#tags_for_cloud(limit = 50, bands = 6) ⇒ Object

note varying logic here: tag clouds are used differently when describing a group. if only one object is relevant, all of its tags will be equally (locally) important. Presumably that cloud should show global tag importance. If several objects are relevant, either from a list or a tree of descendants, we

probably want to show local tag importance, ie prominence within that list.

end

#with_children ⇒ Object

the family-tree builder works with generations instead of individuals to cut down the number of retrieval steps
