First Workshop on Data Preservation and Long Term Analysis in HEP

26 Jan 2009, 08:00 → 28 Jan 2009, 18:00 Europe/Zurich

Seminar 4 (EVO) (DESY)

Cristinel Diaconu

26-28 January, 2009 Experiments close to the end of the data taking initiate with this workshop a common reflection on data persistency and long term analysis in order to get a common vision on these issues and create a multi-experiment dynamics for further reference. It is foreseen that the workshop is a starting point for intense consultations and common work on defined subject. A second follow-up workshop will take place mid 2009. The objectives of the workshop are: *Review and document the physics objectives of the data persistency in HEP. *Exchange information concerning the analysis model: abstraction, software, documentation etc. and identify coherence points. *Address the harware and software persistency status *Review possible fundings programs and other related international initiatives. *Converge to a common set of specifications in a document that will constitute the basis for future collaborations. This workshop is an expert level meeting and the participation is by invitation only. The web site of the study group is www.dphep.org

09:00 → 12:20 Reports from Experiments: Data Analysis and Computing Models

The aim of this session is to get a global overview of various types of data analysis models in HEP. The presentations are structured according to an agreed scheme such that comparisons can be made and common aspects are identified. The experiments are also invited to give their views on the long term strategies in order to prepare the discussions on future common actions.
