About this project

This site presents a prototype pipeline for publishing art exhibition data as Linked Open Data (LOD). It was created with students of the Bachelor of Arts Information Management at Hochschule Hannover in the course BIM-126-02 Data Science (SoSe 2026).

Goal: Retrieve exhibition catalogue records from the Deutsche Nationalbibliothek (DNB), structure them using an open data model, upload them to a Wikibase knowledge base, and publish the results as a Quarto website — all reproducibly and with full documentation.

The pipeline

DNB SRU API → MARC21-XML → CSV → Wikibase → SPARQL → Quarto website
Step Notebook Output
1. Retrieve DNB records 01_dnb_search.ipynb sprengel_raw.xml
2. Filter & extract fields 02_dnb_filter_exhibitions.ipynb sprengel_exhibitions.csv
3. Fetch cover images 03_dnb_cover_images.ipynb images/*.jpg
4. Upload data model 04_wikibase_data_model.ipynb Wikibase properties
5. Upload exhibitions 05_wikibase_upload.ipynb Wikibase items
6. Upload images 06_mediawiki_upload.ipynb MediaWiki files
7. Test SPARQL 00_sparql_health_check.ipynb SPARQL test
8. Test bot 00_wikibase_bot_test.ipynb bot test
