Metadata Authority Description Schema (MADS): uma alternativa à utilização do formato MARC 21 para dados de autoridade

Introduction: Authority records interchange requires establishing and using metadata standards, such as MARC 21 Format for Authority Data, format used by several cataloging agencies, and Metadata Authority Description Schema (MADS), that has received little attention and it is a little widespread standard among agencies. Purpose: Presenting an introductory study about Metadata Authority Description Schema (MADS). Methodology: Descriptive and exploratory bibliographic research. Results: The paper address the MADS creation context, its goals and its structure and key issues related to conversion of records from MARC 21 to MADS. Conclusions: The study concludes that, despite its limitations, MADS might be used to create simple authority records in Web environment and beyond libraries context.

A conversão de registros na implantação de repositórios institucionais: o caso do Repositório Institucional UNESP

O Repositório Institucional UNESP foi criado em 2013 e, para sua implantação, foi povoado com dados obtidos de forma automática. Considerando a experiência realizada na UNESP, este trabalho tem por objetivo apresentar os processos utilizados para a conversão dos registros coletados de três diferentes fontes de dados (Web of Science, SciELO e Scopus) para inclusão no repositório. A partir da coleta dos registros, os padrões de metadados da Web of Science, da SciELO e da Scopus foram mapeados para o perfil de aplicação de metadados utilizado no repositório. Os registros foram coletados como arquivos XML e, para sua conversão, foram elaboradas folhas de estilo utilizando a linguagem XSLT. Após essa conversão, os arquivos XML foram convertidos em arquivos CSV e, então, importados no Repositório. Conclui-se que os processos de conversão utilizados permitiram alcançar as metas iniciais do Repositório e evitaram a necessidade de inclusão dos registros de forma manual.

Analytical Processing Over XML and XLink

Current commercial and academic OLAP tools do not process XML data that contains XLink. Aiming at overcoming this issue, this paper proposes an analytical system composed by LMDQL, an analytical query language. Also, the XLDM metamodel is given to model cubes of XML documents with XLink and to deal with syntactic, semantic and structural heterogeneities commonly found in XML documents. As current W3C query languages for navigating in XML documents do not support XLink, XLPath is discussed in this article to provide features for the LMDQL query processing. A prototype system enabling the analytical processing of XML documents that use XLink is also detailed. This prototype includes a driver, named sql2xquery, which performs the mapping of SQL queries into XQuery. To validate the proposed system, a case study and its performance evaluation are presented to analyze the impact of analytical processing over XML/XLink documents.

MARC 21 e XML como ferramentas para a consolidação da catalogação cooperativa automatizada: Uma revisão de literatura

The cooperation and the sharing of information cataloguing and bibliographical in environment automated, this was only possible with the creation and adoption of interchange format MARC21. But due to the progresses of the technologies of information and communication, of the crescent use of Internet and of the databases and databanks, there were the need of the creation and development of tools that optimize the organization activities, retrieval and interchange of information. XML is one of those developments that have as purpose to facilitate the management, storage and transmission of data through Internet. Before that, it was proposed through a literature revision, to analyze Interchange Format MARC21 and Markup Language XML as tools for the consolidation of the Automated Cooperative Cataloguing, your differences of storage flexibilities, organization, retrieval and interchange of data through Internet. This research made possible the divulgation to the community librarian, through a literature revision, that has been discussed internationally on MARC21 and XML

A Unified Framework for e-Commerce Systems Development : Business Process Pattern Perspective

In electronic commerce, systems development is based on two fundamental types of models, business models and process models. A business model is concerned with value exchanges among business partners, while a process model focuses on operational and procedural aspects of business communication. Thus, a business model defines the what in an e-commerce system, while a process model defines the how. Business process design can be facilitated and improved by a method for systematically moving from a business model to a process model. Such a method would provide support for traceability, evaluation of design alternatives, and seamless transition from analysis to realization. This work proposes a unified framework that can be used as a basis to analyze, to interpret and to understand different concepts associated at different stages in e-Commerce system development. In this thesis, we illustrate how UN/CEFACT’s recommended metamodels for business and process design can be analyzed, extended and then integrated for the final solutions based on the proposed unified framework. Also, as an application of the framework, we demonstrate how process-modeling tasks can be facilitated in e-Commerce system design. The proposed methodology, called BP3 stands for Business Process Patterns Perspective. The BP3 methodology uses a question-answer interface to capture different business requirements from the designers. It is based on pre-defined process patterns, and the final solution is generated by applying the captured business requirements by means of a set of production rules to complete the inter-process communication among these patterns.

Pattern-based segmentation of digital documents: model and implementation

This thesis proposes a new document model, according to which any document can be segmented in some independent components and transformed in a pattern-based projection, that only uses a very small set of objects and composition rules. The point is that such a normalized document expresses the same fundamental information of the original one, in a simple, clear and unambiguous way. The central part of my work consists of discussing that model, investigating how a digital document can be segmented, and how a segmented version can be used to implement advanced tools of conversion. I present seven patterns which are versatile enough to capture the most relevant documents’ structures, and whose minimality and rigour make that implementation possible. The abstract model is then instantiated into an actual markup language, called IML. IML is a general and extensible language, which basically adopts an XHTML syntax, able to capture a posteriori the only content of a digital document. It is compared with other languages and proposals, in order to clarify its role and objectives. Finally, I present some systems built upon these ideas. These applications are evaluated in terms of users’ advantages, workflow improvements and impact over the overall quality of the output. In particular, they cover heterogeneous content management processes: from web editing to collaboration (IsaWiki and WikiFactory), from e-learning (IsaLearning) to professional printing (IsaPress).

