<p class='irc'><<cite>trackbot</cite>> Sorry, couldn't
find user - items</p>
<p class='phone'>Raphael to look into image maps spec re
spatial fragment shape</p>
<p class='phone'>image maps allow several different shapes</p>
<p class='phone'>there are two types of image maps: client-side
& server-side</p>
<p class='phone'>server-side image maps are done with queries
("?") but are not often used on the Web</p>
<p class='irc'><<cite>Yves</cite>> server-side image maps
were used back in 94/95, no longer now</p>
<p class='phone'>cleint-side image maps have as a draw-back the
problem that they cannot be indexed by search
engines</p><a name="action01" id="action01"></a>
<p class='phone'>the second action will be discussed during the
F2F and thus documentation created</p><a name="action03" id=
"action03"></a>

<p class='irc'><<cite>trackbot</cite>> ACTION-3 And Erik
to document container formats closed</p>
<p class='phone'>Silvia has sent a long email and a sketch on
how fragments and protocols can work</p>
<p class='phone'>she started with side conditions and then took
into account all the different standards (HTTP, proxy, URI)
that prvide restrictions</p>
<p class='phone'>Yves was to check the status of ';' in a
URI</p>
<p class='phone'>he sent an email and found that ";" basically
has the same restrictions as "?"</p>
<p class='irc'><<cite>Yves</cite>> ACTION-5 closed</p>
<p class='irc'><<cite>trackbot</cite>> ACTION-5 Check the
status of ';' in a URI closed</p>
<p class='phone'>he is not sure how many other applications are
using ";" for different purposes</p>
<p class='phone'>silvia mentions that we should check use of
whatever syntax we decide upon by checking existing usage</p>
<p class='irc'><<cite>Yves</cite>> <a href=
"http://www.ietf.org/rfc/rfc3986.txt">http://www.ietf.org/rfc/rfc3986.txt</a></p>

overlap</p>
<p class='phone'><cite>Silvia:</cite> CMML relevant from the
POV of naming segments in media files<br />
