• Basic curation – tape migration to new media very 3 years; (Cost driven), and routine check-summing;

• No current plans for longer term curation ?– A good time to start making plans

• The data is the easy bit; we’re just the data centre

Data management for facilities at RAL site

• ISIS (neutron source) – All data ever - 30 years

• Diamond Light Source– 2 years operation 20+ beam lines – Automated data handling facility and metadata capture– Upgrading infrastructure from SRB to Storage-D/IRODS

• Central Laser Facility• Space science Centre

Other related DP activities• Data preservation for Medical Research Council

(Policies)• Data archive for Biotechnology and Biological

Sciences Research Council (10 years)• Data archive for Natural Environment Research

Council• Investigating Commercial product from Tesella

(“Safety Deposit Box” – Pronom)• Site wide panel (still) developing “Data Policy”

Specific goals for Research Datasets Testbed (SCAPE)

• Create sample shareable datasets from large scientific facilities such as neutron sources and synchrotron radiation sources, with associated instruments, serving wide scientific communities.

• Develop preservation scenarios for typical preservation processes which represent the diversity the scientific research lifecycle

• Identify requirements for the tools and services (and underlying infrastructure) that are required in order to meet the challenges of this domain

• Implement the research data scenarioso in the SCAPE environment in order to test, evaluate, demonstrate and ensure the practicality and applicability of the SCAPE developments to this problem area

OAIS update – clarifications and improvements (David Giaretta)

• Audit & Certification built on top of OAIS concepts and ISO audit processes• - leads to cycle of continuous improvement• - audit and certification organisation being created• - European Audit Framework being set up

• PARSE.Insight provided huge survey responses to understand what people are concerned about and the major threats to digital holdings

• CASPAR provided tools and infrastructure components (i.e. Usable across disciplines). Validated through accelerated lifetime tests, changing hardware, software, environment and tacit knowledge of users. Used data from various science disciplines (STFC and ESA), cultural heritage (UNESCO) and contemporary performing arts (IRCAM, INA, CIANT, UnivLeeds)

• VISION to 2030 from EU High Level Expert Group on Science Data Infrastructure – to be published in Sept/Oct
