    How FAIR can you get? Image Retrieval as a Use Case to calculate FAIR Metrics

    Full text link
    A large number of services for research data management strive to adhere to the FAIR guiding principles for scientific data management and stewardship. To evaluate these services and to indicate possible improvements, use-case-centric metrics are needed as an addendum to existing metric frameworks. The retrieval of spatially and temporally annotated images can exemplify such a use case. The prototypical implementation indicates that currently no research data repository achieves the full score. Suggestions on how to increase the score include automatic annotation based on the metadata inside the image file and support for content negotiation to retrieve the images. These and other insights can lead to an improvement of data integration workflows, resulting in a better and more FAIR approach to manage research data.Comment: This is a preprint for a paper accepted for the 2018 IEEE conferenc

    StreamOnTheFly: a network for radio content dissemination

    Get PDF
    A distributed digital library has been designed and implemented for the support of community radios. This framework, developed by the StreamOn- TheFly IST project of the EU, provides a common background for preparation, archival, exchange and reuse of radio programs and supports radio personalization. The architecture is based on a decentralized network of software components using automatic metadata replication in a peer-to-peer manner. This approach combines the principles and practice of OAI (Open Archives Initiative) with the peer-to-peer networking paradigm, and extends usual content dissemination with the aggregation of use statistics and user feedback. The network also promotes social self-organization of the community and a new common metadata schema and content exchange format

    A Digital Registry for Archaeological Find Spots and Excavation Documentation in IANUS

    Grey literature (site notebooks, reports etc.) and research data in archaeology are invaluable sources of information currently lacking a central reference registry in Germany. This paper discusses requirements and the underlying data model of a registry to be developed for find spots and archaeological excavation data within the IANUS project at the German Archaeological Institute. This registry is to collect information on archaeological investigations data for a finding aid service. The focus for this registry will be based on the collection of metadata about primary data and grey literature, not on secondary data or on publications. Starting with the acquisition of basic metadata needs drawn from the IANUS mission and project charter. A review of already existing projects and initiatives in this field (EDNA, tDAR, ADS, Open Context) provides more details about which information should be captured during a registration of research data for a long term digital preservation archive. Finally recommendations for the data model of this registry are drawn from the evaluation of existing generic and archaeology-specific metadata standards (Dublin Core, EDM, LIDO, ADeX, CARARE)

    The INCF Digital Atlasing Program: Report on Digital Atlasing Standards in the Rodent Brain

    Get PDF
    The goal of the INCF Digital Atlasing Program is to provide the vision and direction necessary to make the rapidly growing collection of multidimensional data of the rodent brain (images, gene expression, etc.) widely accessible and usable to the international research community. This Digital Brain Atlasing Standards Task Force was formed in May 2008 to investigate the state of rodent brain digital atlasing, and formulate standards, guidelines, and policy recommendations.

Our first objective has been the preparation of a detailed document that includes the vision and specific description of an infrastructure, systems and methods capable of serving the scientific goals of the community, as well as practical issues for achieving
the goals. This report builds on the 1st INCF Workshop on Mouse and Rat Brain Digital Atlasing Systems (Boline et al., 2007, _Nature Preceedings_, doi:10.1038/npre.2007.1046.1) and includes a more detailed analysis of both the current state and desired state of digital atlasing along with specific recommendations for achieving these goals

    IAO-Intel: An Ontology of Information Artifacts in the Intelligence Domain

    Get PDF
    We describe on-going work on IAO-Intel, an information artifact ontology developed as part of a suite of ontologies designed to support the needs of the US Army intelligence community within the framework of the Distributed Common Ground System (DCGS-A). IAO-Intel provides a controlled, structured vocabulary for the consistent formulation of metadata about documents, images, emails and other carriers of information. It will provide a resource for uniform explication of the terms used in multiple existing military dictionaries, thesauri and metadata registries, thereby enhancing the degree to which the content formulated with their aid will be available to computational reasoning

    Security and privacy for web databases and services

    Abstract. A semantic web can be thought of as a web that is highly intelligent and sophisticated and one needs little or no human intervention to carry out tasks such as scheduling appointments, coordinating activities, searching for complex documents as well as integrating disparate databases and information systems. While much progress has been made toward developing such an intelligent web, there is still a lot to be done. For example, there is little work on security and privacy for the semantic web. However, before we examine security for the semantic web we need to ensure that its key components, such as web databases and services, are secure. This paper will mainly focus on security and privacy issues for web databases and services. Finally, some directions toward developing a secure semantic web will be provided

    Maintaining the integrity of XML signatures by using the manifest element

    One of the aims of providing 'security of data' in e-commerce transactions is making sure that the receiver receives the same data which the sender sends, that is the data has not been tampered in any way. To achieve this aim digital signatures are used. A digital signature helps in providing integrity, message authentication, and signer authentication for the signed data. An XML signature can contain or point to the data that is being signed. In this paper we discuss a possible solution of avoiding a signature from breaking when there is a change in the location of the document after it has been signed
