Research has become increasingly reliant on extensive data. The integration, sharing and reuse of research data poses a significant challenge, particularly in the context of interdisciplinary collaborative projects. An essential objective for a research infrastructure dedicated to data management is to facilitate efficient data discovery and integr...

The concept of a "Research Data Commons" (RDC) established itself as an infrastructure ecosystem for science based on open standards and federated resources to facilitate the sharing of research data and services. The consortia of the German National Research Data Infrastructure (NFDI) have identified the collaborative provisioning of resources and...

The information system PANGAEA provides targeted support for research data management as well as long-term data archiving and publication. PANGAEA is operated as an open access library for archiving, publishing, and distributing georeferenced data from earth and environmental sciences. It focuses on observational and experimental data. Citability,...

Rapid changes of the biosphere observed in recent years are caused by both small and large scale drivers, like shifts in temperature, transformations in land-use, or changes in the energy budget of systems. While the latter processes are easily quantifiable, documentation of the loss of biodiversity and community structure is more difficult. Change...

Funders and policy makers have strongly recommended the uptake of the FAIR principles in scientific data management. Several initiatives are working on the implementation of the principles and standardized applications to systematically evaluate data FAIRness. This paper presents practical solutions, namely metrics and tools, developed by the FAIRs...

Background: The NFDI process in Germany The digital revolution is fundamentally transforming research data and methods. Mastering this transformation poses major challenges for stakeholders in the domains of science and policy. The process of digitalisation creates immense opportunities, but it must be structured proactively. To this end, the estab...

Exemplified on the information system PANGAEA, we describe the application of terminologies for archiving and publishing environmental science data. A Terminology Catalogue (TC) was embedded into the system, with interfaces allowing to replicate and to manually work on terminologies. For data ingest and archiving, we show how the TC can improve str...

While literature portals in the biomedical domain already enhance their search applications with ontological concepts, data portals offering biological primary data still use a classical keyword search. Similar to publications, biological primary data are described along meta information such as author, title, location and time which is stored in a...

Purpose Research data publishing is today widely regarded as crucial for reproducibility, proper assessment of scientific results, and as a way for researchers to get proper credit for sharing their data. However, several challenges need to be solved to fully realize its potential, one of them being the development of a global standard for links be...

The Scholix Framework (SCHOlarly LInk eXchange) is a high level interoperability framework for exchanging information about the links between scholarly literature and data, as well as between datasets. Over the past decade, publishers, data centers, and indexing services have agreed on and implemented numerous bilateral agreements to establish bidi...

Although research data publishing is today widely regarded as crucial for reproducibility and proper assessment of scientific results, several challenges still need to be solved to fully realize its potential. Developing links between the published literature and datasets is one of them. Current solutions are mostly based on bilateral, ad-hoc agree...

The International Polar Year (IPY) 2007–2008 was a synchronized effort to simultaneously collect data from polar regions. Being the fourth in a series of IPYs, the demand for interdisciplinarity and new data products was high. However, despite all the research done on land, people, ocean, ice and atmosphere and the large amount of data collected, n...

The first minting of Digital Object Identifiers (DOI) for research data happened in 2004 in the context of the project " Publication and citation of primary scientific data " (STD-DOI). Some of the concepts and perceptions about DOI for data today have their roots in the way this project implemented DOI for research data and the decisions made in t...

The International Polar Year 2007–2008 was a synchronized effort to simultaneously collect data from polar regions. Being the fourth in a row of IPYs, the demand for interdisciplinarity and new data products was high. However, despite of all the research done on land, people, ocean, ice and atmosphere and the large amount of data collected, no cent...

Scientific ocean drilling began in 1968 and ever since has been generating huge amounts of data, including that from shipboard analysis of cores, in situ borehole measurements, long-term subseafloor hydrogeological observatories, and post-expedition research done on core samples and data at laboratories around the world (Smith et al., 2010). Much o...

Environmental and climate changes are crucial challenges for sustainable living because of their significant impact on the Earth system and the important consequences for natural resources. Oceans have a primary role in these changes as they regulate heat flux, greenhouse gases and climate whilst harboring many different life forms and resources. U...

Biodiversity research brings together the many facets of biological environ-mental research. Its data management is characterized by integration and is particu-larly challenging due to the large volume and tremendous heterogeneity of the data. At the same time, it is particularly important: A lot of the data is not reproducible. Once it is gone, po...

Search engines like Google have changed the way scientists are searching for publications and data. Users are accustomed to a single input line to enter search terms.

The project ESONET which is coordinated by IFREMER, France, is a European initiative towards establishing new -and making use of existing- ocean observatories around Europe for observing natural processes that are either very episodic or statistically require long time series. The most important processes are: (1) the episodic release of methane fr...

Intensive research in the earth sciences over the past decades has created a tremendous wealth of literature, data, and material collections. So far, literature, data and sample collections have been separated. Information technology and the internet, in particular the new cyberinfrastructures for the earth sciences, offer ways to interlink literat...

The 'Berlin Declaration' was published in 2003 as a guideline to policy makers to promote the Internet as a functional instrument for a global scientific knowledge base. Because knowledge is derived from data, the principles of the 'Berlin Declaration' should apply to data as well. Today, access to scientific data is hampered by structural deficits...

During the past few years there has been a growing interest in climate and environmental research topics. Activities in this field generate and require massive amounts of highly diverse data and information which is needed to document change and to improve understanding of processes affecting our climate. Because these issues are so broad, a data a...

Numerous methods for roundness measurement have been developed. None, however, has been generally accepted, because of conceptual and practical deficiencies. Modern image processing and Fourier grain shape analysis have eliminated the practical shortcomings, but the conceptual ones remained. Single, higher harmonics of the Fourier series, for examp...

We present a generic portal system architecture suitable for geoscientific data portals. The portals harvest data providers with Open Archives Initiative (OAI) protocols using XML based metadata formats like DIF or ISO-19139 format. Current implementations of OAI only support Dublin Core metadata. The new Java based portal software will sup-port an...
