AbstractDigital repositories are particularly susceptible to the problem of uncontrolled data and metadata instantiation because of the complex lifecycles of data deposit, use, and reuse. In repositories that require deposit of research data on a large scale, instantiation can become particularly acute. DANS (Data Archiving and Networked Services), a division of the Royal Netherlands Academy of the Arts and Sciences, is the self-styled “institute for permanent access to digital research resources” (DANS 2017). The role of DANS is to encourage scholars to make their data accessible, interoperable and resusable, in a sustainable environment. In addition to serving as a host repository for tens of thousands of datasets, DANS also manages the NARCIS gateway to more than 160,000 datasets generated by Dutch scholars. Recent research (Smiraglia and Park 2016) demonstrated one approach to a conceptual model of instantiation among open government data records, deriving core attributes “information object,” “expression,” “manifestation product type,” “actor, “expression creation,” and “information carrier” from the FRBRoo ontology of bibliographic instantiation. The proposed presentation combines these and other FRBRoo attributes with the generations of lifecycle modeling identified by Greenberg, as applied to a series of use cases from DANS.
