Metadata interoperability in public sector information

Over recent years, there has been a worldwide growing need for interoperability among the systems that manage and reuse Public Sector Information. This paper explores the documentation needs for Public Sector Information and focuses on metadata interoperability issues. The research work studies a variety of public sector information metadata standards and guidelines internationally accepted and presents two methodologies to obtain interoperability: The first develops an Application Profile, while the second is based on the semantic integration approach and results in the creation of an ontology. The outcomes of the two approaches are compared under the prism of their scope and usage in terms of interoperability during the metadata integration process

Mapping Encoded Archival Description to CIDOC CRM

In this paper we analyze the semantics of the archival description, expressed through the Encoded Archival Description. Through this analysis it is concluded that an EAD document is a hierarchy of documentation elements and attributes and that through this documentation the archive is semantically expressed through three di erent hierarchies (hierarchy of physical objects, hierarchy of information objects and hierarchy of linguistic objects). The semantic views of the archive as well as their interrelationships are mapped to the CIDOC CRM
