The standard defines a set of responsibilities that an OAIS archive must fulfil and this allows an OAIS archive to be distinguished from other uses of the term archive.<o:p></o:p></span></p><p class=MsoNormal style='margin-top:6.0pt'><span style='font-size:12.0pt;font-family:"Times New Roman",serif'>Since its adoption as both a Consultative Committee for Space Data Systems (CCSDS) and an ISO standard, the OAIS Reference Model has been welcomed and widely adopted by virtually all types of digital preservation communities. Most modern digital preservation initiatives reference the OAIS Reference Model standard. It has also been widely used by organizations to inform their implementations of new or upgraded preservation systems. <o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><b><span style='font-size:18.0pt;font-family:"Times New Roman",serif'>Five Year Review<o:p></o:p></span></b></p><p class=MsoNormal style='margin-top:6.0pt'><span style='font-size:12.0pt;font-family:"Times New Roman",serif'>In compliance with ISO and CCSDS procedures, a standard must be reviewed every five years and a determination made to reaffirm, modify, or withdraw the existing standard. The Reference Model for an Open Archival Information System (OAIS) standard was approved as CCSDS 650.0-B-1 in January 2002 and was approved as ISO standard 14721 in 2003. A comment period for that first issue of the OAIS standard was held at the end of 2006. Based on the comments received, CCSDS began work on a new issue of OAIS. Issue 2 of OAIS, CCSDS 650.0-M-2, was published in June 2012 and was approved as an update to ISO 14721 in August 2012. <o:p></o:p></span></p><p class=MsoNormal style='margin-top:6.0pt'><span style='font-size:12.0pt;font-family:"Times New Roman",serif'>The Issue 2 updates include clarifications to many concepts, in particular Authenticity with the concept of Transformational Information Property introduced; corrections and improvements in diagrams; addition of Access Rights Information to Preservation Description Information. With those updates the OAIS standard continues to garner widespread and growing recognition and acceptance in the digital preservation communities. <o:p></o:p></span></p><p class=MsoNormal style='margin-top:6.0pt'><span style='font-size:12.0pt;font-family:"Times New Roman",serif'>While the current issue of the standard can be reaffirmed given its wide usage, it may also be appropriate to begin another revision process. As with the previous update, our view is that any revision must remain backward compatible with regard to major terminology and concepts. Further, we do not plan to expand the general level of detail nor will the standard be changed from a reference model to an implementation design. Archive implementation standards or implementation profiles or detailed archival process standards or protocols should be addressed but they would become separate standards and would be developed through separate CCSDS projects. A particular interest for the current OAIS update is to reduce ambiguities and to fill in any missing or weak concepts and to add useful terminology. To this end, a comment period has been established. <o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><b><span style='font-size:18.0pt;font-family:"Times New Roman",serif'>Comment Process<o:p></o:p></span></b></p><p class=MsoNormal style='margin-top:6.0pt'><span style='font-size:12.0pt;font-family:"Times New Roman",serif'>We are soliciting recommendations for updates that will reduce ambiguities or improve missing or weak concepts.
