In this paper, we propose an ontology-based metadata integration methodology for the cultural heritage domain. The proposed real -world approach considers an integration architecture in which CIDOC/CRM ontology acts as a mediating scheme. In this context, we present a mapping methodology from Encoded Archival Description (EAD) and Dublin Core (DC) metadata to CIDOC/CRM, and discuss the faced difficulties.
In this article we analyze the main semantics of archival description, expressed through Encoded Archival Description (EAD). Our main target is to map the semantics of EAD to the CIDOC Conceptual Reference Model (CIDOC CRM) ontology as part of a wider integration architecture of cultural heritage metadata. 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 via 3 hierarchies: hierarchy of physical objects, hierarchy of information objects, and hierarchy of linguistic objects. These semantic views of the archive and its description (e.g., finding aid) as well as their interrelationships are mapped to CIDOC CRM.
In this paper, we explore the use of Social Media in Archives. The last five years the archival services worldwide have started using Social Media for various purposes, such as content delivery and promotion of their work. Based on this fact, we created an online survey that was sent to various archival services in order to see how they are using these platforms and aiming to present comparative results between them (Greek and non-Greek archival services). The results of our research revealed, among others, that there is an extended use of Facebook, YouTube and blogs by the archival services, while the comparison between Greek and non-Greek services revealed a "gap" between the two cases.
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.Keywords: Metadata Interoperability; Public Sector Information; Ontology -based integration; Application Profiles; eGovernment Archives and Library Sciences, Ionian University. 72 Ioanni Theotoki, Corfu, Greece, boudouri@ionio Correspondence to: Lina Bountouri, Laboratory on Digital Libraries and Electronic Publishing, Department of Public Sector InformationIn recent times the evolution of the information society is influencing the life of citizens in developing and developed countries by providing them with innovative approaches and enhanced technological means to access information. One of the main stakeholders in producing and disseminating huge amounts of information is the public sector. Public Sector Information (PSI) are documents, databases and other information (meteorological information, digital maps, traffic data, etc.) produced, collected, stored, etc. by public sector bodies [1]. This information covers a wide range of domains, such as financial, business and legal. The management of PSI deals mainly with facilitating the Public Administration's (PA) transactions and the access, use and reuse of PSI so as to act as the basis for the provision of services within Public Administration and/or to external users (citizens and enterprises, usually called as "customers") [2].PSI's effective management is important given that it enables [3]: (a) the reliable documentation of administrative acts, (b) the successful delivery of governments' services by increasing the efficiency of internal processes in PA, facilitating the communication of citizens with the PA and increasing their involvement in the democratic process, (c) the financial progress, since business activities cannot be realized without well-organized and accurate information (quick and easy access to such information facilitate business to make well-informed choices), and (d) the commercial use of PSI, given that creating an improved infrastructure for the exploitation of the PSI facilitates the creation of information products.Government information is significant for citizens that interrelate with public services on a daily basis and need to be guided and informed promptly in order to easily accomplish their transactions with the public sector [4]. In Greece, for instance, the creation o...
