XML storage and retrieval using the semantic binary object -oriented database system (SEM-ODB)

Over the past five years, XML has been embraced by both the research and industrial community due to its promising prospects as a new data representation and exchange format on the Internet. The widespread popularity of XML creates an increasing need to store XML data in persistent storage systems and to enable sophisticated XML queries over the data. The currently available approaches to addressing the XML storage and retrieval issue have the limitations of either being not mature enough (e.g. native approaches) or causing inflexibility, a lot of fragmentation and excessive join operations (e.g. non-native approaches such as the relational database approach). ^ In this dissertation, I studied the issue of storing and retrieving XML data using the Semantic Binary Object-Oriented Database System (Sem-ODB) to leverage the advanced Sem-ODB technology with the emerging XML data model. First, a meta-schema based approach was implemented to address the data model mismatch issue that is inherent in the non-native approaches. The meta-schema based approach captures the meta-data of both Document Type Definitions (DTDs) and Sem-ODB Semantic Schemas, thus enables a dynamic and flexible mapping scheme. Second, a formal framework was presented to ensure precise and concise mappings. In this framework, both schemas and the conversions between them are formally defined and described. Third, after major features of an XML query language, XQuery, were analyzed, a high-level XQuery to Semantic SQL (Sem-SQL) query translation scheme was described. This translation scheme takes advantage of the navigation-oriented query paradigm of the Sem-SQL, thus avoids the excessive join problem of relational approaches. Finally, the modeling capability of the Semantic Binary Object-Oriented Data Model (Sem-ODM) was explored from the perspective of conceptually modeling an XML Schema using a Semantic Schema. ^ It was revealed that the advanced features of the Sem-ODB, such as multi-valued attributes, surrogates, the navigation-oriented query paradigm, among others, are indeed beneficial in coping with the XML storage and retrieval issue using a non-XML approach. Furthermore, extensions to the Sem-ODB to make it work more effectively with XML data were also proposed. ^

Creating Structured PDF Files Using XML Templates

This paper describes a tool for recombining the logical structure from an XML document with the typeset appearance of the corresponding PDF document. The tool uses the XML representation as a template for the insertion of the logical structure into the existing PDF document, thereby creating a Structured/Tagged PDF. The addition of logical structure adds value to the PDF in three ways: the accessibility is improved (PDF screen readers for visually impaired users perform better), media options are enhanced (the ability to reflow PDF documents, using structure as a guide, makes PDF viable for use on hand-held devices) and the re-usability of the PDF documents benefits greatly from the presence of an XML-like structure tree to guide the process of text retrieval in reading order (e.g. when interfacing to XML applications and databases).

Mapping and Displaying Structural Transformations between XML and PDF

Documents are often marked up in XML-based tagsets to delineate major structural components such as headings, paragraphs, figure captions and so on, without much regard to their eventual displayed appearance. And yet these same abstract documents, after many transformations and 'typesetting' processes, often emerge in the popular format of Adobe PDF, either for dissemination or archiving. Until recently PDF has been a totally display-based document representation, relying on the underlying PostScript semantics of PDF. Early versions of PDF had no mechanism for retaining any form of abstract document structure but recent releases have now introduced an internal structure tree to create the so called 'Tagged PDF'. This paper describes the development of a plugin for Adobe Acrobat which creates a two-window display. In one window is shown an XML document original and in the other its Tagged PDF counterpart is seen, with an internal structure tree that, in some sense, matches the one seen in XML. If a component is highlighted in either window then the corresponding structured item, with any attendant text, is also highlighted in the other window. Important applications of correctly Tagged PDF include making PDF documents reflow intelligently on small screen devices and enabling them to be read out in correct reading order, via speech synthesiser software, for the visually impaired. By tracing structure transformation from source document to destination one can implement the repair of damaged PDF structure or the adaptation of an existing structure tree to an incrementally updated document.

Enhancing composite Digital Documents Using XML-based Standoff Markup

Document representations can rapidly become unwieldy if they try to encapsulate all possible document properties, ranging from abstract structure to detailed rendering and layout. We present a composite document approach wherein an XMLbased document representation is linked via a shadow tree of bi-directional pointers to a PDF representation of the same document. Using a two-window viewer any material selected in the PDF can be related back to the corresponding material in the XML, and vice versa. In this way the treatment of specialist material such as mathematics, music or chemistry (e.g. via read aloud or play aloud ) can be activated via standard tools working within the XML representation, rather than requiring that application-specific structures be embedded in the PDF itself. The problems of textual recognition and tree pattern matching between the two representations are discussed in detail. Comparisons are drawn between our use of a shadow tree of pointers to map between document representations and the use of a code-replacement shadow tree in technologies such as XBL.

Implementação de um modelo baseado em XML para suporte da dinâmica processual de negócio

Este artigo descreve um modelo para implementação de plataformas dinâmicas de negócio, exclusivamente baseadas em tecnologias XML. Apresenta um caso real que implementa as suas diversas camadas, apresentação, lógica e dados, em XML. A comunicação entre camadas é assegurada por serviços Web (WS), tornando esta arquitectura orientada aos serviços (SOA). O modelo proposto sustenta toda a programação do processo de negócio numa linguagem de alto nível, o WS-BPEL, proporcionando, desse modo, condições de adaptação ao dinamismo exigido pelo negócio da organização e à heterogeneidade dos sistemas. O caso real é de uma secretaria electrónica que surge no contexto dos portais Web universitários. O sistema desenvolvido visa oferecer um conjunto de serviços para acesso a informação e para o despoletar de acções computacionais e/ou humanas.

