<p class=MsoNormal style='margin-bottom:12.0pt'>Perhaps, yet there is another
perspective. What constitutes the grid? In most technologies that have included
the now outdated semantic web and the more recent Web 2.0, the grid is more
distinct from the client. Web 3.0 is much different from Web 2.0. To describe
it in buzzwords, the semantic web has been ejected and the clouds have rolled
in. The grid, in Web 3.0 terms, may include several web apps found on various
websites, and the client may only be just the web browser (no special download
like Lively does). In order for those web apps to talk to each other without
one person logging in to all the websites, we can use OpenID. The web apps and
opensim together are what used to be the grid.<br>
<br>
Even if the sims aren't quite Web 3.0 at this time, there are standards being
made for it.<br>
<br>
More can be read here: <a
href="http://blogs.gnome.org/jamesh/2007/10/23/openid-20/">http://blogs.gnome.org/jamesh/2007/10/23/openid-20/</a><br>
And: <a href="http://www.axschema.org/">http://www.axschema.org/</a><br>
<br>
For example, RESTful calls from opensim can poll openid servers to initiate an
attribute exchange of avatar information. The user, also, can look and
change the avatar being referenced at the OpenID server, like maybe with a URL:
<a href="http://username.openid-example.com/avatar">http://username.openid-example.com/avatar</a>.
The OpenID most likely would not hold the actual data, but another web app
could provide the storage for the actual content. The reference of the avatar
at the OpenID server is just meta data, unless one wants to propose a standard
at <a href="http://www.axschema.org">http://www.axschema.org</a>.<br>
<br>
If OpenID was used in this way, then without even being in the 3D client, one
could buy clothes from one web app and transfer them over to another web app
that acts as the user's inventory. There is already development to allow such a
transfer with the current grid, but it still is based on a login to the grid
instead of OpenID.<o:p></o:p></p>
