Well, this is part of the same representation problem as usual... once
again, the general rule is:-

[[[
Not everything has a URI, as you can talk about something by just
using its properties. But using a URI allows other documents and
systems to easily reuse your information.

So you could represent Dan as an anonymous node:-

     [ a :Person; :name "Daniel W. Connolly";
        :hasHomepage <http://www.w3.org/People/Connolly/> ] .

But, as TimBL says "using a URI allows other documents and systems to
easily reuse your information", so that by giving these bunch of
properties a URI they become easier to reuse:-

     :DanC a :Person; :name "Daniel W. Connolly";
        :hasHomepage <http://www.w3.org/People/Connolly/> ] .

Blargh; it looks like you've reserved the right to use that URI to
identify the SW! Personally, I prefer the SW activity page [1], but
each to his or her own, I guess :-)
