    Curation of Research Data Curation of Research Data Presentation Transcript

    • UKOLN is supported by: The curation of research data Michael Day Research and Development Team Leader UKOLN, University of Bath MSc Lecture, UWE, Bristol, 10 March 2010
    • Presentation outline
      • Why curate research data
      • Repositories and the curation of research data
        • Roles and responsibilities
        • Infrastructures
        • Curation challenges
    • Dealing with research data
      • An extremely broad category of material:
        • “... any information that can be stored in digital form, including text, numbers, images, video or movies, audio, software, algorithms, equations, animations, models, simulations, etc.” (National Science Board, Long-lived digital data collections, 2005)
        • In practice, it can mean almost anything
    • Why curate research data? (1)
      • Part of the normal research process:
        • The need for others to validate and replicate research
        • In some disciplines, supporting data is routinely made available to reviewers and linked from journal papers
        • Principles of sharing and openness are firmly embedded in some disciplines
    • Why curate research data? (2)
      • Extrinsic and intrinsic value;
        • High investment in research
        • Data can be very expensive to capture and analyse
        • Data is impossible to recreate once lost
        • Observational data (by definition) is irreplaceable
        • Current generations of instruments can gather more data than can be analysed
    • Why curate research data? (3)
      • The potential for creating 'new' knowledge from existing data:
        • Re-use, re-analysis, data mining
        • Annotation, e.g. in molecular biology astronomy
        • Combining datasets in innovative ways, e.g. mapping biodiversity data onto ecological GIS
        • “Science 2.0” – Open Science
    • Why curate research data? (4)
      • It is increasingly a requirement of some research funding bodies
        • Some have quite mature data retention policies (not necessarily for permanent retention)
        • Increasing expectation of access to data from publicly-funded research
        • OECD Principles and guidelines for access to research data from public funding (2007)
    • Why curate research data? (5)
      • Institutional asset management:
        • Universities and other research organisations invest very large sums of money into research activities
        • Research data is a key output of this activity
        • It is, therefore, an institutional asset that needs stewardship
    • Why curate research data? (6)
      • Promoting the institution, research group or individual:
        • Re-use helps promote visibility and 'impact'
        • Institutions become acknowledged 'centres of competence'
    • Who undertakes preservation?
      • Researchers
        • Indirectly - they have most direct contact with creation stage, and understand how data can be used
        • Directly - sometimes responsible for maintaining community data collections
      • Information professionals
        • Sometimes, but it depends on the context
      • IT professionals
        • Primarily informaticians working with scientists
    • Roles and responsibilities (1)
      • Long-lived data collections (NSB)
        • Data authors
        • Data managers
        • Data scientists
        • Data users
        • Funding agencies
      • Dealing with data (JISC)
        • Scientist
        • Institution
        • Data centre
        • User
        • Funder
        • Publisher
    • Roles and responsibilities (2)
      • Scientists
        • Initial creation and use of data
        • Expectation of first use and in gaining appropriate credit and recognition
        • Responsible for:
          • Managing data for life of project
          • For using standards (where possible)
          • For complying with data policies
          • For making the data available in a form that can (easily?) be used by others
    • Roles and responsibilities (3)
      • Institutions:
        • Role less clear
        • Institutional policies may require short-term management of data
          • Advocacy and training
        • Some institutions are developing repository services
          • Are rarely currently used for research data
          • Federated approaches maintain disciplinary involvement
    • Roles and responsibilities (3)
      • Data centres
        • Undertakes curation and provides access
        • Responsible for:
          • Selection and ingest
          • Participating in the development of standards
          • Protecting the rights of data creators
          • Supporting ingest and metadata capture
          • Supporting re-use (tools and services)
          • Training
    • Roles and responsibilities (4)
      • Users:
        • Users of third-party data
        • Responsible for:
          • Adhering to any licenses and restrictions on use
          • Acknowledging data creators and curators
