Summary: This session will give an overview of OpenSim, an open source multi-platform, multi-user 3D application server that can be used as an alternative to SecondLife. For campuses looking to develop a simulated "world" for teaching and learning, or for those looking for an alternative to SecondLife.

OPENSIM ALTERNATIVE TO SECOND LIFE
1. OPENSIM: A NEW ALTERNATIVE TO SECOND LIFE Chris M.

2. Today’s Learning Objectives Why did educators start exploring Second Life? What did we learn about using the platform for education? Is OpenSim a good alternative? What is it and how does it work? How do I participate in the USO Grid pilot?

34. Investment is tied to single platform Backing up a campus of thousands of objects is not an option in Second Life, moving it to OpenSim is extremely difficult, if possible at all (licensing, IP, ownership).

36. Pros and Cons of Second Life Pros Cons 24/7 virtual campus presence – great for distance learning, outreach, marketing Increasing Costs – Linden Lab cancelled educational discount program Higher retention in DL programs – Students feel more connected and engaged Lack of Content Portability – Hard to share or collaborate, content and investment is “stuck” in Second Life Improved learning outcomes – Simulations and roleplays increase learning No Transparency – Private company is not accountable to educators, very little leverage for changes we need Unique affordances no other platform provides - prototypes, data visualizations, meetings and conferences “feel” immersive Slow development cycle – Innovation has slowed (mesh) , major bugs yet to be addressed (group chat) Cost savings on physical infrastructure – Substantially reduces costs of meetings, conferences and potentially classrooms Uncertain Future – Seem to be moving towards more “social” uses of platform, less focus on enterprise use

53. Important Caveats! Issues with OpenSim OpenSim is in ALPHA stage – frequent updates mean things change often and sometimes radically. Not all features we’ve come to expect in Second Life work well or exist yet in OpenSim. Much of the content we’ve bought/used in Second Life will NOT be transferrable. OpenSim doesn’t have a well established content marketplace yet – have to make much of what we need. User community is still relatively small, miss some of the social aspects of Second Life with its plethora of places, people, and activities. But this will come in time!
54. USO Grid in Planning Phase April 2011 June 2011 August 2011 Currently testing system architecture options for scalability Working with OLN and OARnet to run USO Grid on Virtual Machines (hosted at OARnet) Goal: Grid Services up and running, test hosted and self-hosted config options Select institutions for pilot phase Goal: Regions ready for 2011-12 academic year for pilot institutions 0.7.1 release expected in Fall/Winter 2011 (?)
