The Duncan Segregation Index is a measure of occupational segregation based on gender that measures whether there is a larger than expected presence of one gender over another in a given occupation or labor force by identifying the percentage of employed women (or men) who would have to change occupations for the occupational distribution of men and women to be equal.
 A Duncan Segregation Index value of 0 occurs when the share of women in every occupation is the same as women's share of employment as a whole.
 In other words, 0 indicates "perfect" gender integration within the workforce, while a value of 1 indicates complete gender segregation within the workforce.
Creative Commons (CC) is an American non-profit organization devoted to expanding the range of creative works available for others to build upon legally and to share.
 The organization has released several copyright-licenses known as Creative Commons licenses free of charge to the public.
 These licenses allow creators to communicate which rights they reserve, and which rights they waive for the benefit of recipients or other creators.
 An easy-to-understand one-page explanation of rights, with associated visual symbols, explains the specifics of each Creative Commons license.
 Creative Commons licenses do not replace copyright, but are based upon it.
 They replace individual negotiations for specific rights between copyright owner (licensor) and licensee, which are necessary under an "all rights reserved" copyright management, with a "some rights reserved" management employing standardized licenses for re-use cases where no commercial compensation is sought by the copyright owner.
 The result is an agile, low-overhead and low-cost copyright-management regime, profiting both copyright owners and licensees.
 Wikipedia uses one of these licenses.

Learning commons, also known as scholars' commons, information commons or digital commons, are learning spaces, similar to libraries and classrooms that share space for information technology, remote or online education, tutoring, collaboration, content creation, meetings and reading or study.
 Learning commons are increasingly popular in academic and research libraries, and some public and school libraries have now adopted the model.
