- In this article, we describe an extension of lookup services in the research information system software VIVO, which can be applied for integration of external distributed data - e.g. concepts from subject authorities, available on the web. The integration of non-concepts is planned as well. The lookup service utilizes SPARQL Protocol and RDF Query Language (SPARQL) endpoints, Representational State Transfer (REST) API and the Skosmos tool as a middleware. The extension has been developed at the German National Library of Science and Technology (TIB) Hannover.
