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.
