Trends in Use of Scientific Workflows: Insights from a Public Repository and Recommendations for Best Practice :

“Scientific workflows are typically used to automate the processing, analysis and management of scientific data. Most scientific workflow programs provide a user-friendly graphical user interface that enables scientists to more easily create and visualize complex workflows that may be comprised of dozens of processing and analytical steps. Furthermore, many workflows provide mechanisms for tracing provenance and methodologies that foster reproducible science. Despite their potential for enabling science, few studies have examined how the process of creating, executing, and sharing workflows can be improved. In order to promote open discourse and access to scientific methods as well as data, we analyzed a wide variety of workflow systems and publicly available workflows on the public repository myExperiment. It is hoped that understanding the usage of workflows and developing a set of recommended best practices will lead to increased contribution of workflows to the public domain.”

SW-MIS: A Semantic Web Based Model for Integration of Institutional Repositories Metadata Records :

“Despite providing a low level of interoperability, the method of Metadata Harvesting is very common within service providers for unifying access to the institutional repositories. On the other hand, the semantic web-based method of Object Reuse and Exchange (ORE) has not been widely adopted by service providers due to its complexity as well as the small number of ORE compatible archives. The purpose of this study is to provide a new metadata integration model, through which resources harvested from repositories are aggregated and converted to Resource Description Format (RDF) so that can take advantage of integrating into the semantic web resources. For the purpose of this study a metadata integration model, namely SW-MIS (Semantic Web-based Metadata Integration System) has been developed, which involves four steps, including: metadata harvesting, exposing harvested metadata, creating Semantic Web compliance data sets, and providing the search and brows interface. For each step, a specific software tool was developed, so that together formed an information workflow system.”

Relationships between users, resources and services in learning object repositories :

“In this paper we describe a proposal for defining the relationships between resources, users and services in a digital repository. Nowadays, virtual learning environments are widely used but digital repositories are not fully integrated yet into the learning process. Our final goal is to provide final users with recommendation systems and reputation schemes that help them to build a true learning community around the institutional repository, taking into account their educational context (i.e. the courses they are enrolled into) and their activity (i.e. system usage by their classmates and teachers). In order to do so, we extend the basic resource concept in a traditional digital repository by adding all the educational context and other elements from end-users’ profiles, thus bridging users, resources and services, and shifting from a library-centered paradigm to a learning-centered one.”

An activity-based costing model for long-term preservation and dissemination of digital research data: the case of DANS :

“Financial sustainability is an important attribute of a trusted, reliable digital repository. The authors of this paper use the case study approach to develop an activity-based costing (ABC) model. This is used for estimating the costs of preserving digital research data and identifying options for improving and sustaining relevant activities. The model is designed in the environment of the Data Archiving and Networked Services (DANS) institute, a well-known trusted repository. The DANS–ABC model has been tested on empirical cost data from activities performed by 51 employees in frames of over 40 different national and international projects. Costs of resources are being assigned to cost objects through activities and cost drivers. The ‘euros per dataset’ unit of costs measurement is introduced to analyse the outputs of the model. Funders, managers and other decision-making stakeholders are being provided with understandable information connected to the strategic goals of the organisation. The latter is being achieved by linking the DANS–ABC model to another widely used managerial tool—the Balanced Scorecard (BSC). The DANS–ABC model supports costing of services provided by a data archive, while the combination of the DANS–ABC with a BSC identifies areas in the digital preservation process where efficiency improvements are possible.”

Digital repositories ten years on: what do scientific researchers think of them and how do they use them?

Posté le par

Digital repositories have been with us for more than a decade, and despite the considerable media and conference attention they engender, we know very little about their use by academics.

This paper sets out to address this by reporting on how well they are used, what they are used for, what researchers’ think of them, and where they thought they were going. Nearly 1,700 scientific researchers, mostly physical scientists, responded to an international survey of digital repositories, making it the largest survey of its kind.

High deposit rates were found and mandates appear to be working, especially with younger researchers. Repositories have made significant inroads in terms of impact and use despite, in the case of institutional repositories, the very limited resources deployed. S

ubject repositories, like arXiv and PubMed Central, have certainly come of age but institutional repositories probably have not come of age yet although there are drivers in place which, in theory anyway, are moving them towards early adulthood.

Setting up an open access digital repository: A case study :

“Setting up of institutional repositories has been gathering momentum in India and many academic and R&D establishments have made it mandatory to set up institutional repositories. This paper briefly details the work that has goneinto setting up and configuring the digital repository of the Ministry of Earth Sciences (MOES). The repository has been setup using the free and open source software, GNU Eprints.org (http://eprints.org). Such a repository will not only help in thewider dissemination of the publications that emerge from the projects and programmes supported by the MOES, but it willalso serve as an information management system for the ministry.”

Improving The Future of Research Communications and e-Scholarship

Posté le par

The dissemination of knowledge derived from research and scholarship has a fundamental impact on the ways in which society develops and progresses, and at the same time it feeds back to improve subsequent research and scholarship.

Here, as in so many other areas of human activity, the internet is changing the way things work; two decades of emergent and increasingly pervasive information technology have demonstrated the potential for far more effective scholarly communication. But the use of this technology remains limited.

Force11 is a community of scholars, librarians, archivists, publishers and research funders that has arisen organically to help facilitate the change toward improved knowledge creation and sharing.

This document highlights the findings of the Force11 workshop on the Future of Research Communication held at Schloss Dagstuhl, Germany, in August 2011: it summarizes a number of key problems facing scholarly publishing today, and presents a vision that addresses these problems, proposing concrete steps that key stakeholders can take to improve the state of scholarly publishing.
