It is important for Digital Libraries (DL) to be flexible in exposing their content. Typically a DL provides a search/browse interface which allows resources to be found and a service to make the data available for harvesting from/to other DLs. This kind of communication is possible because the structures of different DLs are expressed following formal specifications. In particular in Cultural Heritage, where we need to describe an extremely heterogeneous environment, some metadata standards are emerging and mappings are proposed to allow metadata exchange and enrichment. CIDOC-CRM is an ontology designed to mediate contents in the area of tangible cultural heritage and was published as ISO 21127: 2006 standard. Lately an extension of CIDOC-CRM, known as CRM dig, enables to document information about data provenance and digital surrogates in a very precise way. Another metadata schema suitable for handling museum-related data is LIDO. In this paper we propose a case study where we show how CIDOC-CRMdig and LIDO handle the digital information of an object and specially the data provenance. © 2011 IEEE.
