What is Open-Source

1. Open Source software is open to the end user, making it technically and legally feasible to access and modify the code.

2. Open Source software is licensed under a form of copyright that provides the end user with the legal right to alter and redistribute the code.

OTIS Online is an ongoing effort to develop and share tools that make learning a more powerful experience. OTIS projects are usually built with free opensource software and liscenced under a General Public Liscence (GPL). Open Portfolio and CaseMate are the two flagship applications that represent this project, but others are on the way.

Code Customization Continuum
Level	Description
1	Neither content nor authoring environment is open-source
2	Authoring environment is open-source, but the content is propritary. (e.g. If we developed the Teacher Ed Tools in PHP, but tried to keep how we did it a secret. I call this the coca-cola method. The ingredients are know but how you put them together is not to be shared)
3	Content is open-source but authoring environment (e.g. learner based tools written in flash)
4	Both authoring environment and content are open-source (e.g. Open Portfolio is written in PHP and the source code is available)
