Participants: DB, DS, JG

2.      Core PAIS GB

1.NamePreservationRule and associated elements (review and discussion from DS material)
Ok with the updates, with the following:

=> A=>(DS): clarify the "source name", and add something like "But also how the name should be preserved on the archive side" after "within the Transfer Objects derived from a given Transfer Object Descriptor".

2.SIP section (review and discussion from JG material)

Use of MIME type: possibly defined in the TO Descriptor. Could also be included in the XFDU in a separate way. Explanation should be given to avoid conflict.

=> A=>(DS): review JG's material

=> A=>(JG): add examples section, add a paragraph on SIP extension, MIME type ...


*Annex in document structure, ok to add: "Annexes B to E contain the descriptors, SIP constraints and extract of a SIP manifest from the 4 practical use cases NASA ISEE, ESA SAFE, CNES COROT, BnF METS."

WG ok to suppress the inclusion of PAIS descriptors in the GB (annex A).

Figure 7-9: seems interesting as an overall MOT/SIP constraints figure. Perhaps better in section 3?

=> A=>(DB): propose a new section 3.2.3 at the end of section 3 as a summary of section 3 (MOT and SIP constraints). Check the different figures that are not align with 7-9 (3-4 ...).

4.Format (review and discussion from DB material)

Discussion on the case where the Data Object is made up multiple files: different options to be expanded (same format, if not, use companion TO: see DS' today email).

DB-> paragraph updated and sent to the group after the telecon.

5.Other PAIS points
*TOPIC section 4.7.3:  replace by "each project should adopt a common policy for restricting the ID values, e.g. min one char, printable characters, pattern."

6.Still to be done (apart from the previous actions)


=> A=>(DS): add an example of Associated Descriptor Data ID, plus annex A.

*section 7 ->JG
*some remaining comments (not a lot) -> TO BE REVIEWED
*at the end: figure numbering (particularly section 4), and ref to figure, tables and annexes in the whole document -> DB

3.      Other topics:
1.MACAO, SANA and other books to be reviewed (from Peter Shame's material): not enough time to discuss this point (next telecon)

2.List of DAI documents (from Mario Merri email)-> DB ok, to be checked again by DS and JG, particularly for old documents

=> A=>(JG, DS): check the list of DAI documents, particularly for old documents.

3.DAI standards review: documents to be reconfirmed:
1.      XFDU BB 5 year review is due since Sept 2013
2.      EAST BB 5 year review is due in June 2015
3.      PAIMS MB 5 year review due in June 2015
=> A=>(DB): ask for reconfirmation

4.Discussion with C. Arviset from ESAC this morning (responsible for ESA Space Data Archive)
Could be interested in DAI WG standards.
At a first step, will follow the discussion through the mailing list.
