powerpoint sources plus a PDF
|
|
export plus some sort of text dump (RTF?).</p>

|
|
<p>Connolly briefly reviewed <a href="/Consortium/Process/">W3C
|
|
process</a>, emphasizing that its purpose is to build community
|
|
consensus to deploy new technologies. Connolly noted that changes to
|
|
the <a href="http://www.w3.org/2003/12/swa/dawg-charter">charter</a>
|
|
are possible, but they involve negotation with parties outside the
|
|
WG.</p>

<h3 id="ucr">Use Cases</h3>
|
|
|
|
<p>Connolly noted that outreach is an important function of the use
|
|
cases and requirements document; for example, it would be nice to note
|
|
a few use cases in a short summary of our work for the WWW2004
|
|
conference.</p>
|
|
|
|
<p>Each member of the WG was invited to speak briefly to their most
|
|
valued use cases and the connection to their work and their
|
|
constituency. <em>see <a
|
|
href="http://www.w3.org/2004/04/22-dawg-irc">IRC log</a> for some
|
|
details</em>.</p>
|
|
|
|
<p><b>ACTION DaveB:</b> write up this educational metadata UC</p>
|
|
|
|
<p>Clark reported on the current (1.24) use cases draft: some
|
|
struggles with the "benefits" heading and such.</p>
|
|
|
|
<p>The group discussed the balance between quality and quantity of use
|
|
cases: how many do we have time to write up well? Opinions varied from
|
|
5 to 10 to 15. Some sentiment favored a small number of elaborated use
|
|
cases and a larger number of short sketches. External feedback might
|
|
prompt us to reconsider which use cases to elaborate.</p>
|
|
|
|
<p>The group discussed wasy to improve the document, including promoting the "problem description" material in the introduction.</p>
|
|
|
|
<p><b>ACTION RobS:</b> to generate some RDF (in some form) for 5.1.1.</p>
|
|
|
|
<p><b>ACTION EricP:</b> to generate a diagram of a query discussed in

<p><b>ACTION Kendall:</b> to work with Alberto on 5.1.3.</p>

|
|
<p><b>ACTION Yoshio:</b> to write up "Kate finds an article and wants

|
|

<p>ACTION Kendall: to recast this (5.2.1. Saying things about web
|
|
resources) in terms of some tool for annotating photos. (<b>DONE</b>
|
|
in 1.25)</p>
|
|
|
|
<p>ACTION Kendall: to add negotiation of query lang to
|
|
candidate requirements. (<b>DONE</b> in 1.25)</p>
|
|
|
|
|
|
<p>The group discussed requirements, especially their
|
|
relationship to use cases that motivate them.</p>
|
|
|
|
<p>The discussion got into some design details about styles of query
|
|
result bindings.</p>
|
|
|
|
<p>The group discussed requirements for support of various
|
|
forms of datatyping in some depth. We began collecting
|
|
<a href="ftfreq">straw poll data about support for
|
|
various requirements</a>.</p>
|
|
|
|
<p>Connolly constructed straw polls:</p>
|
|
<ul>
|
|
<li>if we were to keep only 5 use cases, would this be one of them?</li>
|
|
<li>if we were to keep only 10 use cases, would this be one of them? <em>this second question was abandoned part way thru.</em></li>
|
|
</ul>
|
|
|
|
<p>The <a href="http://lists.w3.org/Archives/Public/public-rdf-dawg/2004AprJun/0175.html">results as reported by Beckett</a> include:</p>

|
<p>The straw polls do not take into account the following use cases,

|
which had not been digested into the use cases document or, in some

cases, not been written:</p>

|
need to publish in May; May 17, the start of the WWW2004 web

conference, is an interesting, if challenging, target.</p>
|
|
|
|
<p>On Friday morning, the editor reported some progress

on updating the document (Revision 1.25 2004/04/23 08:13:40).

<p>As discussion of datatype constraints brought up some

short, and you will eventually need to know this material in order to

participate effectively in this WG, but since they don't directly relate to

decisions on the meeting agenda, none of them is required.</p>