XMLScore: Representación gráfica y reproducción de partituras musicales en formato XML

MusicXML es quizá el más conocido de los formatos de notación musical basados en XML. Se trata de un formato abierto que a día de hoy utilizan multitud de programas musicales. El presente proyecto consiste en desarrollar una aplicación informática que, dada una partitura en formato MusicXML, sea capaz de realizar dos tareas: 1. Generar automáticamente una imagen (bmp, jpg, ...) con la representación gráfica de la partitura y la muestre por pantalla. 2. Reproducir el sonido correspondiente. El TFG propuesto deberá cumplir los requisitos expuestos anteriormente (generar una representación gráfica y reproducir el sonido) para partituras de una sola voz, en clave de sol, con compases dentro del rango {2/4, 3/4, 4/4, 6/8, 9/8}, para cualquier clave o tonalidad (número de bemoles o sostenidos en la armadura), con figuras y silencios que abarquen el rango de duraciones {redonda, blanca, negra, corchea, semicorchea, fusa, semifusa} y que puedan incluir notas con puntillo y/o alteraciones (sostenido, bemol, becuadro). Como objetivo secundario, a abordar en función del éxito logrado en lo recién comentado, quedaría la ampliación del proyecto a partituras de una sola voz también, que puedan ir en clave de fa, o que puedan incluir otros tipos de compases y elementos más particulares como los dobles puntillos.

XML Diary File

On the 15th of April, 1897, a 19 year-old European resident of Baghdad, named Alexander Richard Svoboda, set out on a long journey to Europe by caravan, boat and train. From a large and influential family of merchants, artists, and explorers settled in Ottoman Iraq since the end of the 18th century, Alexander traveled in the company of his parents and a departing British diplomat accompanied by his retinue. They followed a circuitous route through the Middle East to Cairo and thence to Europe on a three and a half month journey which Alexander described day-by-day in a journal written in the Iraqi Arabic of his time.

Plutarch's chemistry of stones and metals: conceptions and explanations. With an appendix on the TheSu XML annotation scheme

This dissertation presents a systematic and analytic overview of most of the information related to stones, minerals, and stone masonry which is found in the corpus of Plutarch of Chaeronea, combined with most of the information on metals and metalworking which is connected to the former. This survey is intended as a first step in the reconstruction of the full landscape of ‘chemical’ ideas occurring in Plutarch’s writings; accordingly, the exposition of the relevant passages, the assessment of their possible interpretations, the discussion on their implications, and their contextualization in the ancient traditions have been conducted with a special interest in the ‘mineralogical’ and ‘metallurgic’ themes developed in the frame of natural philosophy and meteorology. Although in this perspective physical etiology could have come to acquire central prominence, non-etiological information on Plutarch’s ideas on the nature and behaviour of stones and metals has been treated as equally relevant to reach a fuller understanding of how Plutarch conceptualized and visualized them in general, in- and outside the frame of philosophical explanation. Such extensive outline of Plutarch’s ideas on stones and metals is a prerequisite for an accurate inquiry into his use of the two in analogies, metaphors, and symbols: to predispose this kind of research was another aim of the present survey, and this aim has contributed to shape it; moreover, a special attention has been paid to the analysis of analogical and figurative speaking due to the nature itself of a large part of Plutarch’s references to stones and metals, which are either metaphorical, presented in close association with metaphors, or framed in analogies. Much of the information used for the present overview has been extracted —always with supporting argumentation— from the implications of such metaphors and analogies.

Validação de escalas para avaliação do amor patológico

CONTEXTO: Diversas metodologias foram desenvolvidas para validar instrumentos psicométricos. No entanto, na literatura científica, há escassez de instrumentos para avaliar os relacionamentos amorosos. OBJETIVO: O presente trabalho tem como objetivo validar para o português o conteúdo dos instrumentos autoaplicáveis Love Attitudes Scale (Escala de Atitudes do Amor - Hendrick et al., 1998), Relationship Assessment Scale (Escala de Avaliação do Relacionamento - Hendrick, 1988) e Adult Attachment Types (Tipos de Apego do Adulto - Hazan et al., 1987), levando em consideração o contexto cultural brasileiro e, consequentemente, possibilitando que o estudo do amor patológico seja viável na população brasileira. MÉTODOS: Tal processo envolveu quatro etapas: (1) tradução para o português, (2) retrotradução, (3) apresentação da versão corrigida para profissionais de saúde mental e estudantes universitários e (4) aplicação da versão final em amostra da população-alvo utilizando uma escala analógico-visual. RESULTADOS: As escalas foram facilmente compreendidas e discriminaram significativamente indivíduos com amor patológico de voluntários saudáveis. CONCLUSÃO: Nossos resultados mostram que a versão brasileira desses instrumentos é válida e pode ser usada em investigações envolvendo relacionamentos amorosos.
