Grid infrastructures for secure access to and use of bioinformatics data: experiences from the BRIDGES project

The BRIDGES project was funded by the UK Department of Trade and Industry (DTI) to address the needs of cardiovascular research scientists investigating the genetic causes of hypertension as part of the Wellcome Trust funded (£4.34M) cardiovascular functional genomics (CFG) project. Security was at the heart of the BRIDGES project and an advanced data and compute grid infrastructure incorporating latest grid authorisation technologies was developed and delivered to the scientists. We outline these grid infrastructures and describe the perceived security requirements at the project start including data classifications and how these evolved throughout the lifetime of the project. The uptake and adoption of the project results are also presented along with the challenges that must be overcome to support the secure exchange of life science data sets. We also present how we will use the BRIDGES experiences in future projects at the National e-Science Centre

Towards data grids for microarray expression profiles

The UK DTI funded Biomedical Research Informatics Delivered by Grid Enabled Services (BRIDGES) project developed a Grid infrastructure through which research into the genetic causes of hypertension could be supported by scientists within the large Wellcome Trust funded Cardiovascular Functional Genomics project. The BRIDGES project had a focus on developing a compute Grid and a data Grid infrastructure with security at its heart. Building on the work within BRIDGES, the BBSRC funded Grid enabled Microarray Expression Profile Search (GEMEPS) project plans to provide an enhanced data Grid infrastructure to support richer queries needed for the discovery and analysis of microarray data sets, also based upon a fine-grained security infrastructure. This paper outlines the experiences gained within BRIDGES and outlines the status of the GEMEPS project, the open challenges that remain and plans for the future

Position Paper: Secure Infrastructure for Scientific Data Life Cycle Management

Abstract—Within the Austrian Grid project phase 2, three different groups, each allocated to a different workpackage, join their efforts to implement a grid infrastructure for the european research project “Breath Gas Analysis for molecular oriented diseases”. This position paper provides background on the task and the resulting requirements, a presentation on solutions developed during related projects in the application domain, identifies problems that have not yet been solved, and finally presents the intended solution to be developed. I. INTRODUCTION & CONTEXT This position paper describes the current state, the in-tended realisation and a discussion of the project Grid Breath Gas Analysis (BAMOD-Grid) carried out withi

Development of a grid infrastructure for functional genomics

The BRIDGES project is incrementally developing and exploring database integration over six geographically distributed research sites with the framework of a Wellcome Trust biomedical research project (the Cardiovascular Functional Genomics project) to provide a sophisticated infrastructure for bioinfomaticians. Grid technologies are being used to facilitate this integration. Key issues to be investigated in BRIDGES are data integration and data federation, security, user friendliness, access to large scale computational facilities and incorporation of existing bioinformatics software solutions, both for visualisation as well as analysis of genomic data sets. This paper outlines the initial experiences in applying Grid technologies and outlines the on-going designs put forward to address these issues
