share in the sum of all knowledge. That's our commitment.

4. Wikidata + Heritage Data:
A Short Introduction

5. • Establish Wikidata as a database that covers the entire world’s cultural
heritage.
• Establish Wikidata as a central hub that interlinks GLAM collections
around the world; and provides links to bibliographic, genealogic,
scientifc and other collections of information; create the ultimate
authority file.
• Foster truly multilingual and global collaboration among people from
various backgrounds.
• Leverage synergies between institutions, reduce duplicate work.
• Encourage debate in the community by highlighting and interrogating
differences in perspective.
• Provide a single source of data for some of the most popular web
sites and apps, including Wikipedia infoboxes and lists.
Vision (Blog posts: Stinson et al. 2016; Thornton / Cochrane 2016; Poulter 2017)

6. Thematic Projects
https://www.wikidata.org/wiki/Wikidata:WikiProject_Cultural_heritage [Example]

7. Wikidata + Performing Arts

8. • Realize an international performing arts database on the
basis of Wikidata
• Provide a powerful finding aid for performing arts related content
on Wikimedia Commons and elsewhere
• Promote Wikidata-powered performing arts related information
on various information platforms, including Wikipedia
• Get heritage institutions to make their performing arts related
data and content available through Wikidata, Wikimedia
Commons & other inter-connected platforms.
Vision: International Database for the Performing Arts
Role Model Projects for Inspiration:
• MusicBrainz (music recordings)
• IMDb (movies)
• IMSLP (music scores)
• Operabase (opera)

9. In the area of theatre in general:
• Pilot ingest Repertoire of Schauspielhaus Zürich 1938-1968
(~700 productions)
• Data ingest Flanders Arts Institute (over 12000 productions)
In the area of opera:
• Working toward pilot ingests of:
• Carnegie Hall Performance History (opera-related performances)
• Catalog of the Ehrenreich Collection
• Ingest of operas, arias, roles
Outlook:
• Further ingests in the pipeline
• Start resolving data modelling issues
• Start resolving data quality issues (references, inconsistencies, etc.)
• Encourage the creation of first pilot applications
State of Implementation – Focus on Wikidata

14. • There is plenty of relevant material, but it needs organizing and curation
• Structured data on Wikimedia Commons is expected to be a great enabler
Status Quo – Wikimedia Commons

15. Synergies & Potential for Cross-pollination

16. Wikidata, Wikipedia, Wikimedia
Commons
• Complementary data (artists, works,
etc.)
• Potential for crowdsourcing / community-
sourcing certain aspects of data
maintenance
• Application of the data model in an
international context
• Visibility, exposure of performing arts
related information
Swiss Performing Arts Platform
• Plenty of performance data from
Switzerland
• Comprehensive data model for the
performing arts domain
• Plenty of know-how and source material
in the area of the performing arts
• Digital content (in the longer term, due to
copyright issues)
Areas for Cooperation
• Mutual interlinking of data & content
• Community building and outreach to further data providers
• Establishing a widely accepted data modelling practice in the area of the performing arts
• Organization of editathons and similar events
