Practices of Linked Open Data in Archaeology and Their Realisation in Wikidata

In this paper, we introduce Linked Open Data (LOD) in the archaeological domain as a means to connect dispersed data sources and enable cross-querying. The technology behind the design principles and how LOD can be created and published is described to enable less-familiar researchers to understand the presented benefits and drawbacks of LOD. Wikidata is introduced as an open knowledge hub for the creation and dissemination of LOD. Different actors within archaeology have implemented LOD, and we present which challenges have been and are being addressed. A selection of projects showcases how Wikidata is being used by archaeologists to enrich and open their databases to the general public. With this paper, we aim to encourage the creation and re-use of LOD in archaeology, as we believe it offers an improvement on current data publishing practices.
