> “Open means anyone can freely access, use, modify, and share for any purpose (subject, at most, to requirements that preserve provenance and openness).” - [The Open Definition](https://en.wikipedia.org/wiki/The_Open_Definition)

Open Source Dharma lineages **openly share teaching content**, in a way that conforms to the standard above, which itself comes out of the open source software movement.

The “most open” [Creative Commons Licenses](https://en.wikipedia.org/wiki/Creative_Commons_license) meet this definition. With these licenses one can share content openly to the public domain, the most open possible license, and/or can require attribution (provenance), and/or require that others share any derivative content under a similarly open license, known as share-alike or copyleft.
