English abstract

A query language for xml should be flexible enough to cover the whole range of information sources that can be labelled by xml, including databases and web documents. In this article we present a comparative analysis of several query languages that have been created for xml. We study sets of desirable traits both from the point of view of the semistructured data community (that emphasise especially very large databases, the integration of heterogeneous sources and data transformation into common interchange formats), and from the point of view of the information retrieval community (that emphasise especially full-text searches, manipulation of the sets of results, inclusion relationships, distances, and ranking of the result documents).

Spanish abstract

Un lenguaje de consulta para xml debería ser lo suficientemente flexible para cubrir el espectro de fuentes de información que xml permite etiquetar, incluyendo bases de datos y documentos distribuidos a través del web. En este artículo se presenta un análisis comparativo de diversos lenguajes de consulta que han surgido para xml. Se estudian conjuntos de características deseables tanto desde la perspectiva de la comunidad de datos semiestructurados (la cual pone el énfasis principalmente en los grandes almacenes de datos, la integración de fuentes heterogéneas y la transformación de datos en formatos comunes de intercambio), como desde la perspectiva de la comunidad de recuperación de información (que pone el énfasis principalmente en las búsquedas de texto, la manipulación de conjuntos de resultados, las relaciones de inclusión, las distancias y la ordenación por relevancia de los documentos resultado).
