-- Discussion of Comment/Use case from Enrico; use case not clear by participants; Enrico not there to precisely explain, so decision not to discuss now, but to postpone this discussion and have Enrico explain problem / use case in more detail on mailing list; 
-- suggestion from Francois to document progress & current issues in design team so that before call people are up to date
-- plan to make progress with "footprint" is to go through use case from Emile & Anne; Emile describes use case; 
-- Jan: informal description of use case uses "country" as footprint, does that make sense, i.e. geographical location? discussion on geographical location, Emile: makes sense, Stefano: makes sense; Stefano: problem is that there is no universal format for geographical location; Emile: there is ISO format for regions; Stefano: what about relationship between geographical regions, e.g. distance between regions; 
-- Jan: for reachability, what else is on the table besides IP-prefix, ASN, geographical region?
-- Emile mentions ISO 3166-2; Rich: were would that be encoded?
-- Rich: let's go through use case with the footprint types on the table; Jan: indeed, that is the plan; question is where in detail some types of information are problematic or better than others, on a high level all the reachability types of information on the table make sense to support the use case;
-- Jan: seems to be agreement that all reachability types on the table are useful to support use case; Jan: so what about resource type of information?
-- Stefano: should we go into more detail about the information types we definetely agree on (i.e. IP-prefix and AS-number)? 
-- Jan: what about deriving requirements for conveying these types of information?
-- Rich: what be interesting to derive rationale and requirements for resource type use case
-- Jan: summary is to digg deeper into requirements for agreed reachability information types and to find out more the use case behind the resource type of information and what the requirements for conveying this type of information are