          • Managing any derived data
          • Provide feedback to scientists and data centres
    • Roles and responsibilities (5)
      • Funding bodies:
        • Acting at policy level
        • Responsible for:
          • Considering wider policy perspectives
          • Developing policies in co-operation with other stakeholders
          • Monitoring and enforcing data policies
          • Support for long-term data management
          • Support for data curation
    • Research data collections (1)
      • A typology (1):
        • From National Science Board report Long-lived digital data collections (2005)
          • Research data collections – the products of one or more focused research projects
          • Resource or community data collections – collections that emerge to serve particular subject sub-disciplines
          • Reference data collections – serve a broader and more diverse set of user communities
    • Research data collections (2)
      • Data in “research data collections” is most at risk
        • A modern version of the “file-drawer problem”
        • Data stored on personal hard-drives or on media; largely undocumented
        • Particular challenge when the data creator has retired or moved to another institution
        • Data creators not always aware of its potential value
        • The reward structure of science is not always helpful
    • Curation infrastructures (1)
      • Focus on the generic:
        • Need for a balance between:
          • The 'bottom-up' discipline-based drivers that promote the generation of research data
          • The policy level, looking to make cost effective investment in curation
        • When building Infrastructures, focus on the generic
          • Storage systems and middleware
          • Preservation services
          • Identifying the needs of the wider community
    • Curation infrastructures (2)
      • The need for collaboration:
        • Need for 'deep-infrastructure' recognised as far back as 1996 by the Task Force on Archiving of Digital Information
        • Digital preservation involves the "grander problem of organizing ourselves over time and as a society ... [to manoeuvre] effectively in a digital landscape" (p. 7)
    • Curation challenges: Costs
      • NSF Task Force looking at this subject:
        • Sustainable Economics for a Digital Planet (2010): http://brtf.sdsc.edu/
      • JISC-funded LIFE (Life Cycle Information for E-Literature) project is developing a predictive costing tool
        • http://www.life.ac.uk/
      • JISC-funded study ( Keeping research data safe , 2008) focused on research data curation at the institution level
        • The complex service requirements for curating research data means that institutions are setting-up federated approaches to repository development
        • Currently ingest costs are much higher than long-term storage and preservation costs
    • Curation challenges: Scale (1)
      • The “digital deluge” in e-Science
        • New generations of instruments
        • Computer simulations
        • Many terabytes generated per day, petabyte scale computing (and growing)
        • Cory Doctorow, “Welcome to the petacentre.” Nature, 455, pp 17-21, 4 Sep 2008
        • Are Institutional Repositories ready for this?
      • Digitised content:
        • Google Book Search (~10 million items)
        • A role for research libraries?
    • Curation challenges: Scale (2)
      • Problems of scale are particularly acute in traditional 'big-science' disciplines:
        • Particle physics (e.g., the Large Hadron Collider)
        • Astronomy (sky surveys, etc)
      • But “smaller experiments will grow the fastest” (Szalay & Gray, Nature , 440, 413-4, 23 Mar 2006)
        • Bioinformatics, crystallography, engineering design, and many others
      • In some cases it may be cheaper just to generate the data again, e.g. for computer simulations
    • Curation challenges: Complexity (2)
      • Research data is extremely diverse - not really a single category of material
        • tabular data, images, GIS, etc.
        • raw machine output vs, derived data
        • varying levels of structure (XML, legacy formats, etc.)
        • many different standards
      • Research data is not homogeneous
      • No one-size-fits-all approach possible
    • Curation challenges: Cultures
      • Diverse research cultures
        • Data practices vary widely, even within a single discipline
          • Gene sequence data is typically deposited in public databases
          • In proteomics, sharing is not so widespread; partly driven by lack of standards, but there is also concern about who have exploitation rights
        • Role of commercial interests
          • Pharmaceuticals, architecture and engineering, geological prospecting
    • The Future ...
      • “It is always a mistake for a historian to try and predict the future. Life, unlike science, is simply too full of surprises” - Richard J. Evans, In defence of history (1997, p. 62)
