English: This paper is part of the project ‘Linked Open Data publication with Wikidata’. This is the fourth project deliverable (D4. Manual Open Data management in Wikidata) and was described in the project plan as follows:

'Based on the whitepaper, the experiences from the first Workshop and the upload of data in Wikidata, a manual will be created for data publishers who aim at publishing collection information on Wikidata.'

The manual is first and foremost interesting to collection managers, but is also of interest to volunteers who add and adapt information about art on Wikidata.

The manual consists of four chapters (and a couple of Annexes). First we indicate how you can manage existing data on Wikidata (looking for data, change it, add references, …). In a following chapter you learn how you can add new items to Wikidata, both manually as with the help of a bot (volunteer). We also look at how data can be used and how changes (to the data) can be monitored. Finally you read more about the available export(s) of Wikidata information, and we showcase some examples of data applications.

The manual also contains a small appendix, listing some handy tools that you can use inside Wikidata, an overview of the mapping of object type terms as used by the museums - with the terms used in Wikidata; information on notability and a couple examples of SPARQL-queries.
