Base Model

Definition

Abstract class that appends common fields

__init__(*args, **kwargs)
class inspire_eu.models.abstract.Identifier(*args, **kwargs)[source]
Definition

External unique object identifier published by the responsible body, which may be used by external applications to reference the spatial object.

Description

NOTE 1 External object identifiers are distinct from thematic object identifiers.

NOTE 2 The voidable version identifier attribute is not part of the unique identifier of a spatial object and may be used to distinguish two versions of the same spatial object.

Parameters:

  • local_id (CharField) – Local id. A local identifier, assigned by the data provider. The local identifier is unique within the namespace, that is no other spatial object carries the same unique identifier.<br />NOTE It is the responsibility of the data provider to guarantee uniqueness of the local identifier within the namespace.

  • version_id (CharField) – Version id. The identifier of the particular version of the spatial object, with a maximum length of 25 characters. If the specification of a spatial object type with an external object identifier includes life-cycle information, the version identifier is used to distinguish between the different versions of a spatial object. Within the set of all versions of a spatial object, the version identifier is unique.<br />NOTE The maximum length has been selected to allow for time stamps based on ISO 8601, for example, “2007-02-12T12:12:12+05:30” as the version identifier.<br />NOTE 2 The property is void, if the spatial data set does not distinguish between different versions of the spatial object. It is missing, if the spatial object type does not support any life-cycle information.
