The Open Source Landscape

“If you have the right attitude, interesting problems will find you”
— Eric S. Raymond, The Cathedral and the Bazaar

Open efforts and open source are a big part of how the spec and adoption have made it to where we are today. Without the involvement of everyone in the community, we all would be sad pandas — or at least less-interesting pandas. This post is a bit about open source in general, but mostly about the projects out there using the spec, from people across the community who deserve credit for their hard work.

What does it really mean when someone says xAPI is open source?

By nature, xAPI is intended to be used by everyone. It’s a specification that will become a standard. It’s not open source in the way most of us think of it: a piece of software being delivered with it’s source code. The main point is that the spec is open to everyone in the community who wants to be involved. The 1.0.0 specification has an Apache 2.0 license on it. That license makes the specification free to use, build on, redistribute, etc. It’s on GitHub where anyone who wants to contribute and grow the spec further is welcome to.

Open Source Licenses

There are a number of open source licenses out there. When you’re looking for open source software to use, you really do want to make sure there is a license on the project and make sure you know what that license means. It’s better to ask the owner than assume something is open source just because the code is publicly available. There are a few licenses used often in the projects I found. They’re mainly MIT, GNU and Apache 2.0. You can find out more about these licenses and others here.

Finally, here they are. These are open source projects, specs, experiments and prototypes from across the internet. I put a call out on twitter, on ADL’s mailing list and did some searches to gather these. If you have something to contribute, email me megan.bowe@tincanapi.com and I will add it.
