Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-11-012009enThe proliferation of Web, database and social networking technologies has enabled us to produce, publish and exchange digital assets at an enormous rate. This vast amount of information that is either digitized or born-digital needs to be collected, organized and preserved in a way that ensures that our digital assets and the information they carry remain available for future use. Digital curation has emerged as a new inter-disciplinary practice that seeks to set guidelines for disciplined management of information. In this paper we review two recent models for digital curation introduced by the Digital Curation Centre (DCC) and the Digital Curation Unit (DCU) of the Athena Research Centre. We then propose a fusion of the two models that highlights the need to extend the digital curation lifecycle by adding (a) provisions for the registration of usage experience, (b) a stage for knowledge enhancement and (c) controlled vocabularies used by convention to denote concepts, properties and relations. The objective of the proposed extensions is twofold: (i) to provide a more complete lifecycle model for the digital curation domain; and (ii) to provide a stimulus for a broader discussion on the research agenda.http://creativecommons.org/licenses/by/4.0/International Journal of Digital Curation4134-45 Constantopoulos, Panos Dallas Costis Androutsopoulos, Ion Angelis Stavros Deligiannakis Antonios Δεληγιαννακης Αντωνιος Gavrilis Dimitris Kotidis, Yannis Papatheodorou, Christos Digital Curation Centre DCC Digital Curation Unit
