Theses and Dissertations Digital Library: Ten years of Open Access and Open Archives in Brazil

Open Access and Open Archives are approaches for scienti c information dissemination that can be supported by di erent software platforms. These platforms need to be integrated if a repositories federation is desired. However this integration deals with di erent metadata schemes that need to be normalized and integrated in order to allow information systems to share data. The Brazilian Digital Library of Theses and Dissertations is an example of integration such systems and it is presented in this paper.
