<br><font size=2 face="Calibri">Do these types of Use Cases make sense.
I’d like a sanity check before going any further.</font>
<br><font size=2 face="Calibri"> </font>
<br><font size=2 face="Calibri">NOTE: Consumer and Producer roles may be
fulfilled by people, systems, organisations or OAISes</font>
<br><font size=2 face="Calibri"> </font>
<br><font size=2 face="Calibri">Overall aim: Consumer should be able to
use the OAIS-IF specifications to create software which allows the following
use cases to be implemented</font>
<br><font size=2 face="Calibri"> </font>
<ol>
<li value=1><font size=2 face="Calibri">Consumer identifies Information
wanted from the OAIS.</font>
<ol type=a>
<li value=1><font size=2 face="Calibri">The Information could be:</font>
<br><font size=2 face="Calibri">
i. AIP</font>
<br><font size=2 face="Calibri">
ii. Subset of Content Data Object</font>
<br><font size=2 face="Calibri">
iii. Any of the components of the related
AIP e.g. Provenance</font>
<li value=1><font size=2 face="Calibri">Consumer may need to be authenticated</font></ol>
<li value=1><font size=2 face="Calibri">Consumer gets DIP from OAIS</font>
<ol type=a>
<li value=1><font size=2 face="Calibri">Consumer may need to be authenticated
and checked to have appropriate authorisation</font>
<li value=2><font size=2 face="Calibri">DIP packaging information must
be agreed</font>
<li value=3><font size=2 face="Calibri">Transmission protocol must be provided</font></ol>
<li value=2><font size=2 face="Calibri">Consumer extracts Information Object
(CIO, Provenance Object etc) from AIP</font>
<ol type=a>
<li value=1><font size=2 face="Calibri">Consumer must have Data Object
and at least the immediately required Representation Information</font>
<br><font size=2 face="Calibri">
i. E.g. for FITS file would
need RepInfo which consists of FITS software plus associated dictionary</font>
<ol>
<li value=1><font size=2 face="Calibri">FITS s/w Information Object may
consist of a Data Object which is JAVA class, in which case its RepInfo
might be a Java Virtual Machine</font></ol><font size=2 face="Calibri">
ii.
For PDF just need a PDF viewer</font></ol>
<li value=1><font size=2 face="Calibri">Consumer uses Information Object
to perform Preservation Objectives</font>
<ol type=a>
<li value=1><font size=2 face="Calibri">Consumer have Data Object and its
Representation Information</font>
<li value=2><font size=2 face="Calibri">Consumer can use the RepInfo to
extract structural elements and appropriate semantics from the data object</font>
<br><font size=2 face="Calibri">
i. If, for example, the
Information Object is Provenance Information then one should be able to
extract a list of events and for each event the agent, time etc</font>
<br><font size=2 face="Calibri">NOTE: We may need to define simple interfaces
for each of the PDI components</font></ol>
<li value=1><font size=2 face="Calibri">Producer agrees submission agreement
with the OAIS including SIP definitions </font>
<ol type=a>
<li value=1><font size=2 face="Calibri">Need to exchange Information Object
which consists of an agreement TBD</font>
<li value=2><font size=2 face="Calibri">Alternatively this could be handled
out of band i.e. not specified in the OAIS-IF</font></ol>
<li value=2><font size=2 face="Calibri">Producer sends SIP to the OAIS</font>
<ol type=a>
<li value=1><font size=2 face="Calibri">….</font></ol>
<li value=3><font size=2 face="Calibri">….</font><tt><font size=2>_______________________________________________<br>
