Modelo de Metadados para descrição de recursos eletrônicos na Web

Abstract

The increasing status of the Web as a tool for resources publishing, emphasized bythe progress in the information retrieval domain, has leaded to an information overhead,difficult to manage. In this context, the use of metadata provided by the own authors’ Web documents has been considered by many researchers as the adequate solution to turn out to be more accurate the research of electronic documents. The automatic indexing strategiesof documents contents used by most of the current search tools have not been adequate to answer to the information increasing requirements. The metadata proposal described in this work is named Digital Objects Model for Electronic Documents (MODDE). Its purpose is to allow the management of documents on the Web, based on their intellectual content, helping the non-expert user to adequately describe his documents properties according to several metadata standards.The proposed model is based on recent metadata projects, such as Warwick architecture, developed for the Web environment, and on the digital object concept proposed by Kahn and Wilensky architecture to represent information resources managedby distributed digital libraries. Its hierarchical multi-layer structure allows a coherent and standardized organization of the document content integrated to the descriptions associated to this content.
