[the cat] --[sat on]--> [the mat]
            [an hour] 

could currently be broken down something like :

[sat on] --[subclass]--> [sat on for an hour]  

[the cat] --[sat on for an hour]--> [the mat]

[sat on for an hour] --[cardinality]--> [1]

but it seems less clunky to say :

[sat on for an hour] --[instanceOf]--> [sat on]

[the cat] --[sat on for an hour]--> [the mat]

but then is [sat on] in the first figure really an arc?
hey-ho ;-)
