The Oxford Common File Layout (OCFL, specification describes an open and application-independent approach to the storage of digital objects in a structured, transparent, and predictable manner. It is designed to promote sustainable long-term access and management of content within digital repositories.

Repository content — that is, the digital files and metadata that a repository might manage — is typically much more durable than the repository software application. By providing a specification for file layout, the OCFL is an attempt at reducing, or even eliminating, the need for time consuming and risky data migrations associated with software transitions. The resulting structure supports deployment and replication using filesystems and object store technologies, and provides a basis for shared tooling. The OCFL specification builds on experience with the BagIt specification and the Moab design to support strong fixity checks and to provide a simple structure to efficiently capture versions of object contents so that all previous states of an object may be recovered and examined.

This presentation will focus on the motivations and vision for the OCFL, explain key choices in the specification, and describe the status of implementation efforts.


Implementation of a Research Data Repository using the Oxford Common File Layout standard at the University of Technology Sydney

Michael Lynch, Peter Sefton

University of Technology Sydney, Australia

This presentation will discuss an implementation of the Oxford Common File Layout (OCFL) in an institutional research data repository at the University of Technology. We will describe our system in terms of the conference themes of Open and Sustainable and with reference to the needs and user experience of data depositors and users (many have large data, and or large numbers of files). OCFL, which is an approach to repository implementation based on static data was developed to deal with a number of issues with “traditional” repository design, many of which are particularly acute when dealing with research data, we will cover how this meets our user and institutional needs and is a sustainable approach to managing data.

Preserving and sharing are core reproducible practices that require substantial efforts in preparing and documenting research data analyses. Dedicated tools and services are developed to support researchers in this process. However, lowering preservation barriers to partial data preservation might not only lead to insufficient data reuse in the future; we argue that it might prove insufficient to convince researchers to follow reproducible practices at large. Instead, we need a better understanding of incentive structures that research repositories can support and implement. In this presentation, we report on our researcher-centered studies in the context of a research preservation prototype service tailored to High Energy Physics experiments. Our studies show that an in-depth understanding of research practices allows to characterize technology’s secondary usage forms. If reflected in design, they can provide contributing scientists with meaningful benefits regarding automation, uncertainty coping, communication and collaboration. We further reflect on our research regarding the use of motivational and persuasive design and highlight the potential that researchers see in adopting such design tools. It will be interesting to compare the results of this study with research data preservation incentives in other scientific disciplines.
