Abstract
The W3C Generating RDF from Tabular Data on the Web Recommendation provides a mechanism for mapping CSV-formatted data to any RDF graph model. Since the Wikibase data model used by Wikidata can be expressed as RDF, this Recommendation can be used to document tabular snapshots of parts of the Wikidata knowledge graph in a simple form that is easy for humans and applications to read. Those snapshots can be used to document how subgraphs of Wikidata have changed over time and can be compared with the current state of Wikidata using its Query Service to detect vandalism and value added through community contributions.

Baskauf / Using CSVs to manage small Wikidata datasets files. Because those data are exposed as RDF through the Wikidata Query Service,2 Wikidata provides an entrance to the Linked Open Data (LOD) cloud3 with a relatively low barrier to entry
We describe a method for mapping specific Wikidata properties and the Wikibase model generally to flat CSV files using the Generating RDF from Tabular Data on the Web (CSV2RDF) W3C Recommendation, making it possible for humans to interact more with the data locally using spreadsheet software
Summary
O Because of its availability and ease of use, Wikidata has become one of the widely used open knowledge graphs C [21]. Its dedicated users and easy-to-use graphical interface promise value added through community contributions, and access through its API1 makes it possible for large amounts of data to be contributed via bot scripts [29] that upload data from a variety of sources These advantages have generated a lot of interest among biodiversity informaticians [20], information specialists [15], and others in communities such as galleries, libraries, archives and museums (GLAM) [30], for using Wikidata as a place to expose and manage data about items of their concern, such as collections records, authors, and authority. We describe a method for mapping specific Wikidata properties and the Wikibase model generally to flat CSV files using the Generating RDF from Tabular Data on the Web (CSV2RDF) W3C Recommendation (i.e. standard), making it possible for humans to interact more with the data locally using spreadsheet software.
