Overview
The "Wer Leitet" (WL) Knowledge Graph is free and open. It contains data about people who lead various companies in Germany from 1940 to 1941.
Access to data
- The WL data is accessible by both humans and machines
- List of properties
- List of items
- Advanced search for items
- SPARQL endpoint
- API
- Export to CSV
- Every entity can be downloaded in .json, .rdf, .ttl, .nt and .jsonld formats. An example for Hermann J. Abs: https://wl.kgi.uni-mannheim.de/entity/Q20.json, https://wl.kgi.uni-mannheim.de/entity/Q20.rdf, https://wl.kgi.uni-mannheim.de/entity/Q20.ttl, https://wl.kgi.uni-mannheim.de/entity/Q20.nt and https://wl.kgi.uni-mannheim.de/entity/Q20.jsonld.
Use Cases
- Searching identifiers of German companies for the period 1940-1941
- Matching your (meta)data to WL data using the WL reconciliation service
- Clean your tabular data and match it to the WL knowledge graph with OpenRefine and the WL reconciliation service
- Semantic annotation of tabular data using the WL knowledge graph with bbw
- Federated queries over AWL, Wikidata and other SPARQL endpoints
Get involved
- You can contribute to this project in various ways: matching data, data quality checks and data editing/upload.
- You can give your feedback at GitHub WL-KG Issues.
- You can get an account here via email request to the Research Data Center at UB Mannheim. Please write "Request an account at the WL KG" as a subject.
- If you are new to knowledge graphs, check out materials at Wikibase Knowledge Graphs.
- The WL knowledge graph is based on Wikibase, the software behind Wikidata. Therefore the Wikidata tutorials are also highly recommended.
