<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">thank you for the updated Green Book, which reads very well and provides a significant improvement compared to our old version. I circulated the draft to my
colleagues and feedback was largely positive. These are the comments by my co-workers and me:<o:p></o:p></span></p>

to standardization or for services intended to be used intra-agency only. Thus, MO provides benefits even when leaving the realm of standard services.<o:p></o:p></span></p>

however, it would be nice to use MO for administrating these data exchanges, e.g. the consumer/provider could negotiate, using MO/MAL, to provide the data via an MO-independent connection (similar to the File Services, 9.2.6., using an ftp connection).<o:p></o:p></span></p>

Please find below the link to the latest draft of the MO Concept Green Book for review:<br>
<br>
<a href="https://cwe.ccsds.org/moims/docs/MOIMS-SMandC/Draft%20Documents/Concept%20Green%20Book/Green%20Book%20Outline%20R5%20Feb%202019.docx?Web=1">https://cwe.ccsds.org/moims/docs/MOIMS-SMandC/Draft%20Documents/Concept%20Green%20Book/Green%20Book%20Outline%20R5%20Feb%202019.docx?Web=1</a><br>
<br>
Please could people provide comments etc by 8th of March in three weeks time. <br>
<br>
The contents of the book is 95% complete, just the future directions section to be expanded on, if people could suggest content for that as part of the review that would be very helpful. It is also not in official CCSDS format, but that is relatively easy to
add at a later date.<br>
<br>
I think Peter has done a great job in writing this, however it has taken far longer than we had hoped therefore I would like to suggest that I take over the editing/updating of the document from this point forward. If there is an issue with this suggestion
please let me know otherwise I will assume that it is acceptable.<br>
<br>
Best regards,<br>
Sam.<o:p></o:p></p>
