Open Source does not simply mean that the source code of a project is available, which is only one element of an Open Source project. The Open Source Initiative (OSI) provides a commonly accepted definition of what constitutes Open Source. To summarize that, in order to be considered Open Source:
- Open Source Software needs a license,
- a work has to allow free redistribution,
- the source code needs to be made available,
- it must be possible to create further works based on it,
- there must be no limitations of who may use the work or for what purpose (so something like “no commercial use” or “no military use” won’t work with Open Source),
- the work must not require an additional license on top of the one it comes with,
- and finally, the license must not depend on a specific distribution format, technology or presence of other works.
