owned resources may not be announced or visible universally.

existing data sources deeply suck.  rir source data are in different
formats, owner identies are not even unique in one rir (how many names
does goog have in arin?), let alone coordinated across rirs, much
historical data is missing, ...

dual ownership is needed for transfer.  so i am thinking along the lines
of an aged report of cert conflicts.  maybe "bob and alice have both
owned 42.666.0.0/15 for 77 days."  

of course this begs the issue of irs not having unique single IDs for
bob and alice.
