Sustainable Semantics for Sustainable Research Data

Abstract In view of the steadily growing volume of digital output from Humanities research projects in recent decades, the question of the long-term and sustainable preservation of this research data is becoming increasingly urgent. To meet this challenge, we are establishing the Central Knowledge Graph (CKG) as a key element of our documentation and publication strategy for research data. In this paper, we present two of the cornerstones of this strategy: The newly developed Project Description Layer Model (PDLM) provides the means to document the required contextual metadata about research projects and their digital outputs; the Zellij Semantic Documentation Protocol systematically documents the modeling patterns used to create CIDOC CRM representations of project data in a transparent and reusable way.
