Jane is correct, there is a long standing action to remove the BOF and update
the charter to encompass the P&P activity. Let's include this as a specific
tracked action.

Hi Stuart,
So that you can close some actions promptly, here are my responses. Note
that Bill Horne has taken over as GSFC Standards manager, so any
process/managerial/voting questions should be directed to him.
#1.3 – This comment was made over a year ago. If memory serves me, there was
an ESA programmatic issue which kept the PnP BOF from becoming its own
WG...something along the lines of resources for a “new” WG vs. keeping an
existing one going, hence the “initial” work is being done under SOIS APP.
Chris may recall better than I. Perhaps I’m mistaken. So I’m not sure
this is still a valid comment.
As a side to the primary part of the comment, I also suggested that if
someone looking in from the outside wanted to know if there was any PnP work
going on in CCSDS, they would only find the BOF description page but no info
on the real work being done. Hence it might be advantageous to the WG to
somehow get that info, or wording, inserted somewhere in the SOIS public
domain.
#1.12 – I am no longer the one to ask. I did see in an e-mail that all
comments were due March 18th to Glenn. I myself did not review it, but if
Glenn did not solicit or receive any comments, then by default the book goes
forward.

Hi,
Attached are the minutes from Tuesday SOIS Plug-and-Play Telecon #1.
Those on the cc list, please can you check that you are in the SOIS-OPP
mailing list.

Subject: SOIS Application Support Services WG - Plug-and-Play Work Plan
CCSDS SOIS-APP Plug-and-Play Work Plan
Building on issued standards for subnetwork services, one of the major
goals of this group is to agree a coherent architecture for
plug-and-play of onboard devices based on use cases and requirements
and to produce and agree a set of standards to allow interoperable
plug-and-play implementations.
Aims
The main aim of the SOIS-APP group’s work on plug-and-play is to
publish standards for:
A coherent onboard plug-and-play architecture documented in the
SOIS Green Book
Services for carrying out plug-and-play activities and
interfacing with plug-and-play devices in the form of Device
Enumeration Service (DES) and Device Virtualisation Service (DVS)
Magenta Books (no changes have been identified as being required
to the current Device Access Service Magenta Book).
A specification for a SOIS Electronic Datasheet (EDS) standard in
the form of a descriptive book and an XML schema – Blue Book?
A specification for the mapping from an IEEE 1451.0 TEDS to a
SOIS EDS – part of EDS Blue Book?.
A specification for the mapping from an xTEDS datasheet to a SOIS
EDS. It may well be that the xTEDS datasheet is just one section
of a SOIS EDS. A translation could be specified as an XSLT –
part of EDS Blue Book?.
A specification for the dictionary of terms (DoT) – part of EDS
Blue Book but see below?.
A specification for the process of updating the DoT. This needs
to be a relatively quick process as, particularly in the
beginning, the DoT will need to be updated frequently – under
control of SANA?.
Template datasheets for each of the specified device classes –
part of EDS Blue Book or separate?.
A process for the allocation of unique identifiers, if required –
under control of SANA?.
Work Plan
These are roughly, but not exclusively, in order. Some overlap will be
necessary.
1. Detailed investigation of IEEE1451.0 including a description of
all elements to ensure a strict superset. Lead?
2. Detailed investigation of draft AIAA SPA standards to align
DVS-level datasheet section and DVS/DES service interfaces where
applicable. Lead?
3. Propose an initial EDS schema. Lead?
4. Specify electronic datasheets for approximately 20-30 existing
devices to ensure compatibility and refine EDS schema. These
devices must be selected for both breadth (coverage of device
classes) and depth (variation within a device class). This
process is to ensure that the EDS schema is sufficiently flexible
to be able to represent most devices, and to build confidence in
the SOIS plug-and-play approach. Lead?
5. Align dictionary of terms with SPA/AIAA CDD. Lead?
6. Merge DVS service interface-level EDS with xTEDS including
DoT/CDD merge (political as well as technical). Lead?
7. Prototype DVS and DES for design-time and run-time adaptivity use
cases. This should use the full range of specified electronic
datasheets. Lead?
8. Refine DVS to accommodate temporal and non-functional issues.
Lead?
9. Develop prototype tool chain including IEEE 1451.0 TEDS import
and SPA/AIAA import/export. Lead?
10. Refine DVS and DES and align interfaces with SPA/AIAA.
Lead?
11. Carry out survey of existing devices (probably combined
with above) to permit the definition of template device EDSs (for
device classes). Lead?
Progressing the Work Plan
To progress through the work plan, we aimed to have fortnightly
teleconferences, limited to 1 hour and at a regular time, to progress
this. Each work item should be allocated an owner, who will commit the
time to guide the item through to completion (it is anticipated that
others will need to contribute, even if it is only in the form of
reviewing).
A Doodle survey has been set up (http://www.doodle.com/4kdtstb9ayrgc2fm
) <http://www.doodle.com/4kdtstb9ayrgc2fm> to agree day of week when
most people can attend on a regular basis. This will also give us a
basis of those who wish to participate (those who respond to the
survey).
Agenda of PnP Telecon #1:
1. Agree work plan and item owners
2. Item 1 on the work plan.
