Advanced Climate Research Infrastructure for Data

JISC 14/09• Citing: “Agreed conventions for data citation and for
data description are important for research data discovery. Persistent identification is required...”
• Linking: “A recent position paper written for JISC ... makes a case for the benefits of linking research data using semantic or linked data technology ... data on which a journal article is based are bi-directionally linked to other data, resources, articles and people.”
• Integrating: “Integrating heterogeneous data across distributed sources can enable effective and innovative reuse”
ACRID• Advanced Climate Research Infrastructure for Data• Collaboration between:
– Climatic Research Unit, University of East Anglia– STFC e-Science Centre, Rutherford Appleton Laboratory– Met Office (unfunded partner)
• Various inquiries following 2009 email hacking recommended greater access to data and workings
• Project aims:– Information architecture, tools, infrastructure for managing
climate data and processing workflows– ‘linked-data’ approach for climate data publishing and citation– Prototype using four high-profile climate datasets
Citing• Convergence around DOI for linking
publication to data in Earth science– DataCite, Parsons and Duerr (2010), Wilson et.
al. (2010), UNESCO (2010), ESSD, etc.
• But “(w)hat is the citeable unit within a DOI?”– file? set of files? OAIS AIP?
• Answer: linked-data graph
Linking
Integrating• An example information model for Observations
and Measurements (ISO/DIS 19156)– An observation is an event that estimates an
observed property of a feature of interest, using a procedure, and generating a result
