<P class=MsoNormal><SPAN style="FONT-SIZE: 11pt; COLOR: #1f497d">Yes, that was my instinctive response to the suggestion to use UUIDs at TDWG. They are easy and may help, but they have distinctive disadvantages.</SPAN></P>

<P class=MsoNormal><SPAN style="FONT-SIZE: 11pt; COLOR: #1f497d">From a recent discussion with Tim, and having just been to the sem web conference (<A href="http://iswc2008.semanticweb.org/">http://iswc2008.semanticweb.org</A>) , I am also rather unsure about LSIDs in their pure form, in that they are not at all semantic web friendly - ie they cannot be resolved using default HTTP resolution. The idea of using the http proxy version of the LSIDs is a good way to get around this, but this does have some drawbacks:</SPAN></P>
<P class=MsoNormal><SPAN style="FONT-SIZE: 11pt; COLOR: #1f497d">- 1st you really need everyone to agree to use it everywhere, which is a bit difficult considering it is not at all part of the LSID standard, and we struggle to get "everyone" to do anything</SPAN></P>
<P class=MsoNormal><SPAN style="FONT-SIZE: 11pt; COLOR: #1f497d">- 2nd, it seems very much like a hack - you might as well just use permanent http urls - ie the main advantage of LSIDs in this case is the "encouraging a degree of thought before making URIs publically available". But we don't really need to pick up the whole LSID overhead just to achieve this.</SPAN></P>
<P class=MsoNormal><SPAN style="FONT-SIZE: 11pt; COLOR: #1f497d"></SPAN> </P>
<P class=MsoNormal><SPAN style="FONT-SIZE: 11pt; COLOR: #1f497d">So it seems to me like good old Plain Old URLs are just great! : -) </SPAN></P>
<P class=MsoNormal><SPAN style="FONT-SIZE: 11pt; COLOR: #1f497d">Or at least the suggestion of REST styled, permanent HTTP URLs as GUIDs ???</SPAN></P>

<DIV>
<P class=MsoNormal>I took a couple of days off but couldn't help thinking about GUIDs and UUIDs especially after the various discussion that were had in Fremantle. I have written these up in a blog here:</P></DIV>
