A Concept for Attribute-Based Authorization on D-Grid Resources

In Germany's D-Grid project numerous Grid communities are working together to provide a common overarching Grid infrastructure. The major aims of D-Grid are the integration of existing Grid deployments and their interoperability. The challenge lies in the heterogeneity of the current implementations: three Grid middleware stacks and different Virtual Organization management approaches have to be embraced to achieve the intended goals. In this article we focus oil the implementation of an attribute-based authorization infrastructure that not only leverages the well-known VO attributes but also campus attributes managed by a Shibboleth federation

A Network of Text, Data and People for the Earth System Sciences

Earth System Science is an outstanding example of a field of research which yields important results especially when conducted in multidisciplinary and global cooperation. The International Polar Year and its expected legacy are used as an example to illustrate this assertion and the financial and intellectual expense invested. It follows that any effort to make more out of the globally distributed – if not fragmented – results and to network the knowledge gained would be valuable indeed. An experimental implementation of such a system, connecting journal articles to datasets, expeditions and researchers involved, is introduced. Some developments necessary to implement comparable and more powerful systems on a global scale are discussed

EXPEDITION - An integrated approach to expose expedition information and research results

The portal EXPEDITION offers an integrative “one-stop-shop” framework for discovery and re-use of scientific content originating from research platforms operated by the Alfred Wegener Institute (AWI). This information sharing framework is designed for interoperability and can be extended to various information systems worldwide. The framework is based on open technologies and access is freely available for scientists, funding agencies and the public. Because AWI’s research is known to be focused on both Polar Regions, access to various ready-to-use data products from the Arctic Ocean, the Southern Ocean and Antarctic as well as AWI-operated observing networks will be offered

Scientific Discourse in the Digital Era: A Statement

[Session abstract] The panel will discuss the character of scientific discourse in the digital era by considering these questions. • How has the character of scientific discourse developed in the digital era? o In what ways have digital technologies influenced traditional scientific discourse? o How will this influence evolve in the 21st century in basic and applied research? • What is the reality of, and potential for, inter-, cross- and trans-disciplinary discourse in the sciences in the digital era? • Define the issues and potential resolutions in the relationship between scientific discourse and policy, governance, management, adaptation, and mitigation regimes? • In what manner is scientific discourse socially constructed? • How should research data, on which scientific analyses are based, be reviewed, valued, and shared
