Data Management and Integration in Collaborative Environments

This paper explores the motivation, systems requirements, and solutions for data management and integration within collaborative working environments. It discusses the CoSpaces project, shared data spaces, and the ViroLab virtual laboratory, highlighting the need for dynamic and flexible collaboration models and technologies. The paper concludes with suggestions for future developments in the field.

  1. Data Management and Integration within Collaborative Working Environments Matthias Assel High Performance Computing Center – HLRS University Stuttgart assel@hlrs.de

  2. Outline Motivation Systems Requirements CoSpaces Shared Data Space ViroLab Virtual Laboratory Conclusions ICEIS 2008 Matthias Assel

  3. Motivation What we have… • Distributed teams/groups • Distributed data/information • Distributed workflows What we need… • New collaboration models and technologies • Integration of users, data, workflows, resources • Dynamic and on-demand accessibility • Creation of virtual labs for different domains, e.g. Aerospace, Automotive, Health Care, etc. ICEIS 2008 Matthias Assel

  4. Systems Requirements • Virtualisation of resources/services • Decentralised authentication and authorisation infrastructure • Dynamic access control (policies) • Secure data transmission on several levels • (Automatic) data anonymisation vs. pseudonymisation • Additional policies for storing confidential data sets • Auditing of relevant user interactions • Methods for defining and negotiating service level agreements and Flexibility, Usability, Scalability, Reliability, Performance… ICEIS 2008 Matthias Assel

  5. CoSpaces Project • The CoSpaces project is an IP funded by the EC under the IST Programme of the FP6, which involves 20 European partners and addresses three scientific and technological objectives Evaluate and developcollaborationmodels in innovativecollaborativeworkenvironments (CWE) Createaninnovativedistributed software framework, whichsupports creation of CWE for distributed knowledge workers and teams in collaborative design and engineering tasks Validate the distributed software framework in the Aerospace, Automotive, and Construction sectors ICEIS 2008 Matthias Assel

  6. CoSpaces Shared Data Space • Collaboration data stored in a dedicated shared data space, which is based on a modified version of the BSCW server • Located in the companies’ DMZ • DMZ protected by a separate firewall • User authentication and resource authorisation based on decentralised authentication and authorisation infrastructure (Shibboleth) • Access rights are just granted on data within that data space • Access rights are fully controlled by corresponding data owner • Encryption of entire data traffic ICEIS 2008 Matthias Assel

  7. CoSpaces Shared Data Space ICEIS 2008 Matthias Assel

  8. ViroLab Virtual Laboratory • Funded by EC within the 6th Framework Programme in the • area of integrated biomedical information for better health • 12 partners from 8 different European • countries • Develop a “Virtual Laboratory” for • medical experts that allows clinical • studies and medical knowledge • discovery for HIV drug resistance • Integrate the biomedical information • from viruses, patients, and literature into • a rule-based decision support system for • HIV drug ranking ICEIS 2008 Matthias Assel

  9. ViroLab Data Access and Integration • Usage of established HIV database management system: RegaDB • Data conversion, extraction, and anonymisation occur within each hospital • Set of virtualisation services - Data Access Services (DAS) - that allows users to perform several activities on dispersed data resources • Single/central entry point for all data requests representing the only “visible” and accessible system • Secure data exchange and proper access control for certain resources • Integrated with existing frameworks (Shibboleth, OGSA-DAI) to ease development and improve functionality ICEIS 2008 Matthias Assel

  10. ViroLab Data Access and Integration ICEIS 2008 Matthias Assel

  11. ViroLab Data Access Control ICEIS 2008 Matthias Assel

  12. Conclusion • Collaborative working environments foster cross-organisational data exchange and communication • Most existing systems do not consider the aspects of dynamicity and flexibility well • Presented solutions show two different approaches for collaborative data management and sharing • Future developments should also focus on - Resource and service/application virtualisation - Intelligent searching and recovering capabilities - Context sensitive data access - Reliable tools for monitoring user activities - Pricing and Accounting models ICEIS 2008 Matthias Assel
