Hello Andrea, 

Can you help me understand why you think that the scope of delivery context is restricted by giving an example of a characteristic that would be part of device description and would not be part of delivery context? 

My understanding of DDWG's concept of device description was that it was primarily to support content adaptation, or at least for delivery of web materials to a device. That is the same scope as delivery context is meant to be, so it seemed reasonable to me that one could be a subset of the other. If there are characteristics that are part of device description that are not part of delivery context, then my assumption is clearly false.

Best wishes

I'm jumping in late, even later than Jo, who apparently regained the lost time very quickly.
I have read all the posts of course and have my opinion.

I don't understand why we are restricting the "device description"
definition to the delivery context. It should be a more general description that may cover ANY aspect of the device and that in our specific case is limited to the delivery context.

I think that the definitions that actually matched my idea of DD are the earlier ones. This is my definition of device description:
a collection of attribute-value pairs that detail the features and capabilities of a device

In my understanding when the term "set" was used it was meant as a collection while it was later interpreted as a "collection of devices matching a set of parameters". This means that we went from something that is supposed to describe all the details of a single device to a "filter" that will return a list of devices.

I would like to first define what a single description is and then we can talk about how you can group descriptions.
