> Description of Working Group:
>
> The working group will define the Virtual World Region Agent Protocol
> (VWRAP) for a collaborative 3-dimensional virtual environment. The
> protocol permits users to interact as digital representations called
> "avatars". An avatar exists in at most one location within a shared
> virtual space. Conforming client applications use the protocol to
> manipulate and move the user's avatar, create virtual objects,
> interact with other users and their surroundings, consume and create
> media and information from sources inside and outside their simulated
> environment.
>
> A virtual space can be partitioned into "regions" to facilitate the
> computational and communication load balancing required to simulate
> the virtual environment. A region provides the service environment in
> which inhabitants and objects can interact. A region uniquely
> represents a partition of the virtual space; they are not a mechanism
> for load balancing by having multiple instances of the same space.
> Different regions may be administered by different organizations. The
> state of a virtual world is independent of the client applications
> that access it and may persist between user sessions.
>
> Within a VWRAP virtual environment, services may be deployed by
> multiple organizations having varying policies and trust domains. The
> VWRAP protocol will provide the mechanisms for these services to
> interoperate, when permitted by policy. The working group may document
> examples of policies applicable to a VWRAP environment.
>
> Foundational components of the protocol include the publication of:
>
> * an abstract type system, suitable for describing the application
> protocol in an implementation neutral manner,
>
> * a security model describing trust relationships between
> participating entities,
>
> * guidelines for the use of existing authentication and
> confidentiality mechanisms,
>
> * an application-layer protocol for establishing the user's avatar
> in a region,
>
> * an application-layer protocol for changing an avatar's position,
> including moving between regions,
>
> * format descriptions for objects and avatars, and
>
> * an application-layer protocol for identifying entities, and
> requesting information about them.
>
> The protocol defined by this group will carry information about the
> virtual environment, its contents and its inhabitants. It is an
> application layer protocol, independent of transport, based partially

> * http://tools.ietf.org/html/draft-hamrick-ogp-intro
> * http://tools.ietf.org/html/draft-hamrick-llsd
> * http://tools.ietf.org/html/draft-hamrick-ogp-auth

> The protocol should describe interaction semantics independent of
> transport, leveraging existing standards where practical. It should
> define interoperability expectations for server to server interactions
> as well as client-server interactions. Though the protocol is
> independent of transport, early interoperability trials used HTTP(S)
> for non-real-time messages. The working group will define specific
> features that must be replicated in other transports and will define
> the use of HTTP(S) as a transport of protocol messages.
