Live Performances VAG

: This is an early draft so scope and focus are still fairly open. Please add comments to the Talk:Live Performances VAG if you have slightly different concerns so that we can try to converge on a common viewpoint. This discussion could also expose other similar VAGs that are needed in this area.
= Purpose =
The Live Performances Viewpoint Advocacy Group exists to provide input to the architectural design process to satisfy the concerns of stakeholders involved with live performances on this platform.
This is a non-technical VAG expressing end-user perceptions and concerns, and focusing on use cases.
See the Architecture Working Group and the Viewpoint Advocacy Groups for more information.
=== Areas addressed by this viewpoint ===
* Identifying the main categories of live performance in virtual worlds.
* Identifying concerns that are of special interest in live performances.
* Defining current metrics and expected growth trends for live performances.
* Identifying the main obstacles to successful live performance.
* Proposing ways and means of overcoming such obstacles in the future system.
* Proposing means of assessment to ensure that such obstacles are being overcome.
=== Areas not addressed by this viewpoint ===
To be specified.
 
= Source of Viewpoint =
No existing sources for this viewpoint have (yet) been sought. This viewpoint is however highly reusable, and therefore existing sources are very likely to exist and should be investigated.
= General concerns addressed by this viewpoint =
* (general ones go here)
* See also Event Scalability VAG.
= Specific concerns within this viewpoint =
Here we define the specific concerns relevant to live performance.
=== Miscellaneous concerns (brainstorm) ===
The concerns expressed in this section do not need to be reconciled with each other at this stage.
* Observation: live performances in SL often have several component parts which bear differing relationships to the SL system:
:* a 3D visual component implemented entirely within the SL world (observable objects)
:* one or more components that are mapped onto a presentation within SL (eg. video displays)
:* one or more components that are largely independent of SL except in perception (eg. sound).
: Since a live performance usually attempts to integrate all of its elements into a live experience, the concerns expressed in this viewpoint will necessarily involve more than one single area of interest, and will therefore generate many cross-cutting requirements. This is inherent in the medium.
* Audiences currently suffer the following problems at, or in respect of, live performances:
:* Lag at all such events
:* Inability to enter popular live performance regions despite plenty of room visually
:* Invisibility of objects on arrival despite bandwidth being available but unused.
:* Personal inability to limit local problems such as unwanted visual or physical effects
* Performers currently suffer the following problems at live performances:
:* Lag
:* Audience figures artificially limited, ie. not limited through lack of interest.
:* Performance disruptions through platform failures
:* Performance disruptions through inability to limit abuse
:* Inadequate avatar controls severely limit visual performance
* Everyone wants this fixed:
:* Lag
=== Focused concerns ===
This section refactors the key issues expressed earlier into cohesive concerns which can more easily be turned into actual system requirements addressing the perspective of this viewpoint.
= Use Cases =
= Proposals and Analysis =
= Methods of evaluating conformance with viewpoint concerns =
Successful handling of Live Performance concerns can be assessed by partitioning the evaluation across several fronts:
* Client-side evaluation: TBD.
* Server-side evaluation: see Event Scalability VAG.
