Applying Open Storage to Institutional Repositories
No full textRepository interoperability and the capability to support preservation can be enhanced by introducing a storage layer that is independent of repository software. Institutional Repositories (IRs) are largely characterized by ‘openness’, that is, most are based on open source software, conform with the Open Archives Initiative (OAI) and aim to provide open access to content and data. We introduce a new ‘open’ approach to repositories: open storage combines open source software with standard hardware storage architectures. Examples include platforms provided by Sun Microsystems, which we use in this work. The paper will describe how the open storage approach has been allied to the OAI framework for Object Reuse and Exchange (ORE) to enable repositories managed with different softwares to share and copy data more easily and to be provided with extra services such as preservation service
Towards smart storage for repository preservation services
No full textThe move to digital is being accompanied by a huge rise in volumes of (born-digital) content and data. As a result the curation lifecycle has to be redrawn. Processes such as selection and evaluation for preservation have to be driven by automation. Manual processes will not scale, and the traditional signifiers and selection criteria in older formats, such as print publication, are changing. The paper will examine at a conceptual and practical level how preservation intelligence can be built into software-based digital preservation tools and services on the Web and across the network ‘cloud’ to create ‘smart’ storage for long-term, continuous data monitoring and management. Some early examples will be presented, focussing on storage management and format risk assessment
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Using OAI-ORE to Transform Digital Repositories into Interoperable Storage and Services Applications
Full text linkIn the digital age libraries are required to manage large numbers of diverse objects. One advantage of digital objects over fixed physical objects is the flexibility of ‘binding’ them into publications or other useful aggregated intellectual entities while retaining the ability to reuse them independently in other contexts. An emerging framework for managing flexible aggregations of digital objects is provided by the Open Archives Initiative (OAI) with its work on Object Reuse and Exchange (ORE). This paper will show how OAI-ORE is being used to manage content in digital repositories, in particular institutional repositories, and has the potential ultimately to transform the conception of digital repositories
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
