Hi Mehran,

I’ve checked the new version of blue and yellow books and I see all my previous comments have been

Good work!

Best,

Tomaso

Dear Erik, dear Tomaso, 

Please find attached the updated MAL book and the corresponding YB with the updates performed in 
response to the conditions you had raised.
Please find below, in blue the resolution of your raised conditions. 
I would be grateful if you could confirm that your condition is satisfied with the implemented changes.

Best Regards
Mehran

Erik Barkley (Approve with Conditions):  
1.	Pg 6-1, In Sections 6.2 and 6.3.1, the SANA Registry URLs are broken/return HTTP 404 error -- 
please correct.
>> SANA registry was updated with the help of Tom Gannett and Julien Bernard with the missing 
files. Please note that due to technical restrictions of SANA, the files are not accessible prior to 
publication of the book. After the publication, they will be accessible under the correct link that is 
used in the book:   https://sanaregistry.org/r/moschemas 
Before the publication the files are available here: https://beta.sanaregistry.org/r/moschemas/

2.	RID Spreadsheets: Please indicate final dispositions in spreadsheets -- for example, RIDs CNES-
30, CNES-33, DLR-026, ESA-CC-002 and others indicates "Discuss with WG" or "Needs discussion 
in the WG" as the Disposition.  In some cases, it is possible to infer that the RID was accepted by 
the additional comments, but in other cases there is just simply "Done" for the "Resolution" and 
it is not clear if the RID was accepted or rejected. 
>>  Please find attached the updated Excel files with the final resolution for all RIDs.

Tomaso de Cola (Approve with Conditions):  

1.	There is a problem with the numbering of normative references, but this can be easily fixed.
>>Tom has corrected the normative reference numbering problem in the source document. (see 
also his email on 13.02.). 

2) Section 8 is about a conformance matrix, but isn't this object of Annex A about NPICS?
>> Indeed, the matrix was an unnecessary repetition in Section 8 and in Annex A3. Thank you for 
spotting it. We have removed Section 8 and kept the Annex A3. 

3) NPICS matrix in A-3 and following is not aligned with what provided in CCSDS A20.1-Y-1. 
Practically speaking I'd have expected to find a numbering for all identified features/options, which 
is not indicated. Also, the reference to the location where an option/feature is specified missing. 
>> A3, A4, and A5 provide the list of the MAL interaction patterns (these are all mandatory), the 
MAL data types (all mandatory) and the MAL errors (all mandatory). They are the core constructs 
of MAL.These are the items that must be present in a functioning MAL, so not really features in a 
specific place. We have add numbering on A3, A4 and A5 to make it clearer. Also in the YB we 
have added an explicit section 7 to provide a clear mapping to the tests (see the answer to the 
point 4).

4) The interoperability testing report (yellow book) apparently does not develop specific tests to 
show the correct implementtion of the options/features identified dntified in the NPICS of the 
compaionin drat blue book. eluw book. 
>> YB has been updated. We added a dedicated chapter 7 for mapping of the tests as requested.
