Instruments

The territorial information contained in uThings is stored in separate containers or “Instruments”.
The Instruments can have three functions:

  • Inventory: Instruments that contain all territorial objects, form the main data core of uThings
  • Operator: These are instruments used to contain operations for updating the Inventory Instruments
  • Base: they are Instruments that serve as a template of Attributes for other Instruments, so that all the Instruments of a Administrative Unit use the same set of Attributes to qualify their Entities.

In uThings we have grouped the Instruments according to the type of territorial objects it contains, forming four purposes:

  • Planning: it contains all the ordination objects that determine the territorial model defined by the Planning Instruments. The objects of ordination usually correspond with polygons or closed geometries delimited by the Instruments with different purposes closely linked to the legislative formulation of each territory.
  • Rights: it contains all the existing real rights over the territory, usually corresponds to those that have a more marked urban effect: Domain, Use or Activity, Score, Retract, Ford, Surface, Census, Administrative grant, Construction … Although May be extended to the Usufruct, Mortgage, Enfiteusis or any other defined by the Base Instrument or some other Instrument and that has urban importance or for the management of the Public Land Patrimony.
  • Objects: contains all physical objects that form the urban territory and are subject to public authorization and inspection.
  • Obligations: Territorial objects are subject to duties of different types: Urbanization in term, Building in term, Assignment, Conservation, Maintenance … Duties that are established by many different instruments, sometimes with a specific spatial delimitation and normally related to Entities already defined In other Inventories.

Each Administrative Unit, depending on its extension and urban activity, may contain thousands of Instruments. For the purpose of its better ordering, visualization and selection it is convenient to establish a hierarchical classification mechanization based on the principle that every Instrument is assigned a “Parent Instrument”, so that it is possible to establish a tree structure.

Usually this makes more sense in the Planning Inventory, where it is usual for some instruments to be formulated as development or modification of others.
