This paper describes the infrastructure of the National Digital Library in Portugal. The requirements emerged from the definition of the resources to be manipulated and the services to be supported. It was given a special attention to scalability, as also to community building open standards, open solutions, and reusable and cost effective components. The structural metadata for the content resources is METS, and generic bibliographic metadata format is UNIMARC, EAD or Dublin Core. The resources identifiers are processed and resolved as simple but very effective PURL identifiers, supported by a specialized resolution service. The storage for immediate access is provided by open file systems, such as LUSTRE. The storage for long-term preservation it supported by ARCO, a locally developed solution. All the components can run on GNU/Linux systems.
