Concerning with the access to scientific information drives actions by information and communication technologies. The repositories, which gather all the scientific production of an institution, have to be aligned to the principles established by the Information Architecture as a way to be more efficient and effective. This study presents the analysis of the institutional repository of the Federal University of Brasília in order to verify if it uses the principles proposed by Morville and Rosenfeld. This repository presents compatibility with some principles; however, it needs to solve problems regarding the system of search, accessibility, and service to the users' demands.

RESUMEN El Modelo de Referencia oais : Sistema de Información de Archivo Abierto es una norma iso , desarrollada originalmente por el Consultative Committee for Space Data Systems ( ccsds ), que define los procesos necesarios para preservar y acceder a los objetos de información de forma efectiva y a largo plazo, y establece un lenguaje común que los describe. Ha sido aceptado por buena parte de la comunidad implicada en la preservación digital, aunque no se trata de una arquitectura de aplicación, lo que ha llevado a numerosos expertos a poner en duda su utilización. El trabajo analiza las características del modelo y la controversia científica producida por su puesta en práctica y su capacidad de adaptarse a los diferentes escenarios. The Open Archive Information System ( oais ) reference model is an iso standard originally developed by the Consultative Committee for Space Data Systems ( ccsds ). The model serves to define the processes for effective, long-term preservation of information, while ensuring access to them. This model also provides a common language for describing these objects and has been widely accepted in the digital preservation community. Since it is not an application architecture, many experts have called into question its use. This paper examines the features of the model and the scientific controversy arising from its adaptability to diverse scenarios and wide-spread implementation. [ABSTRACT FROM AUTHOR]
