Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Pós-graduação em Ciência da Informação - FFC; The contemporary society characterized as information society or net society is closely related to the use of information and communication technologies (ICT), especially the World Wide Web, which makes possible the creation of contents and the information access with no boundaries of time and space. We can see the increase of people using this technology, since its creation in the beginning of 1990 decade, and we can highlight the elderly users. These users find in the Web an environment in which they can develop different activities, as easily dealing with daily duties and getting information about subjects related to aging, among others. However, we verify that the Web information environments do not have an Information Architecture developed with the specific necessities of this public, making difficult the use and access, and then, making hard the digital and social inclusion of this users group. In this context, our objective is to identify elements that enable the social and digital inclusion of the elderly using the study of Information Architecture...

In 2006 the Portuguese National Archives (Directorate General of the Portuguese Archives) engaged in the development of an OAIS compatible digital repository system for long-term preservation of digital material. Simultaneously, at the University of Minho a project called CRiB was being devised which aimed at the development of a wholesome set of services to aid digital preservation. Among those services were format converters, quality-assessment tools, preservation planning and automatic metadata production for retaining representations’ authenticity. This paper provides a detailed description of both projects and discusses how these may be integrated into a complete digital preservation solution based on currently available archiving and preservation standards, e.g. OAIS, EAD, PREMIS, METS and ANSI/NISO Z39.87.

Comunicação apresentada na "Digital Preservation Summit 2011", Hamburg, Germany, 19 a 20 October 2011.; In mid 2006, the Portuguese National Archives (Directorate-General of the Portuguese Archives) launched a project called RODA (Repository of Authentic Digital Objects) aiming at identifying and bringing together all the necessary technology, human resources and political support to carry out long-term preservation of digital materials being produced by the Portuguese public administration. As part of the original goals of RODA was the development of a digital repository capable of ingesting, managing and providing access to the various types of digital objects produced by national public institutions. The development of such repository should be supported by open-source technologies and, as much as possible, be based on existing standards such as the OAIS, METS, EAD and PREMIS. The end result of the project is a full-fledge repository that supports integration of preservation action tasks and with an architecture allows a continuous adaptation of new functionality and technologies. It defines a data model that suites all meta information requisites of a digital preservation repository and a complex ingest workflow that validates and adapts all information to this curation environment.; European Union under FP7 ICT-2009.4.1

Mestrado em Estudos de Informação e Bibliotecas Digitais; Este trabalho analisa o processo de construção do repositório digital Objectos do culto católico. A constituição de uma colecção de temática religiosa justifica-se pelo facto de ser um conjunto coerente e representativo de uma parte significativa dos acervos nacionais de património cultural móvel. Por outro lado, a variedade de tipologias permite enquadrar o actual conceito de biblioteca digital, como um repositório alargado de conteúdos, integrando espécies bibliográficas e objectos museológicos. Estudámos as características das imagens digitalizadas adequadas à constituição de uma matriz de arquivo, a partir das quais se elaboram cópias de consulta, e descrevemos um esquema de nomeação e organização dos ficheiros digitais obtidos. Analisámos os esquemas de metadados a aplicar no âmbito dos objectos patrimoniais, de modo a garantir a leitura e a recuperação da informação a longo prazo. No contexto deste trabalho, inventariámos e processámos, segundo as regras de digitalização, metacodificação e preservação digital, compiladas e descritas nesta dissertação, 10 objectos patrimoniais de tipologia variada (pintura, ourivesaria...

The DSpace™ digital repository system was released as open source software in November of 2002. In the year since then it has been adopted by a large number of research universities and other organizations world-wide that need a digital repository solution for a number of content types: research articles, gray literature, e-theses, cultural materials, scientific datasets, institutional records, educational materials, and more. The DSpace platform and its various applications are becoming better understood with experience and time. As one result of a recent meeting of the DSpace user community, we are now venturing into the territory of broad, community-based open source development and management, and gaining insights from the experience of the Apache Foundation, Global Grid Forum, and other successful open source projects about how to build open source software for the digital library domain.

In this paper we describe DSpace™, an open source system that acts as a repository for digital research and educational material produced by an organization or institution. DSpace was developed during two years’ collaboration between the Hewlett-Packard Company and MIT Libraries. The development team worked closely with MIT Libraries staff and early adopter faculty members to produce a ‘breadth-first’ system, providing all of the basic features required by a digital repository service. As well as functioning as a live service, DSpace is intended as a base for extending repository functionality, particularly to address long-term preservation concerns. We describe the functionality of the current DSpace system, and briefly describe its technical architecture. We conclude with some remarks about the future development and operation of the DSpace system.

The MIT Libraries, the San Diego Supercomputer Center, and the University of California San Diego Libraries are conducting the PLEDGE Project to determine the set of policies that affect operational digital preservation archives and to develop standardized means of recording and enforcing them using rules engines. This has the potential to allow for automated assessment of "trustworthiness" of digital preservation archives. We are also evaluating the completeness of other efforts to define policies for digital preservation such as the RLG/NARA Trusted Digital Repository checklist and the PREMIS metadata schema. We present our results to date.; National Archives and Records Administration (US) under NSF cooperative agreement 0523307 through a supplement to SCI 0438741 and the NSF grant ITR 0427196.

