    Eprints and the Open Archives Initiative

    Full text link
    The Open Archives Initiative (OAI) was created as a practical way to promote interoperability between eprint repositories. Although the scope of the OAI has been broadened, eprint repositories still represent a significant fraction of OAI data providers. In this article I present a brief survey of OAI eprint repositories, and of services using metadata harvested from eprint repositories using the OAI protocol for metadata harvesting (OAI-PMH). I then discuss several situations where metadata harvesting may be used to further improve the utility of eprint archives as a component of the scholarly communication infrastructure.Comment: 13 page

    Technical alignment

    This essay discusses the importance of the areas of infrastructure and testing to help digital preservation services demonstrate reliability, transparency, and accountability. It encourages practitioners to build a strong culture in which transparency and collaborations between technical frameworks are valued highly. It also argues for devising and applying agreed-upon metrics that will enable the systematic analysis of preservation infrastructure. The essay begins by defining technical infrastructure and testing in the digital preservation context, provides case studies that exemplify both progress and challenges for technical alignment in both areas, and concludes with suggestions for achieving greater degrees of technical alignment going forward

    RIOJA (Repository Interface to Overlaid Journal Archives) project: final report

    RIOJA (Repository Interface to Overlaid Journal Archives) was a 18-month partnership between UCL (University College London), Imperial College London, and the Universities Glasgow, Cambridge and Cornell. The project was funded by the JISC (Joint Information Systems Committee, UK). The project team worked with the Astrophysics community investigate aspects of overlay journals. For the purposes of the project, an overlay was defined as a quality-assured journal whose content is deposited to and resides more open access repositories. The project had both technical aims and supporting, non-technical aims. The primary technical deliverable from the project was a toolkit for the creation and maintenance overlay journals. The toolkit supports the exchange of data between a repository and piece of journal software. It supports functions such as author validation, metadata extraction from the source repository, and submission tracking. The toolkit is platform-neutral and could, in theory, be employed by any journal using content from any number repositories, in any discipline. The project also implemented a demonstrator overlay applying the RIOJA toolkit to the arXiv subject repository, and a demonstrator implementation of the RIOJA tool for GNU EPrints. Aside from creating the demonstrator and its underlying tools, the project aimed to acceptibility and feasibility of the overlay model. First, a large-scale survey of the Astrophysics community was undertaken. The survey collected data about research publishing practices within this community, and probed its reaction to the principle publishing. Second, the views of editors and publishers in this discipline were sought through interviews. These views were added to findings from the literature and summarised in a more general report on issues around the sustainability of an overlay journal

    Electronical Health Record's Systems. Interoperability

    Understanding the importance that the electronic medical health records system has, with its various structural types and grades, has led to the elaboration of a series of standards and quality control methods, meant to control its functioning. In time, the electronic health records system has evolved along with the medical data's change of structure. Romania has not yet managed to fully clarify this concept, various definitions still being encountered, such as "Patient's electronic chart", "Electronic health file". A slow change from functional interoperability (OSI level 6) to semantic interoperability (level 7) is being aimed at the moment. This current article will try to present the main electronic files models, from a functional interoperability system's possibility to be created perspective. \ud \u

    A Framework to Evaluate Software Developer’s Productivity The VALORTIA Project

    Get PDF
    Currently, there is a lack in companies developing software in relation to assessing their staff’s productivity before executing software projects, with the aim of improving effectiveness and efficiency. QuEF (Quality Evaluation Framework) is a framework that allows defining quality management tasks based on a model. The main purpose of this framework is twofold: improve an entity’s continuous quality, and given a context, decide between a set of entity’s instances on the most appropriate one. Thus, the aim of this paper is to make this framework available to evaluate productivity of professionals along software development and select the most appropriate experts to implement the suggested project. For this goal, Valortia platform, capable of carrying out this task by following the QuEF framework guidelines, is designed. Valortia is a platform to certify users' knowledge on a specific area and centralize all certification management in its model by means of providing protocols and methods for a suitable management, improving efficiency and effectiveness, reducing cost and ensuring continuous quality.Ministerio de Ciencia e Innovación TIN2013-46928-C3-3-

    Dynamic Trust Federation in Grids

    No full text
    Grids are becoming economically viable and productive tools. Grids provide a way of utilizing a vast array of linked resources such as computing systems, databases and services online within Virtual Organizations (VO). However, today’s Grid architectures are not capable of supporting dynamic, agile federation across multiple administrative domains and the main barrier, which hinders dynamic federation over short time scales is security. Federating security and trust is one of the most significant architectural issues in Grids. Existing relevant standards and specifications can be used to federate security services, but do not directly address the dynamic extension of business trust relationships into the digital domain. In this paper we describe an experiment in which we highlight those challenging architectural issues and we will further describe how the approach that combines dynamic trust federation and dynamic authorization mechanism can address dynamic security trust federation in Grids. The experiment made with the prototype described in this paper is used in the NextGRID project for the definition of requirements for next generation Grid architectures adapted to business application need
