Many thanks for the helpful comments! I updated the green book according to the comments from both Richard and Felice. The new version is checked in at github and at CWE in the SOIS-APP Spring 2015 meeting materials.<br />
<br />
Here is the list of issues that I know about that could benefit from discussion:<br />
<br />
P 5-32<br />
Using encoding in arguments:<br />
Commands hide PDU's; parameters expose them. Commands need a clear explanation.<br />
Do they not belong in subnet SAP, but are OK in DVS and DAS SAPs?<br />
<br />
P 5-35<br />
Segmentation:<br />
How do you describe subnet parameters? Are command arguments needed to specify them?<br />
<br />
P 5-44<br />
Distribution of calibrators over vectors.<br />
Also, implicit invocation of calibrators has not yet been decided.<br />
<br />
P 5-45<br />
"native" flag:<br />
SDU corresponds to a PDU at device. We should describe the PDU's somehow. Do we neet native attribute on containers?<br />
<br />
P 5-56, 5-57, 5-58<br />
Adapting device to software bus. Is MTS an alternative to DAS/DVS? It's not in schema.<br />
Mapping variables inbound and outbound through adapter EDS.<br />
State machine responds to inbound, activity sends outbound through adapter EDS.<br />
How do you combine EDS's inside the onion? More device? or more component?<br />
<br />
The "executive summary" attempts to combine the functions of the DoT and the EDS schema.<br />
Also, the use cases that are possible, just using data interface information, go beyond avionics.<br />
<br />
Whether to remove figure 3.<br />
<br />
How to phrase statement about a space agency that acts as its own supplier.<br />
GSFC seems to do this sometimes.<br />
<br />
Section 4 use cases. Should some be removed?<br />
<br />
Standard interfaces.<br />
<br />
Device Driver development – this can be filled in from ESA’s “Adoption of EDS and Device Virtualisation” project outputs<br />
<br />
Software component development – this can be filled in by NASA/GSFC from their adoption of MTS EDS for cFE<br />
<br />
Another topic in section 4.2.2 is the interchange of information between model-based system engineering tools and EDS's, for <br />
<br />
which some initial R&D has been done at NASA's Johnson Space Center<br />
<br />
TBD AIT, simulators, test equipment, MCS databases –some of the stuff Stuart Fowell and Stewart Hall have put together for the <br />
<br />
EDS business development slides could be turned into text.<br />
<br />
Device development – this can be filled in from ESA’s “Deploying Plug-and-Play Avionics” project or at least the proposal<br />
<br />
1553 subnet SAP<br />
<br />
xpointer schemes<br />
<br />
Are variable maps needed? If so, when do they function? Is an activity map one that does more than just copy?<br />

<font face="sans-serif" size="2">Dear Ray and all,</font><br />
<font face="sans-serif" size="2">during the course of this week I also reviewed the EDS & DoT Green Book.</font><br />
<font face="sans-serif" size="2">Please find attached a handful of comments.</font><br />
<br />
<font face="sans-serif" size="2">In general, considering that at the last meeting we just had the table of content, you have done an impressive job!</font><br />
<font face="sans-serif" size="2">I think it is a good idea to filter out offline/by email the comments easy to solve and to highlight the important ones requiring discussion during the Spring meeting.</font><br />
<font face="sans-serif" size="2">It might also be useful to list the "open points" (marked in red in the book) requiring additional work.</font><br />
<br />
<font face="sans-serif" size="2">Best regards,</font><br />
<font face="sans-serif" size="2">Felice.</font><br />
