    Computing the Importance of Schema Elements Taking Into Account the Whole SCHEMA

    Conceptual Schemas are one of the most important artifacts in the development cycle of information systems. To understand the conceptual schema is essential to get involved in the information system that is described within it. As the information system increases its size and complexity, the relative conceptual schema will grow in the same proportion making di cult to understand the main concepts of that schema/information system. The thesis comprises the investigation of the in uence of the whole schema in computing the relevance of schema elements. It will include research and implementation of algorithms for scoring elements in the literature, an study of the di erent results obtained once applied to a few example conceptual schemas, an extension of those algorithms including new components in the computation process like derivation rules, constraints and the behavioural subschema speci cation, and an in-depth comparison among the initial algorithms and the extended ones studying the results in order to choose those algorithms that give the most valuable output

    This paper reviews the laws and norms regulating access to public documents in Spain, as well as their actual implementation in archival institutions and their consequences for historical research. Despite the liberal character of the early laws enacted in the democratic period, the publication of subsequent privacy regulations has severely curtailed access to historical documents. The vagueness and contradictions of the relevant norms, combined with the negligence typical of Spanish public archives, are posing greater burdens in researchers’ access to archival material. A situation worsened by the recent governmental decision to extend the scope of the State Secrets Act (Ley de Secretos Oficiales) to cover a number of issues relating to foreign policy. As a result, historians are finding more and more difficult the study of recent Spanish History.El artículo repasa la normativa española sobre el derecho de acceso a la documentación pública, su aplicación en los archivos y las consecuencias para la investigación histórica. Aunque las primeras leyes promulgadas en el periodo democrático fueron muy aperturistas, el desarrollo de la legislación sobre protección de datos personales ha restringido de forma severa el acceso a la documentación histórica. La indefinición y las contradicciones de las sucesivas normas, junto con las malas prácticas persistentes en la administración de los archivos públicos, están ocasionando trabas injustificadas para acceder a la documentación. A estos problemas se ha sumado recientemente la decisión gubernativa de extender la protección que proporcionada la Ley de Secretos Oficiales a múltiples materias relacionadas con la política exterior. Con todo ello, los historiadores encuentran graves dificultades para estudiar los periodos más recientes de la historia española
