The Wikibase Ecosystem in DH and GLAM

DARIAH-EU Working Group DHwiki presents this White Paper about Wikibase and the Wikibase Ecosystem as a digest of its permanent activity in providing documentation about MediaWiki-based software solutions to researchers. The output of the Working group is accessible on its Wikibase instance at https://dhwiki.wikibase.cloud. As diverse as the Working Group itself is the target group of this report: DH researchers, GLAM institutions, contributors to the software platforms provided by Wikimedia, and software developers. When starting to engage with Wikidata and Wikibase, we have seen ourselves sometimes lost in a diverse landscape of disperse documentation resources with different scope and aimed at differently skilled readers. With this contribution, we hope to provide a comfortable pathway towards adopting Wikibase in FAIR Linked Data publishing and collaborative data curation workflows. To help users navigate these platforms, this article brings together the main elements of the Wikibase ecosystem with a specific focus on DH and GLAM usecases. It explains the main structure and features of Wikibase, discusses key processes such as data round-tripping and reconciliation, and examines the role of Wikidata and Wikibase in managing identifiers, authority data and controlled vocabularies. By bringing these aspects together, the paper aims to supportthe use of Wikibase in FAIR-compliant and collaborative data workflows, while also drawing attention to wider issues such as sustainability, governance andreuse.
