MPEG-SCORM : ontologia de metadados interoperáveis para integração de padrões multimídia e e-learning

Orientador: Yuzo IanoTese (doutorado) - Universidade Estadual de Campinas, Faculdade de Engenharia Elétrica e de ComputaçãoResumo: A convergência entre as mídias digitais propõe uma integração entre as TIC, focadas no domínio do multimídia (sob a responsabilidade do Moving Picture Experts Group, constituindo o subcomitê ISO / IEC JTC1 SC29), e as TICE, (TIC para a Educação, geridas pelo ISO / IEC JTC1 SC36), destacando-se os padrões MPEG, empregados na forma de conteúdo e metadados para o multimídia, e as TICE, aplicadas à Educação a Distância, ou e-Learning (o aprendizado eletrônico). Neste sentido, coloca-se a problemática de desenvolver uma correspondência interoperável de bases normativas, atingindo assim uma proposta inovadora na convergência entre as mídias digitais e as aplicações para e-Learning, essencialmente multimídia. Para este fim, propõe-se criar e aplicar uma ontologia de metadados interoperáveis para web, TV digital e extensões para dispositivos móveis, baseada na integração entre os padrões de metadados MPEG-21 e SCORM, empregando a linguagem XPathAbstract: The convergence of digital media offers an integration of the ICT, focused on telecommunications and multimedia domain (under responsibility of the Moving Picture Experts Group, ISO/IEC JTC1 SC29), with the ICTE (the ICT for Education, managed by the ISO/IEC JTC1 SC36), highlighting the MPEG formats, featured as content and as description metadata potentially applied to the Multimedia or Digital TV and as a technology applied to e-Learning. Regarding this, it is presented the problem of developing an interoperable matching for normative bases, achieving an innovative proposal in the convergence between digital Telecommunications and applications for e-Learning, both essentially multimedia. To achieve this purpose, it is proposed to creating a ontology for interoperability between educational applications in Digital TV environments and vice-versa, simultaneously facilitating the creation of learning metadata based objects for Digital TV programs as well as providing multimedia video content as learning objects for Distance Education. This ontology is designed as interoperable metadata for the Web, Digital TV and e-Learning, built on the integration between MPEG-21 and SCORM metadata standards, employing the XPath languageDoutoradoTelecomunicações e TelemáticaDoutor em Engenharia ElétricaCAPE

An Architecture for TV Content Distributed Search and Retrieval Using the MPEG Query Format (MPQF)

Traditional broadcasting of TV contents begins to coexist with new models of user aware content delivery. The definition of interoperable interfaces for precise content search and retrieval between the different involved parties is a requirement for the deployment of the new audiovisual distribution services. This paper presents the design of an architecture based on the MPEG Query Format (MPQF) for providing the necessary interoperability to deploy distributed audiovisual content search and retrieval networks between content producers, distributors, aggregators and consumer devices. A service-oriented architecture based on Web Services technology is defined. This paper also presents how the architecture can be applied to a real scenario, the XAC (Xarxa IP Audiovisual de Catalunya, Audiovisual IP Network of Catalonia). As far as we know, this is the first paper to apply MPQF to TV Content Distributed Search and Retrieval

Education alignment

This essay reviews recent developments in embedding data management and curation skills into information technology, library and information science, and research-based postgraduate courses in various national contexts. The essay also investigates means of joining up formal education with professional development training opportunities more coherently. The potential for using professional internships as a means of improving communication and understanding between disciplines is also explored. A key aim of this essay is to identify what level of complementarity is needed across various disciplines to most effectively and efficiently support the entire data curation lifecycle

Architecture of participation : the realization of the Semantic Web, and Internet OS

Thesis (S.M.)--Massachusetts Institute of Technology, System Design and Management Program, February 2008.Includes bibliographical references (p. 65-68).The Internet and World Wide Web (WWW) is becoming an integral part of our daily life and touching every part of the society around the world including both well-developed and developing countries. The simple technology and genuine intention of the original WWW, which is to help researchers share and exchange information and data across incompatible platforms and systems, have evolved into something larger and beyond what one could conceive. While WWW has reached the critical mass, many limitations are uncovered. To address the limitations, the development of its extension, the Semantic Web, has been underway for more than five years by the inventor of WWW, Tim Berners-Lee, and the technical community. Yet, no significant impact has been made. Its awareness by the public is surprisingly and unfortunately low. This thesis will review the development effort of the Semantic Web, examine its progress which appears lagging compared to WWW, and propose a promising business model to accelerate its adoption path.by Shelley Lau.S.M

