Aligning the eARK4All Archival Information Package and Oxford Common File Layout Specifications
Neil Jefferies (Bodleian Libraries University of Oxford), Karin Bredenberg (Swedish National Archives)
The E-ARK4ALL project released an alpha version of its Common Specification for Information Packages (CSIP) for review at the end of November 2018. Slightly earlier, the Oxford Common File Layout (OCFL) initiative had also released an alpha version of its software independent preservation file organisation specification. While, at first sight, these would appear to attempt to do similar things, they are in fact, largely complementary approaches. While the eARK specification aims to define the logical structure and content of Open Archival Information Systems (OAIS) Information Packages, the OCFL describes how to map any logical digital object layout onto a physical file system in a preservation-friendly manner, as well as identifying the fundamental operations required to manage such objects. This paper provides a brief introduction to the two specifications and then describes how the OCFL can be applied to an E-ARK AIP.
A Perspective from Digital Preservation on Sustainability of E-Infrastructures
Simon Lambert (UKRI-STFC)
Much effort is expended on assuring sustainability of e-infrastructures and the services within them. Some of these services have a dimension of long-term preservation, in particular the infrastructure around persistent identifiers (PIDs). It is therefore worth asking whether established approaches to long-term digital preservation can offer insights into planning for sustainability. This paper examines some aspects of the OAIS Reference Model and their applicability to sustainability planning for e-infrastructures.
