Research Objects Preservation

In this talk, presented at the Digital Preservation 2014 meeting, we discuss practical and conceptual considerations of capturing and preserving the lifecycle of research products. We employ the concept of complex research object (RO). Building upon our experience with SEAD, a suite of services designed to support active curation and long-term preservation of sustainability science data, we extend the research object model in order to develop a system that supports transformations from active data (live objects) into published data (publication objects) and further into versioned objects that contain changes or support new research.

Research Objects Preservation

  1. 1. Inna Kouper, Beth Plale, Dharma Akmon, Margaret Hedstrom Practical and Conceptual Considerations of Research Object Preservation Digital Preservation 2014 Meeting Washington, DC July 23, 2014
  2. 2. Data Preservation Challenges • Research spans over months or years • Data are heterogeneous and complex • Data changes states through collection, processing, analysis and publication • Processes are as important as products • Multiple agents, including individuals and organizations, are involved • People, processes and products are in non-linear relationships Capture and formalize for automation, reproducility and re-use?
  3. 3. Research Object Unique ID Agents StatesRelationships Content Research Object Framework • Data creator • Curator • Data re-use scientist • Live • Curated • Published • Aggregates • Related to • Describes • Derived from • Versioned from • Files • Bitstreams • Pointers Bundles of resources that use common standards and services to transfer and consume them
  4. 4. Live Objects • In a state of flux • Handled by members of the project team • Transition initiated by intent to publish Curation Objects • Content packaged using BagIT protocol • Metadata and relationships captured via OAI/ORE maps • Mutable, but changes are selective (metadata) Publication Objects • Immutable and citable (DOI) • Deposited using the best match algorithm • Lineage (revisions and derivations) is tracked Research Object States
  5. 5. Working with Live Objects
  6. 6. Curation and Publishing
  7. 7. Broader Implications • RO concept and its implementation in SEAD allows us to document content, context, processes, states • Entities can be edited on multiple levels • ROs can be deposited to institutional repositories, cloud storage, domain repositories • Needed: – multiple licensing and permissions (to address diverse models of RO ownership) – sophisticated lineage tracking (to build trust, authority and authenticity) – cases of re-use (to create better tools and services)
