preservation / curation Logo Research cannot flourish if data are - PowerPoint PPT Presentation

preservation / curation Logo • „Research cannot flourish if data are not preserved and made accessible. All concerned must act accordingly.“ Nature 461, 145 (10 September 2009), doi:10.1038/461145a 1

Photon Sciences + X ‐ ray Facilities Logo • motivation: costs of data creation 2.000€/h beamline + overhead 120k€ ‐ 50M€ (ribosome ‐ structure) • data preservation and re ‐ use (status) portable USB hard ‐ disks, responsibility of researcher • data preservation and re ‐ use (goal) sharing, re ‐ use and integration, validation of results • requirements federated repositories open access (after a 5 year moving wall) Web ‐ based (Shibboleth) but integrated in Grid

German Language Studies Logo • preserve, share, analyze, re ‐ use German literature texts • 1,5 Mio texts + metadata + annotations = 5TB • requirements – versioning – provenance – licensing + IPR (author, publisher) → data are irretrievable, but may need to be deleted http://www.nlcphs.org/Academics/English/Pictures/shakespeare.jpg

variation in community requirements Logo • existing infrastructure available not available (climate) (bio statistics, social sciences, archaeology) • data types homogeneous heterogeneous (literature) (medicine) • data integrity erasable phases, versioning not changeable (literature) (humanities) (climate) • rights – open access: climate – licensing: literature – de ‐ personalization: medicine – private data: photon sciences 4

curation layers Logo research digital object data research data/ conceptual object semantics formats, logical object e.g. images, XML bit-stream physical object cf. Thibodeau: Overview of Technological Approaches to Digital Preservation and Challenges in Coming Years, 2002. http://www.clir.org/pubs/reports/pub107/thibodeau.html 5

finally Logo • there is no single approach that serves all needs (curation) • foster interoperability to emerge locally (not force) • link activities / communities 11
