Abstract
RDF is a graph data model, thus often the best way to understand RDF data schemas (ontologies, application profiles, RDF shapes) is with a diagram. We describe a tool (rdfpuml) that makes true diagrams from Turtle examples using PlantUML and GraphViz. Diagram readability is of prime concern, and rdfpuml introduces a few diagram control mechanisms using triples in the puml: namespace. We give examples from Getty CONA (Mappings of museum data to CIDOC CRM), Multisensor (NLP2RDF/NIF, FrameNet), EHRI (Holocaust Research into Jewish social networks), Duraspace (Portland Common Data Model for holding metadata in institutional repositories)
