Audit and Certification of Digital Repositories: Creating a Mandate for the Digital Curation Centre (DCC)
The article examines the issues surrounding the audit and certification of digital repositories in light of the work that the RLG/NARA Task Force did to draw up guidelines and the need for these guidelines to be validated.
Roles and responsibilities: Libraries, librarians and data.
Reviews opportunities and challenges for libraries and librarians in the research data arena, with reference to published reports and case studies of emerging practice, supplemented by evidence from university and library websites. Looks at connections between research data management (RDM) and established library roles and responsibilities to explore whether RDM represents an incremental step in professional practice or a paradigm shift in collection development and service delivery requiring fundamental rethinking of roles, responsibilities, and competencies to create “next-generation librarianship,” drawing on experiences and opinions of practitioners in the field. Also discusses professional education and continuing development needs for library engagement with research data, referring particularly to initiatives in the USA
A Taxonomy of Data Grids for Distributed Data Sharing, Management and Processing
Data Grids have been adopted as the platform for scientific communities that
need to share, access, transport, process and manage large data collections
distributed worldwide. They combine high-end computing technologies with
high-performance networking and wide-area storage management techniques. In
this paper, we discuss the key concepts behind Data Grids and compare them with
other data sharing and distribution paradigms such as content delivery
networks, peer-to-peer networks and distributed databases. We then provide
comprehensive taxonomies that cover various aspects of architecture, data
transportation, data replication and resource allocation and scheduling.
Finally, we map the proposed taxonomy to various Data Grid systems not only to
validate the taxonomy but also to identify areas for future exploration.
Through this taxonomy, we aim to categorise existing systems to better
understand their goals and their methodology. This would help evaluate their
applicability for solving similar problems. This taxonomy also provides a "gap
analysis" of this area through which researchers can potentially identify new
issues for investigation. Finally, we hope that the proposed taxonomy and
mapping also helps to provide an easy way for new practitioners to understand
this complex area of research.Comment: 46 pages, 16 figures, Technical Repor
Adding eScience Assets to the Data Web
Aggregations of Web resources are increasingly important in scholarship as it
adopts new methods that are data-centric, collaborative, and networked-based.
The same notion of aggregations of resources is common to the mashed-up,
socially networked information environment of Web 2.0. We present a mechanism
to identify and describe aggregations of Web resources that has resulted from
the Open Archives Initiative - Object Reuse and Exchange (OAI-ORE) project. The
OAI-ORE specifications are based on the principles of the Architecture of the
World Wide Web, the Semantic Web, and the Linked Data effort. Therefore, their
incorporation into the cyberinfrastructure that supports eScholarship will
ensure the integration of the products of scholarly research into the Data Web.Comment: 10 pages, 7 figures. Proceedings of Linked Data on the Web (LDOW2009)

Analysis of simulation environment
In this paper the requirements for an ALN simulation environment are analysed, as needed in the CATNETS Project. A number of grid and general purpose simulators are evaluated regarding the identified requirements for simulating economical resource allocation mechanisms in ALNs. Subsequently a suitable simulator is chosen for usage in the CATNETS project. --CATNETS simulator,requirements analysis,simulator selection
Nordic LifeWatch cooperation, final report: A joint initiative from Denmark, Iceland, Finland, Norway and Sweden
The main goal of the present report is to outline the possibilities for an enhanced cooperation between the Nordic countries within eScience and biodiversity. LifeWatch is one of several ESFRI projects which aim to establish eInfrastructures and databases in the field of biodiversity and ecosystem research.
Similarities between Nordic countries are extensive in relation to a number of biodiversity related issues. Most species in Nordic countries are common, and frequently the same challenges concerning biodiversity and ecosystem services are addressed in the different countries.
The present report has been developed by establishing a Nordic LifeWatch network with delegates from each of the Nordic countries. The report has been written jointly by the delegates, and the work was organized by establishing working groups with the following themes: strategic issues, technical development, legal framework and communication.
Written during two workshops, Skype meetings and emailing, the following main issues are discussed in the present report:
* Scientific needs for improved access to biodiversity data and advanced eScience research infrastructure in the Nordic countries.
* Future challenges and priorities facing the international biodiversity research community.
* Scientific potential of openly accessible biodiversity and environmental data for individual
researchers and institutions.
* Spin-off effects of open access for the general public.
* Internationally standardized Nordic metadata inventory.
* Legal framework and challenges associated with environmental-, climate-, and biodiversity
data sharing, communication, training and scientific needs.
* Finally, some strategic steps towards realizing a Nordic LifeWatch construction and
operational phase are discussed.
Easy access to open data on biodiversity and the environment is crucial for many researchers and research institutions, as well as environmental administration. Easy access to data from different fields of science creates an environment for new scientific ideas to emerge. This potential of generating new, interdisciplinary approaches to pre-existing problems is one of the key features of open-access data platforms that unify diverse data sources. Interdisciplinary elements, access to data over larger gradients, compatible eSystems and eTools to handle large amounts of data are extremely important and, if further developed, represent significant steps towards analysis of biological effects of climate change, human impact and development of operational ecosystem service assessment techniques.
It is concluded that significant benefits regarding both scientific potential, technical developments and financial investments can be obtained by constructing a common Nordic LifeWatch eInfrastructure.
Several steps concerning organizing and funding of a future Nordic LifeWatch are discussed, and an action plan towards 2020 is suggested. To analyze the potential for future Nordic LifeWatch in detail, our main conclusion is to arrange a Nordic LifeWatch conference as soon as possible. This conference should involve Nordic research councils, scientists and relevant stakeholders. The national delegates from the participating countries in the Nordic LifeWatch project are prepared to present details from the report and developments so far as a basis for further development of Nordic LifeWatch.
The present work is financed by NordForsk and in-kind contributions from participating institutions
Towards Interoperable Research Infrastructures for Environmental and Earth Sciences
This open access book summarises the latest developments on data management in the EU H2020 ENVRIplus project, which brought together more than 20 environmental and Earth science research infrastructures into a single community. It provides readers with a systematic overview of the common challenges faced by research infrastructures and how a ‘reference model guided’ engineering approach can be used to achieve greater interoperability among such infrastructures in the environmental and earth sciences. The 20 contributions in this book are structured in 5 parts on the design, development, deployment, operation and use of research infrastructures. Part one provides an overview of the state of the art of research infrastructure and relevant e-Infrastructure technologies, part two discusses the reference model guided engineering approach, the third part presents the software and tools developed for common data management challenges, the fourth part demonstrates the software via several use cases, and the last part discusses the sustainability and future directions
