Culture Heritage and Structured Data: How DPLA became the biggest institution to contribute to Structured Data on Commons – Diff

"What would become of Wikipedia and its sister projects without images from museums, libraries, and archives? Pictures from these institutions are able to illustrate a range of different articles, in diverse fields and areas. However, in order to really accomplish that, images should not only be available, but also enriched with data that can make them more findable on the projects. 

And so, for the past few years, the Culture and Heritage team at the Wikimedia Foundation has been involved with Structured Data-related initiatives in order to engage heritage materials on the Wikimedia projects. Our objective, together with the Structured Data Across Wikimedia (SDAW) team, was to support and increase image usage across the projects, as well as to structure Wikimedia to help it reach communities globally.

One of the main projects we worked on together was the initiative with the Digital Public Library of America (DPLA). This institution became one of the biggest Wikimedia Commons contributors, with 3.7 million images available on the project, by not only being the main institution in the United States directly uploading files to the platform, but also because of its structured data activities. Since 2020, DPLA has worked on adding and modeling structured data and engaging in discussions around the topic, precisely to make its files (the files from the 300 institutions that contribute to the DPLA’s Wikimedia pipeline) more findable and used on Commons, on Wikipedia, and elsewhere. Currently, DPLA presents around 15 million edits to 50-100 million structured data on Commons statements...."
