</ol>
<div>DB : synthesis of stages description by EC, DB, MM, JG in a spreadsheet, and updated LTDP figure on Stewardship/Curation/Preservation/Consolidation, by JG.</div>
<div> </div>
<div>MM : asks for a high level and clear description of each of the 4 stages, rather than a more detailed description. Important to say: no need to speak about preservation, but identify what’s going on in each stage –even if no impact on preservation (the
current description focuses too much on preservation).</div>
<div>For example: archiving repeats what is in OAIS, think of what are we going to talk about; Implementation: a lot of decisions are made at this stage; Operation: creation and collect of data and associated information link with provenance.</div>
<div> </div>
<div>DB: ok, with the fact that this spreadsheet also helps to understand what is expected in these stages.</div>
<div> </div>
<div>DS: take 2 very different examples/scenario: one from a library (digitization of newspapers), one from space mission, and think about the steps considering these examples.</div>
<div> </div>
<div>Synthesis of the discussion: 2 directions:</div>
<div>*use 2 examples and see how the steps apply</div>
<div>*write a high level and generic description of each of the stages.</div>
<div><font face="Times New Roman" size="3"><span style="font-size:12pt;"> </span></font></div>
<div><b>A=>(JG):</b> propose a high level description for each stage; apply the stages on the 2 examples library digitization/space mission.</div>

<div> 2. <b><u>GREEN BOOK</u></b></div>
<div> </div>
<div> <b>2.2 </b><b><u>Core document</u></b></div>
<div> </div>
<div>Section 4.1.1 reviewed (ok)</div>
<div>Tabular representation is welcome but question remains about their systematic use (need an XML version in annex ?)</div>
<div> </div>
<div>CCSD0014: equivalent to TO Descriptor, and CCSD0015: equivalent to Collection Descriptor</div>
<div> </div>
<div>==> <u>Action Stephane</u> from MM: explain more the CCSD0015: how it is registered and reference where more information could be found on that subject</div>
<div> </div>
<div>Don: descriptorModelID has to be changed on any XSD change (specialization), the Archive has to maintain the versions</div>
<div> </div>
<div>Section 4.6.1 about PAIS XSD description should remain here for the time being</div>
<div> </div>
<div> </div>
<div>« open » enumeration technique is cumbersome (TBC)</div>
<div> </div>
<div>Comment from previous telecons on method </div>
<div>* (Daniele): there are steps that conform to the PAIMAS process (first model, SIP constraints, then transfer and validation).</div>
<div>* Link between the data base on the Archive side, and the PAIS XML elements: example on how to match both (core document, test case?).</div>
<div> </div>
<div>The following paragraph will be suppressed if ok:</div>
<div><font size="2"><span style="font-size:10pt;"><b><u>XML namespace for PAIS </u></b></span></font></div>
<div> <font color="#1F497D"> </font></div>
<div> </div>
<div>It is agreed that not all positions where a pais :any element are possible have to be documented in the GB. Only a few example are necessary or even one.</div>
<div> </div>
<div>More concrete example should be provided than the abstract « foo »/« bar » currently proposed. Typical example would be a Collection holding a pais :any with the author of the descriptor, the Collection name/ID in the Producer semantic, or anything else
that could be specific to the Producer or the Archive side but not provided in the PAIS definitions.</div>
<div> </div>
<div>SM: Reminded that « true » restrictions of XML Schema guarantees that the original PAIS XML Schema’s rule are still applicable. Any instance following a restriction follows the original ones.</div>
<div> </div>
<div>SM: The use of restrictions does not impose any system to use the derived PAIS schemas. Therefore, the restricted schemas have not to be shared with any user of the produced SIPs. The project specific schemas could even be discarded without losing control
of the produced SIPs.</div>
<div> </div>
<div>=> D – (DS) The rightmost column of the table in §4.6.4 shall be renamed « Restriction » instead of « Content »</div>
<div> </div>
<div>MM: It is not clear that this table should be kept in that form or discarded at the end, but the target should not spend too much pages on that topic.</div>
<div> </div>
<div>WG: restrictions may be interesting for implementers and as such should be documented, but it is not clear if this should be proposed as a recommendation or a best practice.</div>
<div> </div>
<div>SM: reminded that restricting elements such as the maxOccurrence’s should be a recommended practice since it can be very difficult to implement interoperable software exchanging elements of xs:nonNegativeInteger type.</div>
<div> </div>
<div>SM: proposed to add prepared templates of restricting XML Schemas in annex. Something that could help implementers to quickly setup the restrictions of their needs.</div>
<div>WG: adding XML Schema’s in annex may not be so helpful because cut and paste from PDF may be very cumbersome.</div>
<div> </div>
<div>=> D – (JG) these XSD shall be placed side to the originals.</div>
<div> </div>
<div>SM: The problem is similar to other GB resources as the use case descriptors or the software prototypes.</div>
<div> </div>

<div><b><u>Preservation process </u></b></div>
<div> </div>
<div>DB: LOTAR representative is ok with "preservation", but not with "curation" (this word is not used in the community).</div>
<div> </div>
<div>To be done: analyse and suggest, at different stages of the project (during data lifecycle), what should be done on an archiving point of view.</div>
<div> </div>
<div>Example of main issue: keep documentation up to date (when changes in formats, processing, … are made on the data).</div>
<div> </div>
<div>Daniele explains her point of view: develop a "model" (magenta book) gathering all the basic components of the preservation activity (selection and appraisal, data and metadata preparation, access, maintenance …) that should cover all the data lifecycle
(even when data don't exist), in order to be able to answer the following question: what should be done from the beginning till the end to be able to preserve data, and at what moment? This should be done in a generic way, making links on standards related
to basic components when they exist.</div>
<div> </div>
<div>Suggestion to ask Barbara Sierman of existing works concerning this topic. Mail sent the 7/02 by Daniele.</div>
<div> <font color="red"> </font></div>
<div>Daniele underlines the need for CNES and LTDP group. CCSDS expertise will be very important.</div>
<div> </div>
<div>The PDS has its internal process ; for other agencies (particularly the LTDP member agencies) this process doesn't exist and is required.</div>
<div> </div>
<div>Question on how to make the link between a global process and the PAIMAS phases.</div>
<div> </div>
<div>20131030 Don's email and following discussions:</div>
<div>Don: The process could be focussed on the Archive point of view, and seen an internal OAIS issue for workflow, using then more OAIS concepts.</div>
<div>The "provenance" is practically a big issue, going back to the original information.</div>
<div>"Reprocessing, curation, stewardship" could be maped with OAIS migrations, new versions, …</div>
<div> </div>
<div>Update procedures exist at NSSDC.</div>
<div> </div>
<div>Daniele: appraisal should be the starting point. Workflow, on the Archive side, could begin early in a space project, even when data don't yet exist ; link with the Archive side of the PAIMAS.</div>
<div> </div>
