Wikimedia Sverige continues its cooperation with the National Library of Sweden to bring more library data to Wikidata. In order to learn from each other's experiences, we invited a group of library employees to an all-day hackathon. The participants brought their expert knowledge of metadata and cataloging system, as well as an eagerness to learn more about Linked Open Data and Wikidata. We weren't surprised with their enthusiasm – Wikidata has been on the radar of librarians and information scientists for a while, as shown by initiatives like WikiCite, and the National Library of Sweden is working actively to increase the Linkedness and Openness of their data.
During the hackathon, we worked together on several ideas aimed at bringing Wikimedia and the library's union catalog Libris closer together, such as by including authors' Q numbers in the catalog. The participants also got to try their hand at editing Wikidata and writing more and more complex SPARQL queries.
