1. Building an open library without walls : Archiving of particle physics data and results for long-term access and use

ICHEP’06
Parallel session 12: GRID distributed analysis in high energy physics

2. published papers and preprints
When we talk about
archiving results,
what does this mean?
In the past it meant
published papers and preprints
Joanne Yeomans : CERN

3. This has been successful
CERN preprints available as %age of total CERN papers published
HEP arXiv submissions
This has been successful
Joanne Yeomans : CERN

4. What has been possible with preprints up to now?
arXiv and institutional repositories
around 70% of articles available now free in full-text
These repositories of open access (OA) results allow added value which helps users find what they need:
Interlinking of records
Citation extraction and citation linking (backwards and forwards)
Similarity analysis/automatic keyword extraction
Commenting features
OA solution will enable new computational analysis tools which might better automate information retrieval and analysis of results
Different user interfaces possible for different experiments/different people

8. But more is possible… Still more integration could be achieved
eg pre-publication process - writing/internal editorial system
eg publication process - publisher & peer review process
and
Data – long-term accessibility (for re-analysis) and integration with publications and educational materials
What does this mean?
Joanne Yeomans : CERN

9. HEP data Accessibility Use Publications
HEP data is complex (more complex than eg astronomy)
Raw data? Calibrated data? High level objects?
Volume of data, volume/type of access
Experiment/computing environment lifetimes
Use of standards for cross-discipline linking
Use
Accountability issues
Software, human knowledge not encoded
Human aspects : access restrictions, extra work
Need common and persistent vocabulary/ids for citation
Publications
Easier to enhance papers – first step?
Joanne Yeomans : CERN

10. Molecular biology and bioinformatics : ArrayExpress

11. LEP data example
Development by IT of a "museum computing system", based and frozen on existing lxplus technology/software, with access possibilities to (at present CASTOR) mass storage where all data are stored.
the safeguarding of 'standard' analysis framework software and of mini-data on a number of PC’s
the development of a modern C++ analysis framework (in some cases)
the establishment of rules for access to data by non-members of the Collaboration.
Joanne Yeomans : CERN

12. The lessons learned with LEP data
Regardless of open preprint culture, there is no real OA to HEP data
Data becomes either little usable, or little useful (depending on level stored)
Reliance on human memories
Recovery of knowledge should not be prompted by surprises –
what if new LHC discoveries require a re-analysis of LEP data?
Issues are not just technical
Physics community needs to work with IT and Library specialists
Joanne Yeomans : CERN

13. First steps?
Joanne Yeomans : CERN

14. Joanne Yeomans : CERN

15. Possible future
Publish high-level objects behind each scientific paper and integrate with preprints
Publish all high-level objects after the end of the collaboration for later reuse
Use LEP as a case study
More collaboration between information/library groups within different labs
Consider different users and their requirements – researchers outside collaboration, training of students, “educated public”
