The University of Aveiro is currently developing SInBAD, an integrated system for digital libraries and archives. The aim of the project is to build an information system to support the aggregation of multimedia documents such as books, photographs, and audiovisual resources. All these resources are part of the academic life and identity of the University. The architecture adopted in SInBAD is divided into 3 subsystems - Library, Archive and Jazz - and is Web Service oriented. Also, documents are distributed by several Agents in a dynamic manner. The basic description model used in the documents is the element set defined by the Dublin Core Metadata Initiative, although each subsystem may use specific data structures according to the document type and format. In this paper we present the created system, pointing out the interoperability and the web service oriented architecture. Also, despite its distributed nature, users may search simultaneously in all documents.
