Tom,
I know the goal was to try and publish the Prox-1 PICS before the Fall meeting. But on the other hand, it would be good to go through them as a WG to ensure we are all on the same page with them for compelteness across the board.
Gian Paolo – are we obligated to publish the PICS (and therefore all three Prox-1 books) before the Oct. meeting, or can we wait until after?
I'd like for the WG in person to have one more look at it at the Fall meeting.
By the way, please send out your official copy of all the draft Prox-1 PICS to us, so that we make sure we are all in sync.
Thanks!
Greg

Greg:
That would push publication of the Proximity books into late November or December (or later). Did the review reveal issues that can't be resolved without a face-to-face meeting?

Matt,
Got it.
I also need to add the Proximity-1 Space Data Link PICS Proforma discussion to the SLP WG Agenda.

Greg,
I agree with Gian Paolo on his points on section 5.4.
I think we should have:
- DLL-64 / 5.4.2.4 Mandatory if DLL-62 Supported
Tom will need to advise on how we represent that.
I would also suggest that we delete: (notional)
Hope to see you all in Texas.
Cheers, Matt.

Greg,
Just about DLL-1.
DLL-1 should be removed if it refer to section 3.2.
Making DLL-1 to refer to 3.2.1 (instead of 3.2) makes the second comment superseded.
I am not sure I agree about your view of section 5.4 and I would rather use "conditional items" also because as far as I see this is the only case (i.e. no big burden implied). However we can go Pink with the present form (except the corrections you agreed) and discuss the matter in San Antonio to generate RIDs (if needed).
One more comment: DLL-60 says "Time Correlation Process (notional)".
The term notional is mentioned only once in the document (i.e. here).
Should its meaning in PICS context be clarified (or alternatively deleted)?
Ciao
Gian Paolo

A few very quick comments.
Of course there may be more for similar cases.

A2.2 PICS
Should DLL-1 better refer to 3.2.1 instead of 3.2?
** Yes 3.2.1 **
DLL-1 should be removed as individual subsections of 3.2 are addressed and moreover DLL-1 as it stands now is incorrect/confusing as it includes also options?
** We need users to comply with both 3.2.1 and 3.2.2. The subparts of 3.2.2. are useful to see because they contain valid values associated with these parameters. **
Why the description of Option 1 is with lower case o (i.e. o.1 instead of O.1 as in the table)? ** I think it was a typo. It was corrected as all capital letters in my version **
Why DLL-61 is in bold? (this is not the only one in bold...) ** I think this is Tom's way of showing a heading. **
Is it correct to mark all the items within e.g. 5.4 as optional? ** Yes that was deliberately done by the WG **
If you read section 5.4, it contains mandatory requirements and options.
This was actually a case for conditional items as follows:
- DLL-63 / 5.4.2.1 Optional
- DLL-64 / 5.4.2.4 Mandatory if DLL-62 Supported
Is it correct giving up about conditional items in PICS? ** In this case, yes **
Moreover
DLL-61 / 5.4 should not be listed as the individual requirements are listed
DLL-63 should refer to 5.4.2.1 and not to 5.4.2 ** I agree, DLL-63 refers to 5.4.2.1 **
As section 5.4 is written, it is not visible that this feature is optional ==> should 5.4.1 be made optional? **yes **
PICS take - as expected - several pages.
Why not shortening some cases as e.g. DLL-52 / 5.2 ?
In other words why not having only a row for DLL-52 and removing the 8 following rows?
Alternatively why not indenting the following 8 row and using identifiers as DLL-52.x?
** Up to Tom Gannett how best to deal with indexing or showing subsets of information within the PICS **
** We could shorten the DLL PICS, however I tried to strike a compromise between the shortest PICS Proforma possible vs conveying some redundancy that helps the user check through the items by listing the key ones in detail. If I hide too much information, people might have the tendency to forget about it. Explicitly listing it (but not regurgatating the entire text) seemed to be the best compromise **
**Thoughts from other SLP WG members ??? **

Dear SLP WG members,
Tom Gannett has provided us now with a pre-approval version for the CESG of the Proximity-1 Space Data Link Protocol.
Please review the attached documents and send me and Tom any comments you have (redlines of the clean version would work, if you have the bandwidth to send a 20 Megabyte file !) to me and Tom by Sept. 13.
There are two files in the CWE directory below. One is a red-lined version so that you can see the changes made and also a clean version.
