“…Managing and applying some forms of control on access and, especially, re-use conditions in heterogeneous contexts as those generalist repositories are confronting with is one of the most relevant yet unsolved issues. Despite few languages to specify rights exist, e.g., MPEG-21 REL (Wang et al, 2005) and Open Digital Rights Language (Iannella, 2002) (Abelson et al, 2008). Another important aspect that strongly influences the possibility of effectively reusing published dataset, which has not yet received enough attention, is "compatibility" between the licenses of the dataset and the licences of the rest of material "associated" with the dataset, including its documentation.…”

Research data publishing is intended as the release of research data to make it possible for practitioners to (re)use them according to "open science" dynamics. There are three main actors called to deal with research data publishing practices: researchers, publishers, and data repositories. This study analyses the solutions offered by generalist scientific data repositories, i.e., repositories supporting the deposition of any type of research data. These repositories cannot make any assumption on the application domain. They are actually called to face with the almost open ended typologies of data used in science. The current practices promoted by such repositories are analysed with respect to eight key aspects of data publishing, i.e., dataset formatting, documentation, licensing, publication costs, validation, availability, discovery and access, and citation. From this analysis it emerges that these repositories implement well consolidated practices and pragmatic solutions for literature repositories. These practices and solutions can not totally meet the needs of management and use of datasets resources, especially in a context where rapid technological changes continuously open new exploitation prospects.

“…MPEG-21 [35] is a framework that offers support for multimedia delivery and consumption, simplifying transactions and ensuring content interoperability. It defines many content/consumption related issues, like unique identification, rights and permissions through a specific language (Rights Expression Language) [81], etc. A fundamental piece of this framework is the Digital Item, which is a basic unit of reusable content representation, and is declared in the Digital Item Declaration (DID) [14].…”

“…However, none of these standards expanded their view to consider a broader outlook, which will require much more functionalities to support this content exchange. Beyond content packaging and deployment, some initiatives address additional requirements: OAIS considers the content storage, RAS defines a version id creation policy to their manifests (but does not address the version control and management infrastructure) and the MPEG-21 group defines an XML language to express rights and permissions (Rights Expression Language) that uses terms defined in a Rights Data Dictionary [81], which is based on the XrML -eXtensible rights Markup Language [82]. Our Fluid Web approach, on the other hand, expanded the perspective from a content artifact that is deployed through the Web to a complete infrastructure to support collaborative work.…”

ResumoA Web está evoluindo de um espaço para publicação/consumo de documentos para um ambiente para trabalho colaborativo, onde o conteúdo digital pode viajar e ser replicado, adaptado, decomposto, fundido e transformado. Designamos esta perspectiva por Fluid Web. Esta visão requer uma reformulação geral da abordagem típica orientada a documentos que permeia o gerenciamento de conteúdo na Web. Esta tese apresenta nossa solução para a Fluid Web, que permite nos deslocarmos de uma perspectiva orientada a documentos para outra orientada a conteúdo, onde "conteúdo" pode ser qualquer objeto digital. A solução é baseada em dois eixos: (i) uma unidade auto-descritiva que encapsula qualquer tipo de artefato de conteúdo -o Componente de Conteúdo Digital (Digital Content Component -DCC); e (ii) uma infraestrutura para a Fluid Web que permite o gerenciamento e distribuição de DCCs na Web, cujo objetivo é dar suporte à colaboração na Web.Concebidos para serem reusados e adaptados, os DCCs encapsulam dados e software usando uma única estrutura, permitindo deste modo composição homogênea e processamento de qualquer conteúdo digital, seja este executável ou não. Estas propriedades são exploradas pela nossa infraestrutura para a Fluid Web, que engloba mecanismos de descoberta e de anotação de DCCs em múltiplos níveis, gerenciamento de configurações e controle de versões. Nosso trabalho explora padrões de Web Semântica e ontologias taxonômicas, que servem como uma ponte semântica, unificando vocabulários para gerenciamento de DCCs e facilitando as tarefas de descrição/indexação/descoberta de conteúdo. Os DCCs e sua infraestrura foram implementados e são ilustrados por meio de exemplos práticos, para aplicações científicas.As principais contribuições desta tese são: o modelo de Digital Content Component; o projeto da infraestrutura para a Fluid Web baseada em DCCs, com suporte para armazenamento baseado em repositórios, compartilhamento, controle de versões e gerenciamento de configurações distribuídas; um algoritmo para a descoberta de conteúdo digital que explora a semântica associada aos DCCs; e a validação prática dos principais conceitos desta pesquisa, com a implementação de protótipos. vii