The RLG/NARA trusted digital repository (TDR) certification checklist defines a set of assessment criteria for preservation environments. The criteria can be mapped into data management policies that define how a digital preservation environment is operated. We explore how the enforcement of these management policies can be automated through their characterization as rules that control preservation services. By integrating a rule-based data management system with the DSpace digital archive system, we expect to demonstrate automated audits of the TDR checklist for a defined set of local policies. The system is sufficiently general that one can also demonstrate the completeness and self-consistency of preservation environments. This is the concept that all required preservation metadata are controlled by management policies, and that for each management policy the required preservation metadata are preserved.; National Archives and Records Administration under NSF cooperative agreement 0523307 through a supplement to SCI 0438741, "Cyberinfrastructure; From Vision to Reality"

This document records the process of migrating eprints.org data to a Fez repository. Fez is a Web-based digital repository and workflow management system based on Fedora (http://www.fedora.info/). At the time of migration, the University of Queensland Library was using EPrints 2.2.1 [pepper] for its ePrintsUQ repository. Once we began to develop Fez, we did not upgrade to later versions of eprints.org software since we knew we would be migrating data from ePrintsUQ to the Fez-based UQ eSpace. Since this document records our experiences of migration from an earlier version of eprints.org, anyone seeking to migrate eprints.org data into a Fez repository might encounter some small differences. Moving UQ publication data from an eprints.org repository into a Fez repository (hereafter called UQ eSpace (http://espace.uq.edu.au/) was part of a plan to integrate metadata (and, in some cases, full texts) about all UQ research outputs, including theses, images, multimedia and datasets, in a single repository. This tied in with the plan to identify and capture the research output of a single institution, the main task of the eScholarshipUQ testbed for the Australian Partnership for Sustainable Repositories project (http://www.apsr.edu.au/). The migration could not occur at UQ until the functionality in Fez was at least equal to that of the existing ePrintsUQ repository. Accordingly...

Generally, when we think of a digital collection or repository, we think of digital images, ebooks, audio and video files. But some important digital collections, such a bibliographies, don’t have content per se but consist of metadata describing a physical object such as a book, a digital object such as an audio recording or an event such as an opera performance. Not surprisingly, this kind of “contentless” digital object is dependent on metadata to describe it. And while we have standards for bibliographic entries in books and articles, we need more complex metadata for digital bibliographic entries. For the past several months, the Library Technology Software Development group has been working on exactly how to represent these contentless digital objects in our Fedora digital repository using the Hydra based software development environment. Using The Televised Opera and Musical Comedy Database as a sample, we will discuss the work we have done to create a general bibliographic tool for the Fedora Digital Repository.

A growing proportion of an institution's output and assets is digital in format (eg, data sets, documents, multimedia objects). Digital repositories are becoming a critical part of an institution's information infrastructure to ensure the preservation and ongoing access to these digital objects. Over and above a mere software system, the digital repository represents the institution's responsibility for the long term stewardship of its digital assets. The workshops will provide a general background to digital repositories as well as a practical walk-through of a particular repository system. The workshops will also cover the essential issues involved in establishing a repository service, including: - Planning and management of a repository service - Involving your community - Criteria for choosing repository software - Spectrum of services - Sustainability guidelines and issues - Case study demonstrations; Australian Partnership for Sustainable Repositories (APSR); APSR is running a series of workshops on "Establishing a Digital Repository Service". These workshops are for the benefit of institutions who are setting up digital repository services or thinking about such. The events will also provide an opportunity to meet and build networks with interested people in your region. The half-day workshops will run in various locations around Australia (Canberra...

By mid 2006, all Australian universities had established, or were partway to establishing, institutional repository services. The development of institutional repository services can often be related to the open access movement, which seeks to make valued research outputs openly available by encouraging academics to place their publications into repositories, enhancing their availability and bypassing the high cost of journal subscriptions. However, many universities have extended the functionality of their repository services for other purposes, such as giving scholars the opportunity to develop their own research portfolio, providing a means of improving research reporting, establishing an electronic publishing service, or giving access to collections of images or other research outputs. The potential for development seems endless. At the same time, university research increasingly involves the use, generation, manipulation, sharing and analysis of digital resources. The importance of what is generally called "eResearch" on the national agenda shows the need for improved data management and sustainability practices to support research over the longer term. This raises questions of the relationship between the repository and eResearch and provides challenges to repository managers to broaden their thinking still further to help meet these needs. The Australian Partnership for Sustainable Repositories (APSR) was established in early 2004 with a focus on issues of access continuity and the sustainability of digital collections. In mid-2006...

The purpose of the NIST Digital Repository of Mathematical Formulae (DRMF) is to create a digital compendium of mathematical formulae for orthogonal polynomials and special functions (OPSF) and of associated mathematical data. The DRMF addresses needs of working mathematicians, physicists and engineers: providing a platform for publication and interaction with OPSF formulae on the web. Using MediaWiki extensions and other existing technology (such as software and macro collections developed for the NIST Digital Library of Mathematical Functions), the DRMF acts as an interactive web domain for OPSF formulae. Whereas Wikipedia and other web authoring tools manifest notions or descriptions as first class objects, the DRMF does that with mathematical formulae.
