This paper describes the creation of linked data for cultural heritage domain, using semantic technologies. The Gothenburg city museum data are described according to an ontological model combining a series of upper-level and domain specific ontologies, such as PROTON and CIDOC-CRM, triplified and interlinked with data from LOD, e.g. DBpedia. The implementation is done as a reason-able view of the web of data and the data are loaded in OWLIM semantic repositoyr.
