The Mapping Manuscript Migrations (MMM) project transformed three separate datasets into a unified knowledge graph. The source databases include - Schoenberg Database of Manuscripts from the Schoenberg Institute for Manuscript Studies, - Bibale database from the Institute for Research and History of Texts, and - Medieval Manuscripts in Oxford Libraries. The Knowledge Graph has been created using the MMM data transformation pipeline. This dataset is available on a public SPARQL endpoint (<em>http://ldf.fi/mmm/sparql</em>) and it can be directly deployed onto a SPARQL endpoint using this docker recipe. To test and demonstrate its usefulness, the MMM Knowledge Graph is in use in the MMM Semantic Portal.
