Sad Story Timeline
• 1996 - Invented Sync-O-Matic (Real Media)• 1997 - 1999 Gave continuous talks / demos
at conferences• 1998 - Tried to commercialize product
through my job (It was the 90’s after all)• 1999 - Switched jobs (partially due to bitter
experience with intellectual property folks)• 1999-2001 Re-Invented the idea in
ClipBoard-2000 (Quicktime/Apple)

More Sad Story…
• 2001 - Switched jobs to the private sector to commercialize technology and deploy into the M.L.T.
• 2001 - Microsoft dropped M.L.T.• 2003 - Switched jobs again to work on
open source CLE (CHEF)

Anatomy of a Point Solution for T & L
• Point solutions are by nature deep explorations down a possibly fruitful path by a passionate person or small group.
• Hard to get traction because it is not a “complete” solution
• Often projects end up starving to death for lack of attention
• Often it is a situation where a poet is ahead of their time

Chuck’s Hierarchy of Sakai Goals
Stop developer-rich schools from writing a new CLE
Appeal to IT folks - get Enterprise installs
Broaden scope to cover basics
InteroperabilityBetween CLE’s
Innovation
We must learn to walk before we fly. And wemust start at the bottom and workupwards…
Sakai is about organizations - not individuals.

Safe base level functionality empowers new thinking, approaches, and standards, (i.e. good chaos). We enter a period of chaotic freedom.

Attacking the “Summit”
• We are only at “base camp”
• Standards and interoperability are the place where competitors must cooperate
• Vendor lock in is bad - Open Source lock in is even worse

Interoperability and Innovation
• Likely to happen– IMS Tool Interoperability– IMS Common Cartridge (IMS CP Interoperability)– IMS Enterprise Interoperability
• Just Plain Crazy– Live Data Interoperability– Service Oriented Architecture for User Interface
(SOAUI)

IMS Changes in 2006
• New CEO of IMS - Rob Abel• IMS is getting better - more open and more
accessible• Joel Greenberg of OU hosted a VLE
interoperability workshop attended by, Sakai, Moodle, Microsoft, and WebCT
• Alt-I-Lab renamed Learning Impact– Working on Open Source VLE track at IMS
Learning Impact next April

IMS Enterprise Interoperability
• The idea is to build on IMS Enterprise to make it truly interoperable
• Planned demonstrator next year at Learning Impact - April 2007

Sakai Interoperability: “Swiss Army Knife”

Data Interoperability 2009 *• Move from interoperability with a ZIP file
moving around by hand to a continuous dynamic interchange of fully modeled data between systems
• Use cases– Add a syllabus to Sakai and it immediately appears
in Dspace, Fedora, Moodle, WebCT, and Blackboard
– Synchronize to your desktop (PLE), work off line, and then reconnect
• This requires dramatically improved protocols
* This is a crazy idea :)
![Page 31: VLEs Going Forward Scanning the Horizon Charles Severance OS VLE Next Generation Workshop Cambridge June 29, 2006 This material is Copyright Creative Commons.](https://reader030.fdocuments.us/reader030/viewer/2022032800/56649d2a5503460f949fea7d/html5/thumbnails/31.jpg)
Crazy Idea: Interoperability at the User Interface
• Service Oriented Architecture at the User Interface (SOAUI)
• iTunesU is the model to follow until we find something better
• This collaboration, portfolio, learning, achievement, talent, etc - is about *ME*
• But not just about “ME” - I am a different me in different “context”
• So my “essence” is a combination of “who I am and “where I am plugged in”

Summary
• Sakai is “unfreezing” the LMS market in a number of important ways
• By gathering open source efforts together, we collectively “show up on radar”
• By solving the basics of the CLE space, Sakai provides a launch platform for true innovation in approaches to T & L
• By investing in standards efforts, Sakai insures the the forward progress will be across-the-board and not just for the adopters of Sakai
• Sakai must exemplify “not locking users in”
