Lion’s got quite a fancy board that he writes on.
Lion has explained why he is not active on CommunityWiki:
Two types of FS:
(A) (a link can only have exactly two entities involved) Discussion: link between <caller:Person> <calee:Person> DiscussionPlace?: link between <Discussion> <Location>
(B) (a link can have at least one entity, possible multiple) Discussion: link between <caller:Person> <calee:Person> <location:Location>
CiprianCraciun? and Lion talked quite a bit about data modeling, which was written about afterwards here: https://scratchpad.volution.ro/ciprian/992c7f2944456f18cdde77f683f49aa7/1ab930b7.html
