This works basically the same way as for whole objects, just with a different method to override:
# Find the meta class of objects you want to control the rights for.
# Customize its method ''CustomPropertyGroupRights''. Note that there is a parameter ''metaPropertyName'', so this is about a specific property.#* Now it becomes interesting, because you have many multiple options depending on the degree of detail you want to control the property rights for:
#* '''On meta class level''': If the rights for every property are the same for all instances of a meta class, but differ by user, you should evaluate the relation between the meta class and the user group.
#* '''On meta property level''': If the rights for a property are the same for all instances of a meta class, but differ by meta property and user, you should evaluate the relation between the meta property and the user group. If a meta property is used on multiple meta classes with different rights, you may have to evaluate the relation between: A) the relation between meta class and meta property and B) the user.
#* '''On content object level''': If the rights for every property are the same for the same content object, you should evaluate the relation between the object and the user group.
#* '''On property level''': If the rights for a property depend only on the user, you should evaluate the relation between an attribute on the property and the user group. (An an attribute is needed because you can't relate a property to anything).
# Read the custom rights from the relation data objects connecting the target object and a user group.
# For each combination, create a new instance of ''UBIK.Service.DTO.V240.GroupRight'' and assign both the group and the right.