BlogForever: D3.1 Preservation Strategy Report

This report describes preservation planning approaches and strategies recommended by the BlogForever project as a core component of a weblog repository design. More specifically, we start by discussing why we would want to preserve weblogs in the first place and what it is exactly that we are trying to preserve. We further present a review of past and present work and highlight why current practices in web archiving do not address the needs of weblog preservation adequately. We make three distinctive contributions in this volume: a) we propose transferable practical workflows for applying a combination of established metadata and repository standards in developing a weblog repository, b) we provide an automated approach to identifying significant properties of weblog content that uses the notion of communities and how this affects previous strategies, c) we propose a sustainability plan that draws upon community knowledge through innovative repository design

FLOSSTV Free, Libre, Open Source Software (FLOSS) within participatory 'TV hacking' Media and Arts Practices

This research operates in the context of a European political discourse, where the main concern is counter­cultural approaches to non­ mandatory collaboration and contractual agreements. FLOSSTV (Free, Libre, Open Source Software TV) covers a broad range of practices, from television via documentary up to media arts productions. This thesis documents the endeavour to formulate a policy for FLOSS culture. FLOSSTV studies the impact of new intellectual property legislation on media production, as well as conceptions and applications of collective authorship and alternative licensing schemes. FLOSSTV sets out to explore methods that can facilitate media and arts practitioners wishing to engage in collaborative media productions. The thesis sets out to investigate the theories and histories of collaborative media and arts productions in order to set the ground for an exploration of the tools, technologies and aesthetics of such collaborations. The FLOSSTV thesis proposes a set of contracts and policies that allow for such collaborations to develop. It is through practice that this research explores FLOSS culture, including its methods, licensing schemes and technologies. In order to focus the research within the field of FLOSSTV I initiated the practice ­based Deptford.TV pilot project as the central research experiment for the FLOSSTV thesis. DVD ONE contains a series of films produced collaboratively for Deptford.TV that express the characteristics and contractual arrangements of FLOSS culture. Deptford.TV is an online audiovisual database primarily collecting media assets around the Deptford area, in South­East London, UK. Deptford.TV functions as an open, collaborative platform that allows artists, film­makers, researchers and participants of the local workshops in and around Deptford, and also beyond Deptford, to store, share, re­edit and redistribute their footage and projects. The open and collaborative nature of the Deptford.TV project demonstrates a form of shared media practice in two ways: audiences become producers by submitting their own footage, and the database enables the contributors to interact with each other. Through my practice­lead research project Deptford.TV I argue that, by supporting collaborative methods and practices, FLOSS (Free, Libre, Open Source Software) can empower media and arts practitioners to collaborate in production and distribution processes of media and arts practices

Aligning National Approaches to Digital Preservation

The "Aligning National Approaches to Digital Preservation" (ANADP) conference was held at the National Library of Estonia, from May 23-25, 2011. More than 125 delegates from more than 20 countries were gathered in Tallinn, Estonia and explored how to create and sustain international collaborations to support the preservation of digital cultural memory. This publication contains a collection of peer-reviewed essays that were developed by conference panels and attendees in the months following ANADP

Managing long-term access to digital data objects: a metadata approach

As society becomes increasingly reliant on information technology for data exchange and long-term data storage the need for a system of data management to document and provide access to the 'societal memory' is becoming imperative. An examination of both the literature and current 'best Practice' underlines the absence to date of a proven universal conceptual basis to digital data preservation. The examination of differences in nature and sources of origin, between traditional 'print-based' and digital objects leads to a re-appraisal of current practices of data selection and preservation. The need to embrace past, present and future metadata developments in a rapidly changing environment is considered. Various hypotheses were formulated and supported regarding; the similarities and differences required in selection criteria for different types of Digital Data Objects (DDOs), the ability to define universal threshold standards for a framework of metadata for digital data preservation, and the role of selection criteria in such a framework. The research uses Soft Systems Methodology to investigate the potential of the metadata concept as the key to universal data management. Semi-structured interviews were conducted to explore the attitudes of information professionals in the United Kingdom towards the challenges facing information-dependent organisations attempting to preserve digital data over the long-term. In particular, the nature of DDOs being encountered by stakeholders, the reasons, policies, and procedures for preserving them, together with a range of specific issues such as; the role of metadata, access to, and rights management of DDOs. The societal need for selection to ensure efficient long-term access is considered. Drawing on - SSM modelling, this research develops a flexible, long-term management framework for digital data at a level higher than metadata, with selection as an essential component. The framework's conceptual feasibility has been examined from both financial and societal benefit perspectives, together with the recognition of constraints. The super-metadata framework provides a possible systematic approach to managing a wide range of digital data in a variety of formats, created/owned by a spectrum of information-dependent organisations
