OSD
Noun · Open Source
Definitions
Short for the Open Source Definition, the criteria used to determine whether a software license qualifies as open source. In licensing culture, OSD compliance is a key distinction between truly open licenses and source-available terms that keep important restrictions.
In plain English: Short for the Open Source Definition.
Example: "The maintainers argued that the new terms were not OSD-compliant, so calling the release open source would have been misleading."
