Minutes 

1. Prototyping status and feedback

The prototyping on ESOC and DLR side is progressing satisfactory. 
Christoph made the WG aware of a potential issue with the ActivityNode 
data structure: in case of sub-activities being defined on the fly, there 
is currently no interface provided by the standard to add these 
sub-activities to the configuration data. It was agreed that this is in 
line with earlier WG decisions to no cover the exchange of configuration 
data in the current standard. In any case, a mission specific exchange of 
the sub-activities information could be provided in case needed.

2. File Formats and XML Schemas 

Roger has made available (see GDrive) the updated Enterprise Architect 
model (draft T), with the corresponding XML Schemas for File Based 
Exchange. All data structures (including Constraints) have been modelled 
now, and the issue with the ordering of attributes has been resolved.

Feedback from Maria and Peter was discussed. In addition, Peter will 
perform a detailed review of the XML Schemas against the latest Blue Book 
(draft F). It is also the intention to validate the XML Schemas using the 
scenarios from the Services Prototyping (as far as these apply to the File 
Formats data structures).

3.  MAL Blue Book update

The SM&C WG has made available an update of the MAL Blue Book for internal 
review. Roger will check this updated MAL specification against the MP&S 
Blue Book. The draft MAL Blue Book is provided on the GDrive (in Current 
Working Documents, see 
https://drive.google.com/drive/folders/1Q0Xzg6-kUWA4Y27W0MtHvMi--vBHb9hU), 
please send any comments to Roger and Peter.

4. MP&S Blue Book agencies review

Although the MP&S Blue Book is nearing completion, there are currently a 
number of assumptions (in particular regarding the MAL updates) and open 
points (e.g. the update of the XML Service Specification for MP&S, also 
some minor issue to be clarified with the NAV WG). It has been proposed to 
plan for the MP&S Blue Book agencies review anyway in Q1/Q2 2022, not to 
delay the progress on the MP&S Blue Book and its expected publication 
target (end of 2022). The WG agreed with this approach.

The drawback of the above approach could be that any changes to the MAL 
(which still has to go through its own agencies review and prototyping) 
may require an update of the MP&S Blue Book and as such a second MP&S Blue 
Book review may be required. This could anyway be needed in case of major 
comments on the MP&S Blue Book that will result in major changes of the 
standard.

In order to prepare for the MP&S Blue Book agencies review, the following 
steps should be completed (in the next 1-2 months):

a. The Blue Book shall be updated in line with the latest MAL Blue Book 
draft (Roger)
b. The Blue Book shall be updated with possible feedback from the 
Prototyping (ESOC, DLR, Guillermo)
c. The Blue Book and XML Schemas shall be updated based on the review and 
validation of the XML Schemas (Peter)
d. The SANA artefacts (XML Service Specification, XML Schemas) shall be 
made available on the SANA Beta Registry (Peter)
e. The current assumptions and open points shall be listed (Blue Book 
introduction or separately) (Roger)

Peter will check with MOIMS AD if the envisaged way forward by the WG is 
acceptable for CCSDS.

5. AOB 

The next MP&S WG meeting is planned for Tuesday 22 February 2022, 16:00 - 
18:00 CET. Peter to send the WebEx invitation.

Peter
