This paper introduces an extension of DALI, a framework for data integration and visualisation. When integrating new data, DALI automatically tries to recognise the schema and contents of the file, semantically lift them, and annotate them with existing ontologies. The extension presented in this paper allows users to import data from external data portals, namely portals using CKAN or Socrata, based on the results of a search query or by selecting individual datasets. Furthermore, we perform a semantic expansion of the search terms provided by the user in order to identify datasets that might still be relevant while not containing the exact search terms.
