Linked Identifier data (CSV) attributes

This section provides the following information about each attribute of the CSV product:

Name and Description

The name of the attribute and what it is describing.

Type

The nature of the attribute, for example a numeric value or a code list value.

Multiplicity

Describes how many times this element is expected to be populated in the data. An attribute may be optional or mandatory; these are denoted by:

• ‘1’ – Mandatory - There must be a value.

• ‘0..1’ – Optional – If populated a maximum of one attribute will be returned. These values may be used in combination.

CONFIDENCE

Confidence value based on a comparison of feature dates between the two source features. Can be one of:
