We added SDC statements to about 1,000 photos from the UNESCO Archives.
Enriching valuable material with SDC enables users to find it more easily, as well as gain additional insight about it.
Roger Caillois, one of the historical persons depicted in the UNESCO Archives.Wikimedia Sverige has an ongoing partnership with the UNESCO Archives. The institution has been putting a lot of effort into digitizing their materials, so that the world can learn more about its history and the work they have been doing around the world. We have uploaded a number of photographs from their collections to Wikimedia Commons, which has been received with great interest by the community, as the photos make a great addition to Wikipedia articles in several languages. What makes the photos particularly valuable is that they were taken in various places all around the world and that some of them depict historical events and persons – such as this portrait of Roger Caillois (Q430765), Chief of Literature Section at the UNESCO Division of Arts and Literature. The metadata that UNESCO extracted from their database usually included information about where the photos were taken and whom they depict. That's why we prioritized converting this data to SDC statements.
The following visualisation shows the results of this work, plotting the geographical location of the photos that contain the statement collection (P195)UNESCO Archives (Q106492651). This property provides an easy way of identifying files shared by a GLAM institution, even if they were uploaded by different users and organized in several categories. Querying for them is much more flexible than relying on the category system, as users uploading files independently might not be aware of existing category structures, leading to the photos being "invisible" to those who wish to explore the entirety of a GLAM's contribution to Wikimedia Commons.
