basic administrative unit
administrative entity, subject to registration (by law), or recordation [by informal right , or customary right, or another social tenure relationship], consisting of zero or more spatial units against which (one or more) unique and homogeneous rights [e.g. ownership right or land use right], responsibilities or restrictions are associated to the whole entity, as included in a land administration system
Note 1 to entry: 'Unique' means that a right, restriction, or responsibility is held by one or more parties (e.g. owners or users) for the whole basic administrative unit. 'Homogeneous' means that a right, restriction or responsibility (e.g. ownership, use, social tenure, lease, or easement) affects the whole basic administrative unit. For a restriction, zero parties are a possibility.
Note 2 to entry: A basic administrative unit may play the role of party, e.g. when the right holder is a basic administrative unit (and not a person or organization).
Note 3 to entry: A baunit should get a unique identifier when registered, or recorded.
Note 4 to entry: A baunit can consist of zero spatial units, when a registry exists, and not a cadastre.
Note 5 to entry: Restrictions and responsibilities can be associated with their own baunits, each with their own type of spatial unit.
EXAMPLE A condominium unit comprising two spatial units (e.g. an apartment and a garage), a farm lot comprising one spatial unit (e.g. parcel of land), a servitude comprising one spatial unit (e.g. the road representing the right-of-way), a land consolidation area, or a right-of-use unit with several right holders and restricted objects.
