N2 - This paper reports about current research about the semantic enrichment of data and the implementation of enriched metadata fields into search possibilities. Different data sources when brought together in a portal – as in the case of the Odissei Portal – come with their own metadata standards, and sometimes also datamodels. Obviously, data/metadata harmonisation is a central challenge. Thus, not surprisingly in making the Odissei portal a lot of different data stewards and data scientists work on harmonisation pathways. This paper presents one facet of this work, executed at DANS and demonstrated on the Dataverse repository platform which the Odissei portal is built on. The core of the work concerns automatically supported enrichment of metadata (fields) based on datamining of the data itself and linking to external controlled vocabularies. Semantic web technology provides the tools. We demonstrate first findings and discuss further engineering challenges.
