Re: [paws] Review of draft-ietf-paws-protocol-12 (by the other APPAD)

["Luzango Mfupe" <[e-mail]>]

Hi Vince,
 
Thanks for prompt clarifications however, my suggestion is that the
data type of vCard fragments (the device owner part and the device
operator part) as a whole should be explicitly stated in section 5.5.
Here I am not talking about the data types of individual parameters
inside the vCard itself. This will indeed help to preserve the integrity
of card formatting when they are being parsed by different applications
as well as promote uniformity in different PAWS implementations.
 
Kind Regards,
Luzango.

Hi Vince, Folks,

It seems the issue of adding the single-resolution bandwidth example
slipped off the cracks some how as it was supposed to be included in the
current draft.


Please see the first example in Section 5.11, which was added based on
your suggestion.



Today I am presenting another burning issue relevant to the following
Sections:

SECTION 5.5 DeviceOwner
SECTION 6.4 Example Encoding Device Owner vCard

Can you please elaborate how the device owner jcard/vCard fragments
should be handled within the JSON registration request message body;
what primitive type(s) should be applied( i.e, String, int etc...).
Apparently there is already a great deal of confusion in this area as
some would thinks the card fragments should just be sent as-it-is in an
array format with the rest of the JSON registration request body

To the best of my understanding jcards are supposed to be written as
String primitive types this allows to preserve the formatting when they
are parse/read by the spectrum database/server or any other application
that would wish to extract the contact information in a standardised
format. 

Section 5.5 is silent on the definition of vCard data type(s), while
the example provided in Section 6.4 shows the vCard in an array. 

May I suggest that we should also explicitly state the data type of
jcard similar to the way we have defined data types for other aspects
throughout the document (e.g., In Section 5.2 Device Descriptor)...In
doing so this will clear any future confusions in the implementation of
our standard.


Actually, Section 6.4 is the jCard representation and was intended to
provide the clarification you're asking for.
Perhaps it needs a better intro sentence?

Since Sections 4 and 5 define new data models for PAWS, we provide a
mapping from those data models to JSON.
On the other hand, we are not redefining vCard and jCard, so it seemed
redundant to repeat their definitions.

Kind Regards,
Luzango.

Hi Vince, Folks, 

I am glad to see things are moving to the right direction and hopefully
soon we will finalise this work.


I just found some few not very critical issues that needs some fixing
in in my opinion:



5.11. Spectrum


Here the document talk about the FCC and OFCOM/ETSI spectral profile
presentation requirements (i.e, power levels over a set of frequency
ranges. However, there is only one type of example (OFCOM/ETSI specific)
that is provided throughout the document. I think we need to add another
set of example that is FCC specific. 


Would something like this below suffice for the FCC specific example?

“resolutionBwHz”: 1e5,
“profiles”: [
{
"Hz": 5.18e8,
"Hz": 5.24e8,
“dbm”: 24
] },






Ah. I see. We can add a single resolution-bandwidth example for
completeness.
