Mapping Manuscript Migrations: SPARQL Query

ldfmmm/sparql-select

Runs a read-only SPARQL SELECT query against the Mapping Manuscript Migrations knowledge graph (https://ldf.fi/mmm/), which links medieval and Renaissance manuscripts to their production and ownership events, people, places and collections, merged from the Bodleian Library, the Schoenberg Database and Bibale. You write the SPARQL, for example SELECT ?s ?label WHERE { ?s <http://www.w3.org/2000/01/rdf-schema#label> ?label } LIMIT 5. The answer is the standard SPARQL JSON result: `head.vars` and `results.bindings`, one object per solution with each variable as {type, value}. The query must end with LIMIT n (1 to 100), optionally followed by OFFSET m; page with OFFSET. SELECT only (PREFIX lines allowed before it), at most 2000 characters, no SERVICE clause. Aggregates over the whole graph can take 25 seconds or more. A query that matches nothing returns empty bindings. Use manuscript-search to find a manuscript by shelfmark text.
