Estermann LODEPA & Wikidata 20191025

  1. 1. Linked Open Data Ecosystem for the Performing Arts: Which Place for Wikidata? Prof. Beat Estermann, Bern University of Applied Sciences Wikidata Conference, 25 October 2019 Photo: Phantom black light theatre (theatre group HILT), User:Black light theatre Prague, Wikimedia Commons, CC BY-SA 4.0.
  2. 2. Many reports – one call to action Over the past five years, the topic of performing arts metadata has emerged as one of the most pressing issues for the performing arts sector.
  3. 3. Production market The Vision: Many Stakeholders – One Knowledge Base Performing Arts Value Network International Knowledge Base for the Performing Arts Distributed Architecture Key Stakeholders Usage Scenarios
  4. 4. Performing Arts Value Network Production market Based on: Bonet, L., & Schargorodsky, H. (2018). “Theatre management: models and strategies for cultural venues”. Policy, 23(2), 159-173.
  5. 5. Stakeholder Requirements Regarding Data Coverage
  6. 6. Architecture of Platforms
  7. 7. Swiss Performing Arts Database Wikidata / Wikimedia Commons Culture Creates concerts State of Implementation
  8. 8. 1. Immediate focus should be placed on populating a Canadian performing arts graph. 2. Wikidata is complementary to Artsdata.ca; efforts should therefore be undertaken contribute to its population with performing arts related data. 3. A data governance framework needs to be developed in cooperation with representatives from across the arts sector to establish who is able to share what data with whom, and who will have authority over which data/information. 4. Further research is needed to better understand user requirements with regard to adoption of linked open data practices in existing and emerging service offerings. 5. Further effort is required to develop and describe novel business models that and maintain a well-functioning linked open data ecosystem for the performing Recommendations by the LDFI Advisory Committee
  9. 9. Wikidata and classical LOD are complementary Wikidata Classical LOD Strengths Fully-fledged crowdsourcing platform; further parties can easily be invited to contribute. Data owners keep the control over their «graphs»; data quality and completeness remains under the control of the data provider. Immediate integration with the worldwide linked data cloud (reconciliation at the moment of data ingest) Data can be published in RDF format, is linkable; reconcilation against other databases can be done step by step. Community-supported LOD service with a certain level of reliability Weaknesses Monitoring data quality and completeness is a permanent and challenging task. Third parties cannot readily fix issues related to data quality or completeness that are not taken care of by the data provider. Harmonization of data modelling practices is a challenge. Harmonization of data modelling practices within one’s own «silo» is straightforward, but might be a great challenge to implement across «silos». Perceived «loss of control» by data owners Introducing collaborative data maintenance practices is difficult. Many current LOD services are of questionable reliability.
  10. 10. Wikidata in the wider context of the Linked Open Data Ecosystem for the Performing Arts When it comes to publishing data on Wikidata, priority should be given to data: • where it is unclear who would be the «natural» authority in the given area (on a global scale); • where there is a high potential for enhancing data through crowdsourcing approaches (including community or expert sourcing); • where data is likely to be reused in the context of Wikipedia; • where international coordination to ensure semantic interoperability of the data is unlikely to take place elsewhere. Focus on base registers / authority files and controlled vocabularies first; they facilitate further interlinking of datasets!
  11. 11. From «Sum of All GLAMs» to «Wiki Loves Performing Arts» Sum of All GLAMs Project
  12. 12. COST Action: Linked Open Data Ecosystem for the Performing Arts (LODEPA) Topics to be covered • Coordination of data modelling & ontology development (including controlled vocabularies) • Base registers, authority data • Federation (Wikidata, classical LOD approaches) • Implementation of international campaigns to supplement data on Wikidata • Sharing of infrastructure components • Exchange of best practices regarding governance, skills development and organizational capacity building • Development of business models, international exchange/transfer of services • further topics to be collected through interviews with key stakeholders
