Matterhorn RDF is a linked data-based model for archival metadata with the goal of improving the contextualization of archival records. It covers the three standards ISAD(G), ISAAR(CPF) and ISDF, as well as the areas “Preservation Description Information” and “Representation Information” of the OAIS information model. For the implementation of Matterhorn RDF, classes and properties of existing ontologies are used. The formalization of the model is realized with the help of SHACL shapes.
