A nanopass approach to a modular RDF implementation

Abstract

Resource Description Framework (RDF) is a widespread W3C standard defining a domain-specific language for knowledge representation, providing a platform to build higher-level languages such as OWL or SHACL. RDF concrete syntaxes define an external representation of its abstract model for data interchange. Despite sharing the same core semantics, RDF concrete syntaxes differ in how well they support common modelling idioms at the surface level. Many RDF libraries have been implemented in Scheme, however, they support few concrete syntaxes and/or do not exhibit compliance with the W3C test suites.
