Open Journal Systems

Os editores de periódicos científicos adotam frequentemente, no Brasil, o Open Journal Systems (OJS) por se tratar de um software livre que possibilita criar, com autonomia, um ambiente de produção, armazenamento e acesso à informação. Porém, essa editoração de caráter científico, associada à demanda por maior produtividade acadêmica, nem sempre foi acompanhada de processos de salvaguarda e de institucionalização da memória relacionada ao conteúdo publicado. A preservação digital de periódicos científicos, na área de Humanidades, está contemplada na iniciativa da Rede Cariniana do IBICT / MCTI, que integra múltiplos agentes em uma rede distribuída, no modelo da Aliança LOCKSS da Stanford University. Essa solução, que articula processos conjuntos de guarda e preservação por longo prazo, implica a eleição de serviços tecnológicos de baixo custo, a adoção de políticas de memória de cada instituição envolvida e o reconhecimento das responsabilidades sobre a preservação do patrimônio científico do país. Esse tipo de preservação distingue-se das formas isoladas de arquivamento e conservação de documentos em instituições de memória. A emergência de sistemas em rede para a preservação documental, diante da dominância das tecnologias digitais, integra agentes institucionais, seus registros e distintas políticas memoriais na gestão de longo prazo da informação científica.         AbstractScientific journal editors in Brazil frequently adopt the Open Journal Systems (OJS) because it is a free software that enables to create, independently, a production environment, storage and access to information. However, this scientific publishing, combined with demand for higher academic productivity, has not always been followed by safeguard procedures and institutionalization of memory related to the published content. Digital preservation of scientific journals in the Humanities is provided by the Cariniana Network, an initiative of IBICT / MCTI that integrates multiple agents in a distributed network, based on the pattern created by the LOCKSS Alliance of Stanford University. This solution regarding digital objects, combining guard sets processes and preservation in the long run, implies the election of inexpensive technological services, the adoption of storage policies of each institution involved and the recognition that the responsibilities for the preservation of the scientific heritage of the country are distinguished from isolated forms of archiving and conservation of documents in memory institutions.The emergence of networked systems for document preservation, given the dominance of digital technologies, integrates institutional agents, their records and memorials distinct policies in the long-term management of scientific information.Keywords: Electronic Journals; Digital Preservation; Cariniana Network; Electronic Edition; Scientific Heritage.

This article introduces the National Library of Australia’s Digital Preservation Knowledge Base which helps the Library to manage digital objects from its collections over the long term. The Knowledge Base includes information on file formats, rendering software, operating systems, hardware and, most importantly, the relationships between them. Most of the work on the Knowledge Base over the last few years has been focused on the mapping of functional relationships between file formats, their versions and software applications. The information is gathered through unique empirical research and is initially being recorded in a multiple-worksheet Excel file in a semi-structured format, though development of a prototype graph database is underway.

To preserve digitally encoded information over a long term following the OAIS Reference Model requires that the information remains accessible, understandable and usable by a specified Designated Community. These are significant challenges for repositories. It will be argued that infrastructure which is needed to support this preservation must be seen in the context of the broader science data infrastructure which international and national funders seek to put in place. Moreover aspects of the preservation components of this infrastructure must themselves be preservable, resulting in a recursive system which must also be highly adaptable, loosely coupled and asynchronous. Even more difficult is to be able to judge whether any proposal is actually likely to be effective. From the earliest discussions of concerns about the preservability of digital objects there have been calls for some way of judging the quality of digital repositories. In this chapter several interrelated efforts which contribute to solutions for these issues will be outlined. Evidence about the challenges which must be overcome and the consistency of demands across nations, disciplines and organisations will be presented, based on extensive surveys which have been carried out by the PARSE.Insight project (http://www.parse-insight.eu). The key points about the revision of the OAIS Reference Model which is underway will be provided; OAIS provides many of the key concepts which underpin the efforts to judge solutions. In the past few years the Trustworthy Repositories Audit and Certification: Criteria and Checklist (TRAC) document has been produced, as well as a number of related checklists. These efforts provide the background of the international effort (the RAC Working Group http://wiki.digitalrepositoryauditandcertification.org) to produce a full ISO standard on which an accreditation and certification process can be built. If successful this standard and associated processes will allow funders to have an independent evaluation of the effectiveness of the archives they support and data producers to have a basis for deciding which repository to entrust with their valuable data. It could shape the digital preservation market. The CASPAR project (http://www.casparpreserves.eu) is an EU part funded project with total spend of 16MEuros which is trying to faithfully implement almost all aspects of the OAIS Reference Model in particular the Information Model. The latter involves tools for capturing all types of Representation Information (Structure, Semantics and all Other types), and tools for defining the Designated Community. This chapter will describe implementations of tools and infrastructure components to support repositories in their task of long term preservation of digital resources, including the capture and preservation of digital rights management and evidence of authenticity associated with digital objects. In order to justify their existence, most repositories must also support contemporaneous use of contemporary as well as “historical” resources; the authors will show how the same techniques can support both, and hence link to the fuller science data infrastructure.

