Overview
The MaschinenBauIndustrie (MBI) Knowledge Graph contains structured data from the book "Die Maschinen-Industrie im Deutschen Reich" written by Herbert Patschan in 1937. The book was scanned, OCR-ed, structured and semantified at UB Mannheim. The data includes basic data for the German companies from machine industry.
Access to data
- The MBI data is accessible by both humans and machines
- The MBI data is currently not available openly
- 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 Daimler-Benz A.-G.: https://mbi.kgi.uni-mannheim.de/entity/Q707.json, https://mbi.kgi.uni-mannheim.de/entity/Q707.rdf, https://mbi.kgi.uni-mannheim.de/entity/Q707.ttl, https://mbi.kgi.uni-mannheim.de/entity/Q707.nt and https://mbi.kgi.uni-mannheim.de/entity/Q707.jsonld.
Data model
- Properties
- Properties with capitalized labels are initial properties having datatypes "string" and used to model raw extracted data.
- Properties with non-capitalized labels are properties having various datatypes (e.g., "item", "time") and used to model "semantified data".
- Items
Use Cases
- Searching basic data for German companies in machine industry for the year 1937
- Matching your (meta)data to MBI data using the MBI reconciliation service
- Clean your tabular data and match it to the MBI knowledge graph with OpenRefine and the MBI reconciliation service
- Semantic annotation of tabular data using the MBI knowledge graph with bbw
- Federated queries over MBI, 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 MBI-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 MBI KG" as a subject.
- If you are new to knowledge graphs, check out materials at Wikibase Knowledge Graphs.
- The MBI knowledge graph is based on Wikibase, the software behind Wikidata. Therefore the Wikidata tutorials are also highly recommended.
