The Museum Data Exchange, funded by The Andrew W. Mellon Foundation, brought together a group of nine museums and OCLC Research to create tools for data sharing, build a research aggregation and analyze the aggregation. The project established infrastructure for standards-based metadata exchange for the museum community and modeled data sharing behavior among participating institutions. Tools T...

An increasing number of universities in Sweden make their university research results available in electronic form. Technical solutions for electronic publishing are different, but the aim is usually the same to facilitate the efficient discovery and dissemination of content. Five universities in Sweden have already agreed on a common XML schema for publishing electronic documents. The DiVA por...

Reusability always has been a controversial topic in Digital Library (DL) design. While componentization has gained momentum in software engineering in general, there has not been broad DL standardization in component interfaces. Recently, the Open Archives Initiative (OAI) has begun to address this by creating a standard protocol for accessing metadata archives. We propose that the philosophy ...

The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) has been widely adopted since its initial release in 2001. Initially developed as a means to federate access to diverse e-print archives through metadata harvesting and aggregation, the protocol has demonstrated its potential usefulness to a broad range of communities. Two years out from the release of the stable production...

Numerous institutions and organizations need not only to preserve the material and publications they produce, but also have as their task (although it would be desirable it was an obligation) to publish, disseminate and make publicly available all the results of the research and any other scientific/academic material. The Open Archives Initiative (OAI) and the introduction of Open Archives Init...

We present the results of a feasibility study using shared, existing network-accessible infrastructure for repository replication. Our goal is not to “hijack” other sites’ storage, but to take advantage of protocols which have persisted through many generations and which are likely to be supported well into the future. We utilize the SMTP and NNTP protocols to replicate both the metadata and th...

The Indiana University School of Library and Information Science opened a new research laboratory in January 2003; The Indiana University School of Library and Information Science Information Processing Laboratory [IU IP Lab]. The purpose of the new laboratory is to facilitate collaboration between scientists in the department in the areas of information retrieval (IR) and information visualiza...

We present star-fish, a focus+context approach to visualizing federations of large repositories that is based on the notion of starfields and is enhanced by functionality that allows users to keep track of the context of objects of their interest. This is accomplished through successive refinements of starfield representations in which areas of interest are magnified whereas surrounding areas a...