The problem of developing solutions required for the preservation of and provision of continued access to digital information is one that is faced by public sector, commercial organizations and private individuals. There is a need to join national and international activities of expert consortiums, associations and networks that initiate necessary activities and approach, coordinate them and present results to all variety of stakeholders. Community-wide coordination will facilitate pooling of the expertise that exists across the academic, research, cultural, public administration and industry sectors in Europe.The authors present objectives and goals of the project, partner organisations, interaction with other projects and initiatives, first results of the project, namely creation and dissemination of DPE research roadmap in order to deliver a vision of digital preservation and curation, development of the DPE community that should cluster different types of partners, both individual and institutions, to create a framework of members. Faculty of Communication (Vilnius University) is responsible for development of a common training framework providing for a wide pool of practical skills and expertise in digital preservation, while allowing meeting local requirements. Creation of training materials and establishing of a data base of qualified trainers will lead to a certificate in Digital Preservation in future. This activity is based on the “Outline of training principles and objectives”. This deliverable presents structured survey of the area of digital preservation, in particular as regards topics of training and education.Digital preservation, curation and permanent Access are notions that convey commitment to warrant longterm access to digital materials. It means a need for long-term investments that will only pay dividends in long run. In this context DPE has to raise public awareness of digital preservation and its value. DPE’s success will help to secure a shared knowledge base of the processes, synergy of activity, systems and techniques needed for the long-term management of digital objects.

Digital preservation is a research area devoted to keeping digital assets preserved and usable for many years. Out of the many approaches to digital preservation, the present research article follows a new object-centered digital preservation paradigm where digital objects share part of the responsibility for preservation: they can move, replicate, and evolve to a higher-quality format inside a digital ecosystem. In the new framework, the behavior of digital objects needs to be modeled in order to obtain the best preservation strategy. Thus, digital objects are programmed with the mission of their own long-term self-preservation, which entails being accessible and reproducible by users at any time in the future regardless of frequent technological changes due to software and hardware upgrades. Three nature-inspired computational intelligence algorithms, based on the collective behavior of decentralized and self-organized systems, were selected for the modeling approach: multipopulation genetic algorithm, ant colony optimization, and a virus-based algorithm. TiM, a simulated environment for running distributed digital ecosystems, was used to perform the experiments. The results map the relation between the models and the expected object diversity obtained in short- and mid-term digital preservation scenarios. Comparing the results, the best performance corresponded to the multipopulation genetic algorithm. The article aims to be a first step in the digital self-preservation field. Building nature-inspired model behaviors is a good approach and opens the door to future tests with other AI-based methods.

Term Data

Public entities or institutions that have the responsibility of keeping long-term data, base their processes on digital preservation, involving the application of information technology and activities in the field of information sciences. The digital preservation has historical implications, it has a direct effect on the cultural heritage, because, without information (digital or not) that is guarded, there is no inheritance or culture, but without technology that allows the preservation or recovery of such information, neither would it be, Thus, the research question is posed as: What technical and legal characteristics are necessary to have an adaptive digital preservation model based on aspects of digital object management and organizational infrastructure, to ensure accessibility of information in the long term in public institutions of Ecuador ?, determining through an evaluation of NESTOR trust repositories and Ecuadorian legislation, that it is necessary to create an adaptive digital Preservation model.

Long Term Preservation

The digital preservation community currently utilises a number of tools and automated processes to identify and validate digital objects. The identification of digital objects is a vital first step in their long-term preservation, but the results returned by tools used for this purpose are lacking in transparency, and are not easily tested or verified. This paper suggests that a test corpus of digital objects is one way of providing this verification and validation, ultimately improving trust in the tools, and providing further stimulus to their development. Issues to be considered are outlined, and attention is drawn to particular examples of existing digital corpora which could conceivably provide a useable framework or starting point for our own communities needs. This paper does not seek to answer all questions in this area, but merely attempts to set out areas for consideration in any next step that is taken.

Effective digital preservation depends on a set of preservation services that work together to ensure that digital objects can be preserved for the long-term. These services need digital preservation metadata, in particular, descriptions of the properties that digital objects may have and descriptions of the requirements that guide digital preservation services. This paper analyzes how these services interact and use these metadata and develops a data dictionary to support them.

Purpose The purpose of this study is to investigate the concept of digital preservation and traditional preservation per se and discusses various issues related to long-term preservation in a digital environment. Design/methodology/approach The study attempts to look into the various aspects of preservation in context of digital objects (borne or digitalized) especially. Bundling of an object (digital), digital storage, quality control and risk preparedness are some of the pointers studied to perceive an overall scenario for long-term preservation of an object. Findings Various methods have been suggested to deal with the issues related to long-term preservation of an object which can be used to frame an organization’s policy for long-term preservation. Originality/value The study emphasizes on collective measures incorporating traditional and digital means to ensure long-term preservation. It lists down various checklists to deal with various issues pertinent to long-term digital preservation.
