Introduction

Supporting and promoting scientific research and innovation as well enabling access to scientific information are key priorities for the European Commission and for the Member States.

The rapid development and adoption of Information and Communication Technologies (ICT) has changed the way researchers work, enabling almost instantaneous collaboration regardless of physical location and has provided access to an enormous amount of scientific information that can be processed on powerful computational platforms. This new way of working has generated and generates a huge volume of data, whose exchange and curation pose significant challenges.

To address this point. the High-Level Expert Group on Scientific Data (also known as HLEG on Scientific Data) recommends in its report (Riding the Wave )  the creation of a directive to set up a unified authentication and authorisation system, which they envision would pave the way to distributed and collaborative authentication, authorisation and accounting (AAA) for scientific data. As a result of the recommendation of the HLEG on Scientific Data, the European Commission has tendered to award funding to study the feasibility and impact of adapting the existing, widely used AAA platforms and services to be fully compliant with the requirements posed by the use of data/information resources (such as papers).

In December 2011 the call for tender was awarded to the Consortium composed of the following four partners:

  • TERENA (Trans European Research and Education Networking Association), the leading partner;
  • LIBER (Association of European Research Libraries);
  • UvA (Universiteit van Amsterdam hereafter called UvA);
  • DEENK (University and National Library of Debrecen)

The consortium will work together with the following experts:

  • Diego Lopez (Telefonica I+D)
  • Klaas Wierenga (Cisco Systems)
  • Torbjorn Wiberg (Umea University)
  • Nicole Harris (JISC Advance)

This study will run from Dec 2011 until August 2012.

 

Aim of the Study

The goal of this study is to provide recommendations for the development and deployment of a Scientific Data e-Infrastructure (SDI) that would enable access to heterogonous data for researchers and citizens alike. The SDI should be delivered integrating as much as possible existing AAA platforms (such as those used by the research and education community, or those used by the eScience community).

The study will therefore will identify use-cases for the SDI; it will assess existing AAA-infrastructures as well as the ability for the existing AAA-infrastructures to address these use-cases; the study will also examine the gaps in providing the necessary infrastructure to support the use-cases and explore the work that is being done in the existing AAA-infrastructures to address those needs.

The results of the study in the forms of technical and policy recommendations will be used in developing a strategy, in particular, for Scientific Data Infrastructures in Europe that will support science by providing access to quality services for researchers, funding agencies and for the public at large.

The targeted actors in the study are the research and education communities, information service providers (data centres, libraries) and e-Infrastructure/technology providers.

 

General Study Organization

The goal of the study will be achieved by meeting three different objectives:

Objective I – Identify use-cases and their requirements concerning AAA

During this phase of the study, use-cases will be identified via interviews with different user-groups; particularly LIBER and DEENK will collect the requirements from the library, the archive and the humanity communities on data access, data management and governance, data curation and long-term preservation as well as on AAA; TERENA and UvA will collect to requirements from the e-Science and to the networking communities.

The results of these interviews will be used to assess how the existing initiatives can meet the resulting requirements. The rationale for the SDI and its added value to access, store and preserve heterogeneous data will also be highlighted.

Objective II – Analyse existing and emerging infrastructures to address identified use-cases.

A strengths and weaknesses study (SWOT Analysis) of the existing infrastructures will be carry out; during this phase the support for the identified use-cases will also be assessed. Data protection, access issues and trust models will also be considered.

This part of the study will be driven mostly by TERENA, UvA and the experts.

This part of the study will also describe scenarios that would benefit from an integrated AAA and evaluate options to deliver an integrated and manageable AAA/AAI for the SDI (or e-Infrastructure).

The outcome of this part of the study will be:

  • A complete overview of the AAA landscape in Europe (with references to US and/or other regions) and the main current trends;
  • A description of the inter-operability features of the AAA systems surveyed in light of their suitability as elements of integrated infrastructures.
  • An evaluation of the user-friendliness of the considered AAA infrastructures.

Objective III – Recommendations to deliver the SDI

In the third part of the study options to deliver an integrated and manageable AAI for SDI (Objective 3) will be proposed.

The outcome of this study will be:

  • Provide recommendations for adapting the existing, widely used platforms and services to be fully compliant with the requirements posed by the use of data/information resources (papers, catalogues, raw data, images, etc)
  • Provide recommendations on how European regulations could support such an integrated SDI;
  • Provide technical recommendations for developers to favour specific technologies to ensure future inter-operability;
  • Address the (organizational, legal and technical) challenges to provide pan-Europe AAA/AAI for SDI/e-Infrastructure.

The role of new technologies and standards under development in relevant bodies such as IETF, OGF, OASIS, ISO/ITU-T, IEEE as well as industry technologies (social network and others)  and how these will impact of facilitate the provisioning of the SDI will be discussed.



