Main article: Creative Commons jurisdiction ports
The original non-localized Creative Commons licenses were written with the U.S. legal system in mind, so the wording could be incompatible within different local legislations and render the licenses unenforceable in various jurisdictions. To address this issue, Creative Commons asked its affiliates to translate the various licenses to reflect local laws in a process called "porting."[14] As of July 2011, Creative Commons licenses have been ported to over 50 jurisdictions worldwide.[15]
The latest version 4.0 of the Creative Commons licenses, released on November 25, 2013, are generic licenses that are applicable to most jurisdictions and do not usually require ports.[16][17][18][19] No new ports have been implemented in version 4.0 of the license.[20] Version 4.0 discourages using ported versions and instead acts as a single global license.[21]
