Current Tasks

Getting access to and building an inventory of data sources

• List databases containing data about heritage institutions in the Data Sources section. In case the databases are not publicly accessible, contact the data holder in order to encourage them to release the data to the public (under a CC-0 Waiver or equivalent).

Preparation tasks in view of data ingestion

• Describe the databases listed on the Data Sources page on Wikidata, identify unique identifiers in the source data set and prepare their ingestion into Wikidata (see the Data Sources section for instructions).
• Map the data structure in the source data set to the data structure on Wikidata (see the Data Sources section for instructions).
• Make sure that the relevant thesauri needed for data ingestion, such as the typology of heritage institutions used as well as the municipalities and territorial subdivision of the given country exist on Wikidata; if not, complement them (see the Data Sources section for instructions).
• Clean up existing Wikidata items so that they conform to the data modeling guidelines laid out in the Data Structure section (instructions will follow - in the meanwhile, please refer to the case reports referenced here).

Data ingestion

• Ingest data from an existing database (instructions will follow - in the meanwhile, please refer to the case reports and guidelines referenced here).
• Tidy up data after batch ingestion from a database (tackle double entries, add “part of”, “has part” relationships, add information about “inception” and/or “dissolution” of institutions where required) (instructions will follow - in the meanwhile, please refer to the case reports and guidelines referenced here).
• Complement data that has already been ingested, e.g. by adding translations, urls, etc. (see the guidelines on how to edit Wikidata data in spreadsheet mode).

Development of the data model

• Help improving the ontologies and multilingual thesauri needed for the ingestion and proper representation of the data (see the Data Structure section and the Typology section for to do lists).

Wikidataification of infobox templates on Wikipedia

• Complement the infobox overview tables by adding information about missing language versions (see the Data Structure section for a to do list).
• If you are familiar with the creation of templates on Wikipedia: please spread the word about this project in the various Wikipedias and help modify the templates so that they directly fetch data from Wikidata (see the Data Structure section for a to do list).

Wikidataification of lists on Wikipedia

Instructions are missing; please provide them if you can. Start with maintenance lists on project pages, driving the creation of new articles.

Track data quality and completeness

Instructions are missing; please provide them if you can.

Tools

This section is still empty. If you want to help building it up, start listing relevant tools with a short explanation (possibly, a template on the level of WikiProject Cultural heritage should be created that can be included in various WikiProjects). See also the tools section of the case report about the ingestion of data about Swiss heritage institutions.

Maintenance lists

This section is intended for Wikidata maintenance lists, e.g. for the following-up on constraint violations, etc.

Feel free to create and add maintenance lists related to heritage institutions.
