Introduction
The European Commission estimates that “The mass adoption of e-invoicing within the EU would lead
to significant economic benefits and it is estimated that moving from paper to e-invoices will generate
1
. Based on this recognition “The Commission
savings of around EUR 240 billion over a six-year period”
wants to see e-invoicing become the predominant method of invoicing by 2020 in Europe.”
As a means to achieve this goal, Directive 2014/55/EU [1] on electronic invoicing in public
procurement aims at facilitating the use of electronic invoices by economic operators when supplying
goods, works and services to the public administration (B2G), as well as the support for trading
between economic operators themselves (B2B). In particular, it sets out the legal framework for the
establishment and adoption of a European standard (EN) for the semantic data model of the core
elements of an electronic invoice (EN 16931-1).
In line with Directive 2014/55/EU [1], and after publication of the reference to EN 16931-1 in the
Oficial Journal of the European Union, all contracting public authorities and contracting entities in the
EU will be obliged to receive and process an e-invoice as long as:
— it is in conformance with the semantic content as described in EN 16931:1;
— it is represented in any of the syntaxes identified in CEN/TS 16931-2, in accordance with the
request referred to in paragraph 1 of article 3 of the Directive 2014/55/EU;
— it is in conformance with the appropriate mapping defined in the applicable subpart of
CEN/TS 16931-3.
The semantic data model of the core elements of an electronic invoice – the core invoice model – as
described in EN 16931-1 is based on the proposition that a limited, but sufficient set of information
elements can be defined that supports generally applicable invoice-related functionalities.
This CEN Technical Specification CEN/TS 16931-3-2 defines the binding of the core elements of the
invoice to ISO/IEC 19845 (UBL 2.1). Other subparts of this CEN Technical Specifications define the
binding method (CEN/TS 16931-3-1) and map the core invoice model to other syntaxes such as
UN/CEFACT XML (CEN/TS 16931-3-3) and ISO/IEC 9735 (UN/EDIFACT) (CEN/TS 16931-3-4).
By ensuring interoperability of electronic invoices, the European standard and its ancillary European
standardization deliverables will serve to remove market barriers and obstacles to trade deriving from
the existence of different national rules and standards – and thus contribute to the goals set by the
European Commission.

1 Scope
This CEN Technical Specification (TS) specifies the mapping between the semantic model of an
electronic invoice, included in EN 16931-1 and the UBL 2.1 syntax (ISO/IEC 19845). For each element in
the semantic model (including sub-elements or supplementary components such as Identification
scheme identifiers) it is defined which element in the syntax is to be used to contain its information
contents. Any mismatches between semantics, format, cardinality or structure are indicated.

4 Syntax binding to UBL 2.1
4.1 Introduction
The Universal Business Language (UBL) is developed by the OASIS open standards consortium. OASIS is
a non-profit, international consortium that drives the development, convergence and adoption of open
standards for the global information society.
UBL is designed to provide a universally understood and recognized syntax for legally binding business
documents and to operate within a standard business framework such as ISO 15000 (ebXML) to
provide a complete, standards-based infrastructure that can extend the benefits of existing EDI systems
to businesses of all sizes. UBL is freely available to everyone without legal encumbrance or licensing
fees.
UBL is widely used around the world for procurement (e.g. ordering and electronic invoicing), sourcing
(e.g. tendering and catalogues), replenishment (e.g. managed inventory) and transportation and
logistics (e.g. waybills, forwarding instructions, and intermodal freight management). UBL provides the
standards for the PEPPOL (Pan European eProcurement Online) network and public procurement
initiatives in Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland,
Ireland, Italy, Netherlands, Norway, Spain, Sweden, and UK (NHS).
Version 2.1 of UBL has been approved for release as an ISO and IEC International Standard, and given
the designation ‘ISO/IEC 19845:2015’.
UBL schemas are modular, reusable, and extensible in XML-aware ways. As the first standard
implementation of ebXML Core Components Technical Specification 2.01, the UBL Library is based on a
conceptual model of information components known as Business Information Entities (BIEs). These
components are assembled into specific document models such as invoice and order. These document
models are then transformed in accordance with UBL Naming and Design Rules into W3C XSD schema
syntax. This approach facilitates the creation of UBL-based document types beyond those specified in
this release.
4.2 Data types
As stated, UBL messages are constructed using reusable Business Information Entities. The (data)
typing mechanism in UBL also relies heavily on reuse of generic components, both within UBL, but also
on the Core Component Technical Specification. Typically this has the following structure:
— The message specification (the invoice XSD) imports schema that specifies all the reusable Business
Information Entities (expressed as XML elements);
6

