Abstract
(English)
A query language for Digital Libraries is presented, which offers access to documents by structure and sophisticated usage of metadata. The language is based on a mathematical model of digital library documents, centered around a multilevel representation of documents as versions, views and manifestations. The core of the model is the notion of document view, which is recursive, and captures the content and structure of a document. The metadata representation distinguishes between formats and specifications, so being able to accommodate different metadata formats, even for the same document. A query is a logical formula, and its result are the digital library documents satisfying the user query.
