This European Standard establishes a semantic data model of the core elements of an electronic invoice. The semantic model includes only the essential information elements that an electronic invoice needs to ensure legal (including fiscal) compliance and to enable interoperability for cross-border, cross sector and for domestic trade. The semantic model may be used by organizations in the private and the public sector for public procurement invoicing. It may also be used for invoicing between private sector enterprises. It has not been specifically designed for invoicing consumers.
This European Standard complies at least with the following criteria:
-   it is technologically neutral;
-   it is compatible with relevant international standards on electronic invoicing;
-   the application of this standard should comply with the requirements for the protection of personal data of Directive 95/46/EC, having due regard to the principles of privacy and data protection by-design, data minimization, purpose limitation, necessity and proportionality;
-   it is consistent with the relevant provisions of Directive 2006/112/EC [2];
-   it allows for the establishment of practical, user-friendly, flexible and cost-efficient electronic invoicing systems;
-   it takes into account the special needs of small and medium-sized enterprises as well as of sub-central contracting authorities and contracting entities;
-   it is suitable for use in commercial transactions between enterprises.

This document provides requirements and recommendations for the design and use of pictograms, photos, and icons in augmentative and alternative communication (AAC) in the information and communication technology (ICT) domain. This document recognizes that AAC can be delivered on various sized devices including computer displays, tablets, and smart phones. It applies to pictograms, photos, and icons that can be used on a range of devices. It is not specific to particular devices or the particular software used. This document focuses on the needs of those users who cannot use a natural language in written or spoken form to communicate with a peer group or the community as a whole. In facilitating communication with those other people, it also serves them.

This document provides an introduction to and basic guidance on augmentative and alternative communication (AAC) in the information and communication technology (ICT) domain. It also provides common definitions and a framework for the development of further, more detailed guidance relating to aspects of these AACs. This document recognizes that AAC can be delivered on various ICT devices and the importance of consistency for users across devices. It applies to AAC software and not the devices on which the software is used. This document recognizes that AAC provides many users with a unique form of communication that is not necessarily based on any specific natural language.

The European Commission will in its project "VAT in the digital age" (ViDA) mandate that VAT reporting on intra-EU transactions is performed in near real-time and based on EN 16931-1. This Technical Report defines the impact of this legislation on the various deliverables of CEN/TC 434, with a focus on the subset to be sent to tax authorities and how EN 16931-1 needs to be changed. The ViDA package applies to all EU member states and specific territories where the VAT legislation applies (e.g. Northern Ireland in respect to goods).
This document does not define the content of the common electronic message based on the electronic invoice to be sent to the authorities. The definition of that common electronic message (DRR message) is a task of the European Commission, possibly with help of CEN. As the DRR message is not an invoice, but a VAT report, it is not to be regarded as a Core Invoice Usage Specification (CIUS). The DRR message therefore needs not to obey the rules for developing a CIUS. For example, not all mandatory elements in the invoice need to be part of the DRR message.

This document defines the standardized mapping of the specific requirements of an insurance premium invoice to the generic electronic invoice described in EN 16931-1. This mapping meets the requirements of an electronic premium invoice to ensure legal (including fiscal) compliance as well as business and technical demands of the insurance industry.
Premium invoices can be issued by different organizations of the insurance industry to commercial clients or consumers. This document includes premium invoices issued by insurance companies as well as insurance intermediaries.
This document does not deal with data protection matters in premium invoices.
NOTE   General Data Protection Regulation, EU Regulation 2016/679 can include requirements on personal data.
Premium invoices are regularly not subject to VAT but to special taxes. In particular, the requirements resulting from insurance tax regulations are considered. Requirements for other taxes are also incorporated.
The rules defined in EN 16931-1 do not support invoices with amounts not subject to VAT together with additional amounts which are subject to VAT. Therefore, this document also does not support premium invoices which invoice other goods and services which are subject to VAT invoiced together with premium amounts.
Out of the scope of this document are accounting transactions between insurance companies and insurance intermediaries which may contain premium invoice data, but regularly consist of other data (e.g. commissions) which are not part of a regular invoice.

This European Standard establishes a semantic data model of the core elements of an electronic invoice. The semantic model includes only the essential information elements that an electronic invoice needs to ensure legal (including fiscal) compliance and to enable interoperability for cross-border, cross sector and for domestic trade. The semantic model may be used by organizations in the private and the public sector for public procurement invoicing. It may also be used for invoicing between private sector enterprises. It has not been specifically designed for invoicing consumers.
This European Standard complies at least with the following criteria:
-   it is technologically neutral;
-   it is compatible with relevant international standards on electronic invoicing;
-   the application of this standard should comply with the requirements for the protection of personal data of Directive 95/46/EC, having due regard to the principles of privacy and data protection by-design, data minimization, purpose limitation, necessity and proportionality;
-   it is consistent with the relevant provisions of Directive 2006/112/EC [2];
-   it allows for the establishment of practical, user-friendly, flexible and cost-efficient electronic invoicing systems;
-   it takes into account the special needs of small and medium-sized enterprises as well as of sub-central contracting authorities and contracting entities;
-   it is suitable for use in commercial transactions between enterprises.

Furthermore, this document provides guidance for the creation and implementation of a CIUS.
The following points are the focus:
-   steps that need to be taken in consideration to avoid unnecessary proliferation and fragmentation in the use of CIUSs;
-   guidance on the creation and implementation of CIUSs, with a quality control objective.
It should be noted that it is planned to apply the same principles and processes to extensions that are documented in a separate document.
