can mint two ids for same object

[bheavner]

If I mint a minid two times in a row (same checksum, etc.), the server mints new minids both times - shouldn't the server refuse to make a new minid if the entity already exists?

Here's my second minted minid for the same json:

I thought the intention was to allow different users (identities) to create minids for the same object. It does seem redundant to allow the same user/identity to create a new minid for an object that they have already created one for. They should be updating that existing identifier rather than peeling off a new one. Maybe this is just a bit of missing logic on the backend?

I thought there was a check somewhere to see if the checksum already existed. It'd make sense to me to have a 1:1 mapping of checksums to minids, but a minid can have many locations... location-parsing is up to clients for now, I think.
