Linden Lab and IBM Collaboration on Virtual Standards



With virtual worlds now firmly embedded in popular culture, the virtual landscape may seem like an archipelago with Second Life, There, Active Worlds, Doppelganger, Multiverse, Kaneva, and many more. Sailing between these isolated little islands is possible, but the voyage is daunting.

One of the earliest sailors willing to make the journey was Wells Fargo who, after creating their virtual presence in Second Life, decided to pack up and move to Active Worlds. While I'm not privy to the details of their migration, I can surmise that the textures were transported to Active Worlds by hand while the geometry data was either exported via scripts so that it could be generated from within Active Worlds, or simply re-built from scratch. Long story short, it wasn't an effortless transition.

Well all that may be changing with a recent announcement that Linden Lab and IBM will be working together on standards to bridge the gaps between virtual worlds. The announcement included several areas of focus with the overarching theme that users will one day be able to move freely between virtual worlds including "Universal" Avatars, Security-Rich Transactions, Platform Stability, Integration with existing Web and business processes, and Open standards for interoperability with the current web.

Possibly the most inspirational quote from the announcement was:

"Open standards in this area are expected to allow virtual worlds to connect together so that users can cross from one world to another, just like they can go from one web page to another on the Internet today."

So how would this all work? I envision some sort of intermediary standard for geometry, texturing, and interactive scripting. When an avatar crosses a virtual world border, it will be translated into this intermediary standard and then passed along to the destination virtual world (all while they inspect your passport and search your luggage for contraband.) The destination world will read the data and translate it into the local formats necessary to render the avatar. Edges of virtual regions may be encoded with destination information much like Second Life SLURLs so that the appropriate virtual world client will launch as you make your transition.

Perhaps one interesting side effect of all this could be the different ways different platforms will "interpret" your avatar. The intermediary data that defines the Aimee Weber avatar may look photo realistic in Second Life, while looking cartoonish in IMVU (and I would love to see how Aimee looks in a Picasso based virtual world!)



Here's another biggie:"Collaborating on the requirements for standards-based software designed to enable the security-rich exchange of assets in and across virtual worlds."

Asset management has always been one of the biggest challenges for Linden Lab because it's difficult (perhaps impossible) to maintain asset control and performance on a distributed system. Therefore Second Life has implemented one asset server to keep an eye on what we have, who we give it to, and what the next owner is allowed to do with it. So where does a second, third, or thirtieth asset server fit in all this?

One idea would be that those cool boots you bought in Second Life will be converted to the intermediary data along with your avatar, and then passed to the destination world's asset server. This is more complex than surfing from website to website for a number of reasons. The limbo-like area between virtual worlds will be a great place to lose assets if the transaction system is not air-tight. As many Second Life residents lament, disappearing assets in Second Life are a constant problem. Now imagine working with the technical support departments of two or more separate companies in hopes of tracking down your lost boots while each one is blaming the other for the glitch ... naturally!

Trust is another important issue. When we move from one virtual world to another, we will be passing valuable virtual assets to the destination in hopes that they will play by the rules and not simply take copies of all our stuff! This means that each virtual world company will have to keep tight reins on which other virtual worlds may serve as destinations from their own location. In fact, consortiums of virtual worlds will have to come to unanimous decisions as to which virtual worlds can be trusted to "join the club" because it would take only one bad virtual world plugged into a consortium to place the assets of the entire collective at risk.

Finally there's this quote:
"Allowing current business applications and data repositories - regardless of their source - to function in virtual worlds is anticipated to help enable widespread adoption and rapid dissemination of business capabilities for the 3D Internet."

So the plan isn't just to bridge the gap that separates virtual world from virtual world, but also the gap that separates virtual world from the existing web and database structures used in business today. One may recall Daden, the UK metaverse company that created a 3D visualization demo of live flight data inside of Second Life as well as Aimee Weber Studio's live 3D weather visualization map for the National Oceanic and Atmospheric Administration. These demos were cool, and arguably useful, but what is missing is the ease-of-use that businesses come to expect from data visualization tools available with Excel.

So what will we expect to see? I imagine there will be one massive virtual collective that emerges with mainstream goals. Competition will still exist between virtual worlds, but without the isolation we currently see. The question of which platform a corporation or organization should choose for their virtual presence will become less important. Smaller, isolated collectives may emerge from countries like China who wish to keep tighter controls over, well, everything. I'm also looking forward to the tiny, subversive, anti-establishment collective that will undoubtedly emerge.

What IBM and Linden Lab are setting out to do is ambitious, and ultimately very cool. There is a long road ahead, but I think it's safe to say that we're now starting to see the water levels recede and the archipelago slowly merging into a single, rich and diverse land mass.
