{{short description|Certification by the Open Source Initiative}} '''The Open Source Definition''' ('''OSD''') is a document published by the [[Open Source Initiative]]. Derived from [[Bruce Perens]]' [[Debian Free Software Guidelines]], the definition is the most common standard for [[open-source software]]. The definition has ten criteria, such as requiring [[source-available software|freely accessed source code]] and granting the open-source rights to everyone who receives a copy of the program. Covering both [[copyleft]] and [[permissive license]]s, it is effectively identical to the definition of [[free software]], but motivated by more pragmatic and business-friendly considerations. The Open Source Initiative's board votes on proposals of licenses to certify that they are compliant with the definition, and maintains a list of compliant licenses on its website. The definition has been adapted into the [[Open Knowledge Foundation]]'s [[Open Definition]] for [[open knowledge]] and into [[open hardware]] definitions.