---------------------- Page: 8 ----------------------
SIST-TS CEN/TS 16931-3-2:2018
CEN/TS 16931-3-2:2017 (E)
— The message is constructed by using these BIE’s;
— Each BIE (e.g. DocumentCurrencyCode) is based on a type with a similar name (e.g.
DocumentCurrencyCodeType);
— Each type is based on one of the UBL “Unqualified Data Types” (e.g. CodeType);
— Each Unqualified Data Type is based on one of the Core Component Types (ccts:CodeType).
In the EN, each element is based on one of the seven specified ‘semantic data types’: Amount, Unit price
amount, Quantity, Percentage, Identifier, Code, Date, Text, and Binary object. Some of these datatypes
have attributes. In UBL, the “Unqualified Data Types” also have attributes, comparable with the
datatypes in the EN.
When making a mapping from the EN to UBL, datatypes and their attributes (if applicable) have to be
taken into consideration. For each element in the EN, it should be clear where to map the contents of
the element, but also how to map the attributes. In most cases, an element from the EN with a specific
datatype (e.g. a Code) is mapped to an element in UBL that has a comparable datatype (e.g. CodeType).
There are however some exceptions. The table below shows what datatype mappings occur in the UBL
mapping, and how often they occur

From (EN) To (UBL) #
Attribute (S) Identifier (I) 14
Attribute (S) Code (C) 1
Attribute (S) Text (T) 1
Only two datatypes in the EN have attributes. For these datatypes the mapping is straight-forward:
simply put the value in the XML element in UBL. For the datatypes that do have attributes (italic in the
table above), a mapping is made to the relevant datatype (attributes) in UBL. The attributes marked in
bold are mandatory.
These mappings are presented below.
Table 2 — UBL attributes
EN UBL
Amount AmountType
   currencyID
Unit Price Amount AmountType
   currencyID
Quantity QuantityType
Percentage PercentageType
Code CodeType
Identifier IdentifierType
 Scheme identifier  schemeID
 Scheme version identifier  schemeVersionID
Binary Object BinaryObjectType
 Mime Code  mimeCode
 Filename  filename
The amount data type in UBL has a mandatory attribute called currencyID. This attribute is used to
define the currency of the amount. In the EN, the currency of the amount is defined as a single business
term, the BT-5 and defines that only one currency shall be used in the Invoice except for the Total VAT
amount in accounting currency (BT-111) in accordance with article 230 of Directive 2006/112/EC on
VAT. In consequence, every currencyID attribute in the UBL AmountType elements shall map to the BT-
5 Invoice currency code except for the currencyID in /Invoice/cac:TaxTotal/cbc:TaxAmount that can
mapped to BT-5 or to BT-6 if exists.
The EN 16931-1 semantic data model uses semantic data types that consist of more than one
information entity. For instance with the Identifier data type it is possible to accompany the content
with a corresponding Scheme identifier. The EN 16931-1 does not apply unique identifiers to those
additional entities. In order to clearly identify those components in the following syntax mapping, those
additional entities are numbered by adding a dash and an additional number to the original ID. For
example the Scheme identifier that corresponds to the Buyer identifier (BT-46) gets the unique ID BT-
46-1. As UN/CEFACT XML fully supports the codelists referenced by the Semantic Data Model (SDM)
the corresponding codes to the semantic requirements of the latest published lists can be used without
any additional mapping.
