Adding labels to "uri" types

[Akillus]

Hello, congratulations for the great work!
I didn't find a way to associate a label to an URI when the type is "uri", as for instance in this case:

'crm:P2_has_type': [{'type': 'uri',
'property_id': 456,
'property_label': 'has type',
'is_public': True,
'@id': 'http://localhost:8887/omeka/s/4ch-kb/item?resource_class_id=327',
'o:label': 'Person'}]

Apparently, your functions only accepts 1 parameter/value, how can I set the "o:label" property associated with the URI in this case?
Thank you in advance for your reply.
