Abstract

Abstract: Policy-analyses require a range of activities like relating data to each other, visualizing its impact and interpretation of the results. The linking of data can be done in various ways. In this paper we postulate that merely linking data is not enough to make use of open data and that metadata are key enablers for the effective use of linked open data (LOD) in policy-making. Metadata are computer-readable data about a dataset and contain information for the discovery, the context and the detailed use of data. We illustrate the value of metadata by presenting two use cases, derive requirements from the use cases and provide elements of an architecture. The paper shows that metadata help to fulfill the requirements for the use of LOD and that the Common European Research Information Format (CERIF) and LOD can be used to build the architecture for these metadata.