EXAM-S: an Analysis tool for Multi-Domain Policy Sets

As distributed collaborative applications and architectures are adopting policy based management for tasks such as access control, network security and data privacy, the management and consolidation of a large number of policies is becoming a crucial component of such policy based systems. In large-scale distributed collaborative applications like web services, there is the need of analyzing policy interactions and integrating policies. In this thesis, we propose and implement EXAM-S, a comprehensive environment for policy analysis and management, which can be used to perform a variety of functions such as policy property analyses, policy similarity analysis, policy integration etc. As part of this environment, we have proposed and implemented new techniques for the analysis of policies that rely on a deep study of state of the art techniques. Moreover, we propose an approach for solving heterogeneity problems that usually arise when considering the analysis of policies belonging to different domains. Our work focuses on analysis of access control policies written in the dialect of XACML (Extensible Access Control Markup Language). We consider XACML policies because XACML is a rich language which can represent many policies of interest to real world applications and is gaining widespread adoption in the industry.

Analisi di riferimenti bibliografici in documenti XML

Con il seguente elaborato propongo di presentare il lavoro svolto sui documenti XML che ci sono stati forniti. Più nello specifico, il lavoro è incentrato sui riferimenti bibliografici presenti in ogni documento e ha come fine l'elaborazione delle informazioni estrapolate al fine di poterle esportare nel formato RDF (Resource Description Framework). I documenti XML (eXtensible Markup Language) fornitimi provengono dalla casa editrice Elsevier, una delle più grandi case editrici di articoli scientifici organizzati in riviste specializzate (journal).

Searching and retrieving in content-based repositories of formal mathematical knowledge

In this thesis, the author presents a query language for an RDF (Resource Description Framework) database and discusses its applications in the context of the HELM project (the Hypertextual Electronic Library of Mathematics). This language aims at meeting the main requirements coming from the RDF community. in particular it includes: a human readable textual syntax and a machine-processable XML (Extensible Markup Language) syntax both for queries and for query results, a rigorously exposed formal semantics, a graph-oriented RDF data access model capable of exploring an entire RDF graph (including both RDF Models and RDF Schemata), a full set of Boolean operators to compose the query constraints, fully customizable and highly structured query results having a 4-dimensional geometry, some constructions taken from ordinary programming languages that simplify the formulation of complex queries. The HELM project aims at integrating the modern tools for the automation of formal reasoning with the most recent electronic publishing technologies, in order create and maintain a hypertextual, distributed virtual library of formal mathematical knowledge. In the spirit of the Semantic Web, the documents of this library include RDF metadata describing their structure and content in a machine-understandable form. Using the author's query engine, HELM exploits this information to implement some functionalities allowing the interactive and automatic retrieval of documents on the basis of content-aware requests that take into account the mathematical nature of these documents.

The Design of XML-Based Model and Experiment Description Languages for Network Simulation

The Simulation Automation Framework for Experiments (SAFE) is a project created to raise the level of abstraction in network simulation tools and thereby address issues that undermine credibility. SAFE incorporates best practices in network simulationto automate the experimental process and to guide users in the development of sound scientific studies using the popular ns-3 network simulator. My contributions to the SAFE project: the design of two XML-based languages called NEDL (ns-3 Experiment Description Language) and NSTL (ns-3 Script Templating Language), which facilitate the description of experiments and network simulationmodels, respectively. The languages provide a foundation for the construction of better interfaces between the user and the ns-3 simulator. They also provide input to a mechanism which automates the execution of network simulation experiments. Additionally,this thesis demonstrates that one can develop tools to generate ns-3 scripts in Python or C++ automatically from NSTL model descriptions.

Statistical Analyses and Reproducible Research

For various reasons, it is important, if not essential, to integrate the computations and code used in data analyses, methodological descriptions, simulations, etc. with the documents that describe and rely on them. This integration allows readers to both verify and adapt the statements in the documents. Authors can easily reproduce them in the future, and they can present the document's contents in a different medium, e.g. with interactive controls. This paper describes a software framework for authoring and distributing these integrated, dynamic documents that contain text, code, data, and any auxiliary content needed to recreate the computations. The documents are dynamic in that the contents, including figures, tables, etc., can be recalculated each time a view of the document is generated. Our model treats a dynamic document as a master or ``source'' document from which one can generate different views in the form of traditional, derived documents for different audiences. We introduce the concept of a compendium as both a container for the different elements that make up the document and its computations (i.e. text, code, data, ...), and as a means for distributing, managing and updating the collection. The step from disseminating analyses via a compendium to reproducible research is a small one. By reproducible research, we mean research papers with accompanying software tools that allow the reader to directly reproduce the results and employ the methods that are presented in the research paper. Some of the issues involved in paradigms for the production, distribution and use of such reproducible research are discussed.
