Re: Draft roadmap for new work items

Hi Dave,

I can do the proposed call next Thursday ...

Regarding the new work items for the group these are my comments:

+I'm missing a work item on DIAL v2. Regarding this I think we should 
define a roadmap for DIAL and a plan for DIAL v2 which is IMHO something 
totally separated from the Policy based Layout spec. I'm willing to work 
on this "DIAL roadmap".

+ For policy based layout or Device Independent Layout, as I pointed out 
recently I would like to participate and edit documents of this task 
force. We can contribute with some ideas coming from the MyMobileWeb 
project and I will be more than happy to analyse or adopt good proposals 
coming from existing solutions of group members. I will be on vacation 
from August 20th to September 10th. After vacation I can start working 
on that

+ Delivery Context Ontology. I have been providing feedback to Rhys 
since the beginning of this work item in the context of the DD Group. In 
the context of the MyMobileWeb project, in which we plan also to create 
an ontology for semantic content adaptation, we have been analysing the 
current version of the DC ontology and we will submit to the group some 
comments during the next couple of weeks.

Have a nice weekend

Best Regards
