RESUMO

O conceito de repositórios digitais distribuídos e interoperáveis - sejam eles bibliotecas ou arquivos digitais - para ser viável, depende fortemente de uma infra-estrutura de identificação persistente e da confiabilidade do esquema de links entre recursos informacionais distintos, porém relacionados, de forma a assegurar ao usuário o acesso contínuo e conveniente aos conteúdos digitais. Neste trabalho, descreve-se o atual estado da arte da identificação persistente na Internet e da vinculação por links, tendo como foco a interoperabilidade das bibliotecas digitais de arquitetura aberta. Contrastam-se as diversas abordagens e analisam-se os mais importantes esquemas e o relacionamento entre eles: URN, PURL, DOI, CrossRef, Handle System and OpenURL.

Palavras-chave: bibliotecas digitais; identificadores persistentes; URI; URN; PURL; DOI; CrossRef; Handle System; OpenURL.


ABSTRACT

To be feasible, the concept of distributed and interoperable digital repositories - libraries or archives - depends strongly on an infrastructure of persistent identification, as well as on the reliability of the linkage scheme between distinct but related information resources, in order to assure to the user a continuous and convenient access to the digital contents. This paper describes the current state-of-the-art of persistent identification and linkage in the Internet, focusing on the interoperability of the open digital libraries. It contrasts various approaches to the issue and analyzes the most important schemes and their relationship: URN, PURL, DOI, CrossRef, Handle System and OpenURL.

Keywords: digital libraries; persistent identifiers; URI;  URN; PURL; DOI; CrossRef; Handle System; OpenURL.
