The following pages describe the elements within the eInvoicing Semantic Model in tabular form. These have been mapped to the UBL 2.1 Data Model and the equivalent terms mapped. (Note – The methodology and terminology used is taken from CCTS (UN/CEFACT, 2003)).

The rows with a pink background denote aggregations of Information Elements (ABIEs).

The rows with a white background denote basic Information Elements (BBIEs).

The rows with a green background denote associations between aggregations of Information Elements (ASBIEs).

The occurrence (cardinality) of these Information Elements is given as one of the following:

• 1 – means the Information Element is mandatory and must have only one occurrence;

• 1..n – means the Information Element is mandatory and may have more than one occurrence.

• 0..1 – means the Information Element is optional and if used may have only one occurrence; or

• 0..n – means the Information Element is optional and if used may have one or more occurrences;
