What is Open Source?➡ Basically, it’s a “new” way to develop, license and distribute code ➡ Actually, there was “open source” even before it was called that ➡ The key technologies behind the Internet and the Web and the
Cloud are all Open Source based ➡ Brings Scientific Method to IT

What is Open Source?➡ Open Source Licensing
➡ OSI and/or Free Software Foundation (FSF) Approved
➡ Free Software ➡ As in Free Speech, not Free Beer
➡ Open Source Methodology (secondary) ➡ Community/Governance types ➡ Many consider this just as important as the license
This work is licensed under a Creative Commons Attribution 3.0 Unported License.
What is Open Source?➡ Also called Free Software
➡ But the word “Free” confuses some people
➡ FOSS: Free and Open Source Software ➡ FLOSS: Free/Libre Open Source Software ➡ Pretty much, all mean the same thing ➡ The name can cause “religious” or “philosophical” debates, but
in government and industry, Open Source is the more widely used term.

What is Open Source?➡ Basic tenets (related to licenses):
➡ Access to the source code (the code is Open and Free) ➡ Ability to use the source code (run it and/or leverage it) ➡ Ability to modify the source code ➡ Ability to distribute the (modified) source code
➡ Open Source “methodology”/philosophy

The draw of Open Source (hacker)
➡ Having a real impact in the development and direction of IT ➡ Personal satisfaction: I wrote that! ➡ Sense of membership in a community ➡ Sense of accomplishment - very quick turnaround times ➡ Developers and engineers love to tinker - huge opportunity to do
so

The draw of Open Source (Companies/Orgs)➡ Having a real impact in the development and direction of IT ➡ Sense of membership in a community (most of the time) ➡ Save on expensive resources ➡ Ability to focus on what differentiates yourself ➡ Allows for nimbleness and agility ➡ Increased revenue and market share
This work is licensed under a Creative Commons Attribution 3.0 Unported License.
The draw of Open Source (users)
➡ Access to the source code ➡ Avoid vendor lock-in (or worse!) ➡ Much better software ➡ Better security record (more eyes) ➡ Much more nimble development - frequent releases ➡ Direct user input ➡ Open Standards

Licenses
This work is licensed under a Creative Commons Attribution 3.0 Unported License.
Why?➡ Copyright is the default ➡ Open Source is everywhere ➡ The license determines use, re-use and distribution ➡ Not understanding means risk
This work is licensed under a Creative Commons Attribution 3.0 Unported License.
License Goals➡ Ensure what parts remain open source ➡ Maintain control over code and direction ➡ Provide common implementation for standards ➡ Build community or commercial marketplace ➡ For most end-users, this is the sole touch-point
This work is licensed under a Creative Commons Attribution 3.0 Unported License.
True Open Source➡ For software to be Open Source, it must be under an OSI or
FSF approved Open Source License ➡ Open Source Definition: http://www.opensource.org/docs/osd ➡ Free Software Definition: http://www.gnu.org/philosophy/free-
sw.html ➡ New Open Source licenses are very hard to get approved ➡ There are really 3 main types

One True License➡ There is no such thing ➡ Licensing is selected to address what you are trying to do ➡ In general, Open Standards do better with AL-like license ➡ If wide adoption is important to you: again AL. ➡ To restrict non-shared enhancements: copyleft

Governance/Community

Community➡ AKA: Governance
➡ Defines how the community operates ➡ How conflicts are resolved ➡ Growth path of the community
➡ code ➡ members
➡ Again, 3 main types
