A pragmatic application of PREMIS

Jack O'Sullivan (Preservica Ltd)

A data model is an expression of how a system is intended to be used, and a statement of how it should interact with other systems. As part of the development of the latest version of Preservica, the underlying data model was significantly altered, informed by what went before and by reference to the experiences and best practices distilled into the PREMIS Data Dictionary. This paper reports on some of the key decisions made in the application of the PREMIS concepts to an extant digital preservation system.

Getting Data out of Wikidata

Katherine Thornton (Yale University) and Kenneth Seals-Nutt (Yale University)

The Wikidata knowledge base provides a public infrastructure for creating and syndicating machine-readable data about computing resources. We have prepared a set of queries that can be used to gather data sets relevant to digital preservation from Wikidata. We present these data sets in the context of the Wikidata for Digital Preservation portal (Wikidp). Wikidp is a free software portal that allows people to explore data related to digital preservation from the Wikidata knowledge base. Structured data about file formats, the many versions of software titles, and computing environments, are already available in Wikidata. The content of Wikidata is licensed under the Creative Commons Zero (CC0) license, meaning that anyone can reuse the data for any purpose. The content in Wikidata is available in more than 300 human languages. The data in Wikidata is FAIR data, and it is linked open data. Our portal provides an interface designed for the needs of the digital preservation community.

The Matterhorn RDF Data Model: Formalizing Archival Metadata With SHACL

Tobias Wildi (docuteam GmbH) and Alain Dubois (Archives de l'Etat du Valais)

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.
