Re: [paws] JSON encoding

[Benjamin A. Rolfe]

The ability to include uncertainty seems like it may be important.  I can imagine as protection criteria evolve, we may see criteria based on relative proximity to protected devices, and position uncertainty is important for figuring that out. We also see it specified in the exchange of information between dependent devices and the internet connected device (802); Proposed standards in 802.11 and 802.15 under development use an encoding based on RFC6225, which includes uncertainty, and it could be quite handy if it is obvious how to map from this form to whatever PAWS transports. So yes, use one that supports that. It'd be even better if it can be elided when not needed to save bits on the air. -Ben <as individual> Use 5194, which is based on OGC's GML in preference to 6350.  Among other things, you may need the ability to encode uncertainty of location. You could consider the Geo URI (RFC5870), but it has the same uncertainty problem.

The other one is vCard, RFC6350. There is a so called xCard, RFC6351, the xml representation of vCard, but again, I have not found a JSON encoding for vCard. vCard seems to be able to handle contact information, schedule, etc, but there are obviously other data fields, like antenna parameters, which need to be defined in PAWS.   First, I’d like to get some opinions on whether the reuse of the data structures defined in the above two RFCs is generally considered a good idea or not. If we want to reuse them, we’ll need to define a JSON encoding for those. The alternative is to define the whole data structure with JSON encoding in PAWS.   I’d like to hear opinions on which way is more feasible.   -          Gabor     _______________________________________________ paws mailing list paws@ietf.org https://www.ietf.org/mailman/listinfo/paws _______________________________________________ paws mailing list paws@ietf.org https://www.ietf.org/mailman/listinfo/paws
