In that case I would suggest using a type 1 UUID (based on MAC address and time stamp) rather than the type 4 (completely random) that is normally used.<br><br><a href="http://en.wikipedia.org/wiki/Universally_unique_identifier">http://en.wikipedia.org/wiki/Universally_unique_identifier</a><br>

Hence, it's an important design decision.<br>

Question:<br>
<br>
Will this provide the groundwork for global content identification/creator attribution?<br>

I'm about to introduce global identifiers, so that I can make<br>
friends and IM work on the hypergrid, and would like feedback on the<br>
best form of these identifiers. Here are some options:<br>
<br>
<a href="http://myworld.com:8002/7c4450fc-aeaf-468d-b238-d52955dc868b" target="_blank">http://myworld.com:8002/7c4450fc-aeaf-468d-b238-d52955dc868b</a><br>
<br>
<a href="http://myworld.com:8002/7c4450fc-aeaf-468d-b238-d52955dc868b" target="_blank">myworld.com:8002/7c4450fc-aeaf-468d-b238-d52955dc868b</a><br></div>
<<a href="http://myworld.com:8002/7c4450fc-aeaf-468d-b238-d52955dc868b" target="_blank">http://myworld.com:8002/7c4450fc-aeaf-468d-b238-d52955dc868b</a>><div class="im"><br>
<br>
<a href="http://myworld.com:8002/user/7c4450fc-aeaf-468d-b238-d52955dc868b" target="_blank">http://myworld.com:8002/user/7c4450fc-aeaf-468d-b238-d52955dc868b</a><br>

...<br>
<br>
In this particular case (for friends and IM) we're dealing with user<br>
accounts, but the issue is broader than that. Whatever form we<br>
choose should be applicable to all sorts of resources.<br>
<br>
My preference is to use a URI, according to the spec of URIs<br>
(<a href="http://www.w3.org/Addressing/URL/uri-spec.html" target="_blank">http://www.w3.org/Addressing/URL/uri-spec.html</a>). The question is:<br>
should we add additional specifications on these URIs? Like using<br>
the path /user/ for user accounts, etc.<br>
<br>
Thoughts?<br>
<br>
Thanks.<br>
