This is a suite of scripts and models that refactor the metadata set of the Project Gutenberg digital library, with the aim of turning it into a proper Linked Data set.

• Reconciliation of blank nodes, resulting in a much smaller dataset (~29% smaller as of March 2020)
• Linking with Library of Congress subject headings and classification systems
• Structuring of Table Of Contents data
• Ontology alignment of undocumented Gutenberg terms

You need:

• Python 3
• an RDF store with SPARQL querying/updating over HTTP (e.g. Jena Fuseki, Virtuoso, BlazeGraph)
• The Project Gutenberg catalog as RDF - Download at https://www.gutenberg.org/wiki/Gutenberg:Feeds

1. Download the metadata set from Gutenberg and load it onto your RDF store.
2. cd gutenberg-fixes
3. In settings.py set the SPARQL service and RDF graph name
4. python refactor.py bookshelves formats toc (or a subset of the three arguments)
5. in gutenberg-fixes/queries you can find other SPARQL queries to run by yourselves.
