Re: [vwrap] Call for a vote on interop BETWEEN independent virtual worlds or not

[Morgaine <[e-mail]>]

Barry, I too think that we are arguing something that we already agree on.
Joshua was undoubtedly right in his latest post, because after all we've
spent hundreds of emails discussing interop between virtual worlds in very
explicit terms, so it's close to impossible that this hasn't been our common
goal.  It must be an issue of terminology or emphasis.

I like the services approach to interop a lot, as it provides a high degree
of decoupling and very natural client-server architectures with which we
have huge experience in building and scaling.

However, our VW use cases are not expressed in terms of services, but in
terms of user-level concepts like virtual worlds, teleports, avatars, and
clothing.  Somehow we are going to have to examine our services-oriented
definitions and protocols in terms of the VW-oriented use cases to determine
whether we are on the right track and fulfilling our requirements.  This
requires us to accept that interop between VWs must be discussable, at least
when examining use cases.

I'm happy to accept that the bulk of our work will be in terms of services,
as long as the general goal of providing interop between virtual worlds is
clearly highlighted in the introduction.  Without that, readers will simply
have no idea what we're trying to achieve.  Besides that, we will have to
continue discussing how services relate to VWs (as we have been for many
months), because that provides us with our user-level requirements.

Beyond that, I think we can stick to the services view entirely.


Morgaine.
