AWG's mission is to develop the protocols that will open up the Second Life Grid from something operated solely by Linden Lab to where others can run parts of the grid.


The timeframe for this work is short.  Linden Lab is committed to implementing and deploying the protocols over the next two years.  In this time frame, the AWG must focus on those aspects of the protocol that enable the opening up of the grid while primarily keeping the remaining feature set of Second Life constant.


Since we all hope that this work forms a stable base for years to come, the AWG should endeavor that its designs support a variety of implementation strategies, and are amenable to future extension. There is a tension between an agile strategy of implementing only what you need today vs. the approach of designing for a range of future possibilities.  Linden Lab has heavily leaned toward the agile approach.  The AWG needs to lean mostly this way as well, with of course some thought given to making the protocol evolvable.

The AWG isn't meant as a wholesale redesign of the Second Life platform.  While we realize that there are many possible design choices, and that there are many possible approaches, the goal here is to take what is clearly a workable design and make it open.  Think HTML 1.0 and HTTP 0.9 - Neither were perfect, and there were many things that couldn't be done with them.  But they were functional, open and had enough extensibility to support future HTML versions, CSS, JavaScript, etc.... making the web what it is today.  The AWG must aim to do the same for virtual worlds, and realize it within the next two years.

__TOC__
Please Note:
* The draft page is locked because we want a stable reference for discussion and to base the next draft on. Each section in the draft has a link on the right to a discussion for that particular section.  Discuss!
* Previously, we referred to this document as "Second Life Grid Open Grid Protocol" or "SLGOGP." This has now been shortened to "Open Grid Protocol," but you may see the old terms on some documents and links.


==Goal==
=== Design Documents ===
The current state of the group's design:


Discuss, design and implement a scalable and open architecture for the future Second Life Grid.
* [[Second Life Grid]]: Description, motivation and goals.
** [[Architectural Principles]]
* [[Structural Design]]: Overview of structure, description of agent and region domains, etc.
** [[Agent Domain]]
** [[Region Domain]]

** [[Second Life Grid Protocols/Foundation|Foundation Protocols]]
** [[Login Protocol]]
** [[Teleport Protocol]]
*** [[SLGOGP_Teleport_Strawman | Teleport Strawman]]
* [[Second Life Grid Glossary]]


Create an architecture and set of specifications which will form the basis for:
=== Resources ===
* [[Open Grid Public Beta]]: Beta testing for login and teleport between Second Life and participating OpenSim simulators
* [[Pyogp|AWG Test Harness]]  Python-based client library and test harness to test implementation and documentation of the Open Grid Protocols
* [[AWG Use Cases]] contributed by work group members.


* The next generation SecondLife Grid
* World Wide Web scale hosting of Virtual World Content
* Multiple inter-operable implementations of the complete architecture (Metaverse creation)
* Allowing Individuals and Enterprises to host content, agents and virtual land
