Each Wikimedia project has its own culture consisting of values which are commonly shared across Wikimedia and also some which have evolved which are specific to that particular project. These variances may be attributable to the different purposes, such as the distinction between a wiki-dictionary as opposed to a wiki-university, the latter emphasizing creativity whereas the former may emphasize accuracy. Other differences may be attributable to differences between linguistic communities or peculiar accidents in the history of a particular project, each of which consists of individuals with different perspectives. Precedent in wiki project arbitration of disputes may differ in different projects, which might thereby have diametrically opposed policies. In most cases, however, there are broad similarities in wikimedia culture and etiquette, and the use thereof.
