Hi Christian

I completely agree that explanatory notes would be helpful, and I will aim to add some to the Wiki Definition [1].

You ask if the term "some context" was used deliberately and the answer is "yes". As Rotan points out, he included only part of the definition in his summary. The full definition, which as I say is at [1], actually says:

"A device description is a formal definition within some context of the named attributes and their permissible values [which may take the form of lists, ranges, or other patterns] which are applicable to entities of interest in that context."

"In general that entity is a device in the context of interest."

"In the DDWG that entity is something that can fulfil the role of device as defined in the DI Delivery Context."

The reason for putting it this way is that the meaning of "device" can be different according to the context you wish to discuss. As far as the DDWG is concerned the context (and hence the properties of interest) is delivering the Web to mobiles. So a device is something that is capable of accessing the Web, from our perspective.

However, we don't want to exclude the use of the same framework in different contexts. For example, you might want to describe the properties of mobile RRS Readers. We'd like you to use the same device description framework to do that, albeit that your meaning of device and the properties that are of interest are not exactly the same as our meaning of device and the properties that are of interest to us.

I agree that explanation is needed and as I say will add some text at [1] to elaborate. If you have a suggestion as to how the definition itself could be made clearer I'm sure the group would like to hear it.

Thanks for your comments.
Jo
