Abstract

This European Norm is based upon the directives 2014/24/EU on public procurement and 2014/25/EU on procurement by entities operating in the water, energy, transport and postal services sectors and 2014/23/EU on the award of concession contracts and 2009/81/EC on the coordination of procedures for the award of contracts in the fields of defence and security. Supplementary regulations such as Implementing Regulation (EU) 2019/1780 establishing standard forms for the publication of notices [eForms] and Implementing Regulation (EU) 2016/7 establishing the standard form for the European Single Procurement Document [ESPD] have been considered for the collection of the underlying legal requirements.

The document describes the transaction information requirements of the transactions used in pre-award processes between Contracting Entities (Buyer) and Economic Operators (Seller) where the Contracting Entity wants to contract an Economic Operator for the purchase of products, services and works. The various possible behaviours of the Seller and Buyer subsequent to the communication are conveyed by variants of the choreography described in EN 17014-1:2025.

For each transaction, the following elements are specified:

a) Transaction Business Requirements – A clear statement of the functional and procedural needs that the transaction must fulfill.

b) Transaction Information Data Model – A structured definition of all information elements involved in the transaction, including:

• Hierarchy of information data model

• Identification and definitions of business terms

• Cardinalities and semantic data types of information elements

• Usage descriptions

c) Transaction Business Rules – The logical constraints and conditions that govern the valid execution of the transaction.

d) Mapping of Data Elements to the eProcurement Ontology (ePO) – Each data element defined in the transaction information data model is aligned with the corresponding class, property, or relationship in the ePO, ensuring semantic interoperability and consistent representation across procurement systems.
