We study the problem of updating XML views defined over XML documents. A view update is performed by finding the base updates over the underlying data sources that achieve the desired view update. If such base updates do not exist, the view update is said to be untranslatable and rejected. In SQL, determining whether a view update is translatable is performed using schema level analysis, where the view definition and the base schema are used. XML schemas are more complex than SQL schemas, and can specify recursive types and cardinality constraints. There are two kinds of view updates: single view element update, where the user requires for an update over a particular view element, and a set of view elements update, where the user requires for an update over all view elements that satisfy a given XPath over the view. Accordingly, we propose one solution for each kind of view update problems based on schema level analysis for determining whether an update over XML views is translatable and for finding the translation if one exists, while considering the features of XML schemas.

Para tanto, apresenta-se um modelo capaz de estimar o poder de mercado e a escala de produção com o que se torna possível medir a produtividade total de fatores em concorrência imperfeita. A análise realizada para o conjunto da indústria indica elevado poder de mercado até 1999 e aumento significativo após a mudança de regime cambial. Para o conjunto da indústria são identificados retornos decrescentes de escala entre 1996 e 1998, retornos crescentes de 1999 até 2002 e novamente retornos decrescentes entre 2003 e 2007. Contudo, não foi possível apontar em quais setores as quebras de estrutura são significativas. A produtividade mostrou elevado crescimento em 1999 e taxas negativas após 2003. / This work focuses on the time path of productivity in the Brazilian manufacturing sector and its behavior in the face of structural shocks during the period 1994 to 2007. It presents a model that is capable of estimating the market power and scale effects in order to measure the total factor productivity under imperfect competition. The analysis for the entire industry indicates a high degree of market power by 1999 and a significant increase in it after the change of the exchange rate regime. Also, for the entire industry, decreasing returns to scale are identified between 1996 and 1998, followed by increasing returns from 1999 to 2002 and, again diminishing returns between 2003 and 2007. However, it was not possible to identify sectors in which the structural shocks were significant. The productivity showed high growth rates in 1999 and negative rates after 2003.

XML is a very versatile data format that has been used to represent many different kinds of data, including web pages, books, business and accounting data, programming interfaces, vector graphics, system logs, and games. In a short span of time, it has gained wide acceptance as the document and data standard on the web. As more and more XML data gets generated everyday, a lot of research focus has been on query languages for XML. The World-Wide Web Consortium (W3C) has chosen XQuery as the standard language for querying XML. From an end-user point of view, XQuery sacrifices usability for expressiveness. We introduce FoXQ, a visual language that enables end users to query XML. FoXQ brings a lot of the functionality of XQuery within the reach of the end users without getting them embroiled in the intricacies of XQuery syntax. The query interface is form-based and the query model is based on a document metaphor in which the users formulate queries by filling out forms. / Graduation date: 2004

This paper analyzes the visions, schemas, and vocabularies of prominent rights expression languages, including Creative Commons, METS, ODRL, and MPEG-21. The paper extends Michel Callon’s sociological insight that all forms of human agency are multiple and diverse. Callon argues, in the context of economic sociology, that one must constantly decide between a strategy emphasizing “framing” as the norm with “overflows” treated as leaks, or conversely a strategy accepting “overflows” as the norm with “framing” as inherently imperfect. Callon’s categories are extended, through a modeling exercise, to the classification of current metadata schemes. The analysis suggests that metadata developers should explore what semantic choices and strictures are left out of metadata schemes, as well as those that are included. Such a thought exercise is especially useful in distinguishing areas suited for XML rights markup extensions.
