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 [3] 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 [3], 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 16931-3-3 defines the binding of the core elements of the
invoice to the Cross Industry Invoice of UN/CEFACT XML. 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 ISO/IEC 19845 (UBL 2.1) (CEN/TS 16931-3-2) and ISO 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 document specifies the mapping between the semantic model of an electronic invoice, included in
EN 16931-1 and the Cross Industry Invoice in the UN/CEFACT XML syntax. 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 the UN/CEFACT XML Cross Industry Invoice D16B
4.1 Introduction
One part of the basis for the European Core Data Model are the CEN MUG CWAs which are a subset of
Cross Industry Invoice (CII). UN XML standards are developed within UN/CEFACT. This guarantees an
international focus, openness in the process and free usage, as this is the mission of UN/CEFACT and the
2
policy of UNECE as a global standardization body . For all published specifications and standards the
Inetelctual Property Rights (IPRs) are owned by the UN and as such are open for free use by everyone.
UN/CEFACT XML and all underlying standards (i.e. Core Component Methodology, Library, Message
Assembly, XML Naming and Design Rules) are maintained on a regular basis by UN/CEFACT, within the
United Nations framework of the Economic and Social Council, the United Nations Economic
Commission for Europe (UNECE). The maintenance process is documented, applied and governed. All
relevant procedural documents are available. Open participation for all interested stakeholders is
ensured through the national delegations, which are usually connected to the national standards bodies.
Also recognized organisations are able to participate in the development and maintenance process.
UN/CEFACT standards are actively used worldwide in various sectors like Agriculture, Transport and
Logistics, B2G EProcurement and cross-sector applicationsin different regions (APAC, US, Europe,
LatAm).
Apart from Invoice (CII) implementations, UN/CEFACT standards are implemented within the US
Department of Defence. Within the global GS1 Community UN/CEFACT XML is used (apart from
EANCOM and GS1 XML) in several countries worldwide. In other industries and domains CII and
UN/CEFACT syntax has been adopted as well, e.g. Japan, Taiwan (Single Window for reference WCO
DATA MODEL and UN/CEFACT XML and UNTDED) or Korea (cross industry tax e-invoice is obligation
of law).
CII, as part of cross-sector supply chain processes is implemented in various European countries, e.g.
— French Public eInvocing Platform (CHORUS)

CEN/TS 16931-3-3:2020 (E)
— German B2B and B2C core invoice standard (ZUGFeRD)
UN/CEFACT provides the relevant standards and guidelines on their website.
Support to the implementers and users is provided through other standardization bodies (e.g. CEN,
GS1), user communities, experts who are members of a national delegation at UN/CEFACT, etc. which
building their recommendations/guidelines upon published UN/CEFACT standards.
UN/CEFACT offers the CCBDA CCL message assembly methodology as guideline on how to modify the
underlying data model to enable subsetting. Applying the respective naming and design rules the syntax
becomes restricted or extended.
CCBDA supports message assembly and message contextual customisation based on the Reference ABIE
Library of the CCL. It is important to explain that extension is supported within the bounds of those
reference ABIEs and, of course, submissions to extend any ABIE can be submitted to Library
Maintenance for future inclusion. The aim is a controlled mechanism on extensions in order to facilitate
interoperability.
Using this standardized approach the EN requirement to take into account the UN/CEFACT XML Cross
3 4
Industry Invoice v.2.0 and v.3.0 is reached .
In order to take the most current version of the Cross Industry Invoice into account to be prepared best
possible to support an easy, sustainable and effective implementation of the EN using the Cross
Industry Invoice the Syntax mapping is done to Cross Industry Invoice version 100 (release D16B
SCRDM). This version contains two sets of schemas. One with coupled code list modules that allow a
one-step validation for the UN/CEFACT Standard; the second with decoupled code list modules. For
syntax binding of EN 16931-1 electronic invoices, the second set of schemas (decoupled) shall be used
to get a fully backwards compatible and stable implementation that enables a system to take future
code list updates into account.
4.2 Data types
Data Types and relevant Codelists for the Cross Industry Invoice can be found in the Requirement
5
Specification Mapping (RSM) document at the UNECE website . The following additional rules are
applied:
— For the udt:DateTimeType only the DateTimeString choice shall be used. For the corresponding
attribute @format the codelist UN/CEFACT 2379 is applied.
— The mapping of the SDM only code “102” (YYYYMMDD) shall be used. In a scenario with applied
extensions the two additional formats 610 (YYYYMM) and 616 (YYYYWW) can be used as well.
4.3 Codes and identifiers
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 listscan be used without any
additional mapping. For the following codes lists special rules are applied:
— ISO 4217 (Currencies): The alpha-3-representation shall be used. The currency shall only be given
on document level in /rsm:CrossIndustryInvoice/rsm:SupplyChainTradeTransaction/

TaxCurrencyCode is to be used the currency code shall be given at the appropriate element.
— BT-8 (Value added tax point date code). While the model defines a restriction of UNTDID 2005, CII
supports in the mapped to element a restriction of UNTDID 2475 as follows.

4.4 Mapping the Invoice model
In the following table the semantic data model of the EN 16931-1 is mapped to the corresponding
XPaths of the Cross Industry Invoice 100 (D16B) message structure. The cardinality column for the
syntax represents the cardinality as it is defined by UN/CEFACT to illustrate differences between the
semantic data model and the respective syntax. The cardinality of the data model is taken into account
by the corresponding validation artefacts.
