A Network of Places: Open Linked Building Data as Research Infrastructure is a collaborative project that explores the potential of linked open data to make cultural heritage collections more accessible and interconnected. Led by ArkDes in partnership with Nationalmuseum, Tekniska museet, the Swedish National Heritage Board’s archive, and Wikimedia Sverige, the project focuses on linking archival and museum data through geographical metadata. This presentation will highlight key findings, methodologies, and the project's long-term impact on the GLAM sector. By empowering professionals to integrate Wikidata and other Wikimedia platforms into their workflows, the initiative fosters inclusivity, enhances research opportunities, and ensures the sustainability of open knowledge practices. Attendees will gain insights into how linked open data can bridge institutional silos, support cross-collection analysis, and create new pathways for engaging with cultural heritage materials in an open and meaningful way.
