Abstract

Libraries, archives and museums are increasingly committed to making their resources available through online digital repositories. However, progress in this area has been stalled for years, both in the functional design arena and in the relevant technology. Now, a group of universities with a long tradition in this area has created the Hydra Project: a framework that allows each institution to create their own repository and provides all needed utilities. This article describes the experience of the Documentation Centre and Museum of the Performing Arts, one of the first European partners to opt for this new generation of repositories, when faced with this challenge. It aims to explain what was done and how, the problems encountered, the mistakes and successes, and finally, the conclusions that can be drawn from the whole process.

Abstract

Open data are a basic infrastructure for the creation of business, products, and services. To analyze their usefulness, the differences between data access, and dissemination, and reuse must be taken into account. The objective of this research is to analyze how Berners-Lee’s 5-star model and other factors help evaluate the quality of data and its use in the Barcelona open data portal, including its relationship to downloads and themes. Results show that it may be of interest to include aspects such as data updating frequency and geolocation in the models that measure the quality of data for reuse.
