OAISISO 14721: functional modelISO 16363: guidelines for certification17-5-2013An OAIS is an Archive […] that has accepted theresponsibility to preserve information and make itavailable for a Designated Community.
Key concepts for preservation- Usability: Keeping the data readable for the designatedcommunity- Integrity: Keeping data from corruption:technical properties, fixity checking- Authenticity: audit-trail of actions within the digital lifecyclein preservation metadata17-5-2013
