28、er a six-year period” 1) . Based on this recognition “The Commission 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 5 on electronic invoicing in public procurement aims at facilitating the use of electroni

29、c invoices by economic operators when supplying goods, works and services to the public administration. In particular, it sets out the legal framework for the establishment of a European Standard (EN 16931-1) for the semantic data model of the core elements of an electronic invoice. The semantic dat

30、a 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. In line with Directive 201

31、4/55/EU 5, all contracting authorities and contracting entities in the EU will be obliged to receive and process an e-invoice as long as it contains all of the core elements of an invoice defined in EN 16931-1 and provided that it is represented in any of the syntaxes identified in the related Techn

32、ical Specification CEN/TS 16931-2 “List of syntaxes that comply with EN 16931-1”. This CEN Technical Specification CEN/TS 16931-3-1:2017 defines the method by which the core elements of the invoice should be mapped to a syntax. Subsequent CEN Technical Specifications apply this method and map the co

33、re invoice model to syntaxes such as UBL (CEN/TS 16931-3-2), UN/CEFACT XML (CEN/TS 16931-3-3) and the ISO 9735 series (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 remo

34、ve 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) http:/eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=COM:2010:0712:FIN:en:PDF.

35、17 (E) 5 1 Scope This Technical Specification (TS) specifies the methodology of the mapping between the semantic model of an electronic invoice, included in EN 16931-1 and a syntax. For each element in the semantic model (including sub-elements or supplementary components such as Identification sche

36、me identifiers) it should be 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. 2 Normative references The following documents, in whole or in part, are normatively referenced in thi

45、 core elements of an electronic invoice. The purpose of the core semantic invoice model is to facilitate computer applications generate electronic invoices and then for other applications receive and process those invoices automatically. These electronic invoices are electronically transmitted and r

46、eceived, without the need for prior bilateral agreement on the content or elements of the invoice. However, in order to exchange electronic invoices, the model elements need to be represented in a “syntax”. A syntax specification allows the computer systems to identify the content (element values) a

47、s part of a data stream. Syntax specifications imply a semantic model. The syntax specification defines how elements are organized (structured and serialized) in a predefined way in a data stream. Each element can be identified by means of its position or sequence, or by means of tags or labels. A s

48、yntax specification also defines the semantics of the elements, by naming and/or defining them. As such each syntax, by its own rules and methods, defines a standardized semantic model of an electronic invoice. A syntax specification also defines the grouping, hierarchy, data types, formats and card

49、inality of the elements. In order to represent a standardized semantic model, such as the EN 16931-1 model, in a syntax, it is defined as a subset of a given syntax specification. The elements of the syntax specification may be more precisely defined, their cardinality may be restricted and their data types may be narrowed. A syntax binding specification (this document), or mapping, describes how a semantic model, such as the model defined in EN 16931-1 is mapped to a selection of syntax spec
