  abstract = {This paper presents solutions and lessons learned in FinnONTO project carried out in
  Finland in 2003–2007. The paper focuses on three aspects of interoperability of digital
  collections. First, transforming thesauri to ontologies. Second, publishing ontologies for the
  use of indexers and content providers. Third, ontology based methods for improving end
  user access to digital collections. 
  The first aspect is analysed through case studies done with Finnish thesauri. The second
  is discussed by presenting the ONKI ontology server. The last aspect is demonstrated in
  the scope of the semantic portal CultureSampo for publishing cultural heritrage on the
  Semantic Web.},
