Slide 8:  What ‘open source’ means...

• Software is knowledge that is freely shared
  • Software distributed w/ source code
    • Linux, MySQL, Apache
• Copyrighted, Perpetual free license
• Maintained by a community
• No warranty

Results in...

• Little or no acquisition costs
• Collaborative development model
  • Peer review of code
• Shared costs and risks
• Reduces customer “lock-in”

[This slide contains two logos for open source.]

Slide 9:  What is IRIS?

• Integrated Roadway Information System (IRIS)
  • Advanced Transportation Management System (ATMS)
• Developed in-house by Minnesota DOT
• Looking for partners to maintain and evolve
