D4Science-II Data Infrastructures Ecosystem for Science (D4Science-II)

Published on: 19/05/2010

D4Science-II is an European e-Infrastructure project, co-funded by the European Commission in the frame of the Seventh Framework Programme for Research and Technological Development and it constitutes a continuation of the DILIGENT and D4Science projects.

The main aim of the D4Science-II project is to provide mechanism for facilitating interoperation of the D4Science e-Infrastructure with diverse other data e-Infrastructures that are at the present phase running autonomously, thus creating the core of an e-Infrastructure Ecosystem. These e-Infrastructure Ecosystems will serve a significantly expanded set of communities dealing with multidisciplinary, scientific and societal challenges. To achieve this scope, the project will bring together several scientific e-Infrastructures in areas such as biodiversity, fishery resources management and high energy physics; initially, this core will include: AQUAMAPS, DRIVER, GENESI-DR and INSPIRE that are distinct initiatives but at the same time inter-related.

In collaboration with appropriate international bodies and initiatives, D4Science-II will take steps to ensure sustainability of the Knowledge Ecosystem; as a conclusion, a more powerful model in which e-Infrastructures are not isolated but dynamically interoperate and influence each other as the components of an ecosystem will be introduced with the creation of a D4Science-II Knowledge Ecosystem.  The project will focus on the deployment and exploitation of mechanisms and policies for the interoperability of application-level infrastructures and infrastructural services.

Description of the way to implement the initiative

The objectives of D4Science-II are being achieved through the synergetic operation of Networking, Service, and Joint Research Activities.

  • D4Science-II Networking Activities (NA): these activities establish a cooperation channel with the key players of the initiative, thus supporting the building of the previously mentioned knowledge ecosystem and foster the exploitation of the resulting ecosystem by scientific communities involved in global research challenges; large research communities will be involved, projects outcomes will be widely disseminated and training will be organised for the various players and decision makers.
  • D4Science-II Service Activities (SA): these activities aim at providing the key players and large research communities internal to the project or attracted through the Networking Activities with the services implementing the envisaged Ecosystem and Virtual Research Environments. To achieve this goal, activities, procedures and mechanisms will be put in place.
  • D4Science-II Joint Research Activities (JRA): these activities will implement the technology supporting the vision predicated by the D4Science-II project. The D4Science technology – gCube – will be kept as a firm base and it will be expanded so as to meet the novel expectations emerging from the D4Science-II application scenario. the technology needed to bridge the target e-Infrastructures and services with D4Science will be also implemented and, at the same time, the approaches to render D4Science facilities exploitable by service providers in programmatic way will be empowered. As a consequence, the innovative services envisaged in the target scenario will become possible and will be implemented to demonstrate the effectiveness of the knowledge ecosystem in challenging research scenarios.


Technology solution

The D4Science-II enabling technology is gCube an innovative service-based, autonomic, Virtual Research Environment (VRE) management system; the system supports the declarative and interactive creation of transient VREs that aggregate and deploy on-demand content resources and application services by exploiting computational and storage resources of a grid infrastructure.

Technologically, D4Science-II constitutes a continuation of the DILIGENT and D4Science projects, which have initiated an effort towards using existing network, grid, and repository infrastructures to deploy on top of them a pan-European research e-Infrastructure that will enable unlimited generation and dissemination of scientific knowledge. As the next step towards this goal, D4Science-II will transform the current, operational D4Science e-Infrastructure into the linchpin of an e-Infrastructure Ecosystem, holding together and mediating between all participating e-Infrastructures through programmatically-available interoperability services.

The project will therefore develop methodologies to enable the sustainable interoperability of heterogeneous data e-infrastructures which are at the moment running independently.

Technology choice: Standards-based technology, Open source software
