The added clarity in use of terms and diagrams helps a lot. I did find a few relatively minor items that I still wish to ask that you fix. Instead of doing the usual "change this to that" PID format I just made the proposed changes directly in the text, which I have attached with Track Changes turned on. For transparency, I will tell you where to look:<o:p></o:p></span></p><p class=MsoNormal style='margin-left:36.0pt'><span lang=EN-US> <o:p></o:p></span></p><p class=MsoNormal style='margin-left:36.0pt'><span lang=EN-US>Sec 1.1: fixed the definition of an OAIS to align with the usual notion of what a "system" is:<o:p></o:p></span></p><p class=MsoNormal style='margin-left:36.0pt'><span lang=EN-US> <o:p></o:p></span></p><p class=MsoNormal style='margin-left:72.0pt'><span lang=EN-US style='color:#0070C0'>An OAIS is an Archive system consisting of hardware, software, and procedures developed and operated by an organization.
