Abstract
RDF 1.2 introduces triple terms and the rdf:reifies property as a native mechanism for statement-level metadata. However, declarative mapping languages such as RML, which generate RDF from heterogeneous data sources, have not yet been aligned with this update: prior RDF-star extensions predate RDF 1.2’s abstract data model and, furthermore, do not support its new directional language-tagged strings. This paper introduces RML 1.2, a backward-compatible extension of RML-Core for generating triple terms and directional language-tagged strings. We accompany the extension of RML with an open-source Python implementation and a suite of test cases.
