A restriction, as part of a licence, that content cannot be freely re-used for ‘commercial’ purposes. Content or data subject to a non-commercial restriction is not open, according to the Open Definition. Such a restriction reduces economic value and causes problems with licence mixing, as well as often ruling out more than is intended (for example, it is often unclear whether educational uses are ‘commercial’). The intent of a non-commercial clause may be better captured by a share-alike requirement. See also → Licences.
