The term Free Software is typically associated with software licensed under an FSF-approved license (The Free Software Definition), and the term Open Source (Software) is typically associated with software licensed under an OSI-approved license (The Open Source Definition).
Most of the applicable licenses are both, FSF- and OSI-approved. But there are exceptionsthere are exceptions. So
- not all Free Software is Open Source (Software),
- not all Open Source (Software) is Free Software.
Is there a term that includes both sets?
The alternative term FOSS, which stands for "free (and) open-source software", is, according to its Wikipedia article, for software that
can be classified as both free software and open-source software.
I guess that this applies also to FLOSS, which stands for "free/libre (and) open-source software".