Timetable, Deliverables, and Meetings

The study will be done in period from January 2012 till August 2012 with the following deliverables and timetable.

D1 - Inception report (February 2011) will elaborate on the methodology that will be used to carry out the study, will provide details on the resources and articulate the objectives.

D2 - Interim study report (April 2012) will cover the intermediate results for the objectives listed above, specifically:

Objective 1: the state-of-the-art survey will be in its final stage and complete.

TERENA and UvA will lead the work to assess the state-of-the art of the existing AAA infrastructures used by the research and education community.

Objective 2: some technical, organisational and legal obstacles will be identified in the analysed AAA Infrastructures and initial proposals will be formulated, specifically on how to overcome the barriers to effectively move towards the provision of common cross-domain and European-wide AAA services suitable for information resources.

The interim report will include initial set of use-cases collected by partners, in particular:

(i) LIBER and DEENK will collect the requirements from the library, the archive and the humanity communities on data access, data management and governance, data curation and long-term preservation as well as on AAA.

(ii) TERENA and UvA will collect to requirements from the e-Science and to the networking communities.

The initial requirements for the AAA infrastructure will be derived by the use-cases; the assessed AAA infrastructures will also be evaluated against the collected use-cases. A SWOT analysis of these infrastructures will be provided as part of this report.

D3 - Final study report (June 2012), including an executive summary, covering the final results for the objectives listed above. The final study report will take into account the discussions at the Final workshop (planned for July 2012) and final meeting as well as the use-communities identified and consulted by the consortium. An annex to the final study report will contain the raw data used in producing the study.

D4  - Technical report (July 2012) which will describe the use of resources in the performance of the contract including e.g. time-sheets on man/days consumption, travel details, use of consumables, etc.

Final workshop will be organised in July 2012 to discuss results if the study and findings to be presented in the Final study report. During this meeting a draft of the final study report will be presented. The workshop will be organised at the Commission’s premises in Brussels.

Consortium

TERENA (http://www.terena.org) has extensive and consolidated experience in leading pan-European initiatives and large-scale studies. TERENA operates under a model in which experts with the appropriate competence and experience from the national academic networks and the research community collaborate in the well-established initiatives operating under the TERENA’s umbrella, such as the Research and Education FEDerationS (REFEDS) initiative, the task-force on European Middleware Coordination and Collaboration (TF-EMC2) and the task-force on Mobility and Network Middleware (TF-MNM). Through the leadership of these groups (who have committed to participating in this study) and through TERENA’s participation in the GÉANT project, TERENA can provide extraordinary resources and knowledge for the task at hand: assessing the AAA-infrastructures operated by (and for) the European R&E community, define the requirements of this community for the next decade and propose recommendations to build the Scientific Data infrastructure (SDI).

LIBER  (http://www.libereurope.eu) offers a network of 425 institutions (major research libraries in Europe) in more than 40 countries, which will prove very useful for consultation, dissemination and awareness raising; LIBER is also well positioned to offer a more political level consultation and outreach via the League of European Research Universities (LERU) and other major research institutes. Large scale survey experience is another main asset that LIBER will bring to the Consortium.

UvA (http://www.science.uva.nl/research/sne/) will contribute to the project study with expert knowledge in the area of Authentication and Authorisation Infrastructure (AAI) and emerging security models for Cloud and on-demand infrastructure services provisioning to achieve federated Authentication, Authorisation and Attributes management in heterogeneous distributed e-Science applications. Existing expertise will be effectively used for proposing a common integrated and/or federated AAA infrastructure for all components and layers of the Scientific Data infrastructure (SDI). UvA has developed generic authentication, authorisation and accounting (AAA) architecture and AAA Authorisation frameworks (described in RFC2903-2906) and provided practical implementation with the open source GAAA (Generic AAA) Toolkit Library used in a number of EU funded projects like GEYSERS (Generalised Architecture for Dynamic Infrastructure Services), Phosphorus (Lamba User Controlled Infrastructure for European Research), EGEE (Enabling Grid from E-sciencE) and others. UvA is active in many standardisation bodies including OGF (http://www.ogf.org), IETF (http://www.ietf.org) and NIST (http://www.nist.gov).

DEENK (http://www.lib.unideb.hu) is one of the leading university libraries with important national tasks in Hungary. DEENK operates the infrastructure of the National Document Supply System including the electronic document service. It provides technical support for the Hungarian Open Repository Network (HUNOR) and brings to the consortium a key role in open access initiatives both on national and international levels as well as the experience gained in developing an electronic archive to store scholarly outputs as one of the first universities in Hungary. It hosts the Open Access National website containing up-to-date information about open access events and projects.
