Overview

EN 17015-1:2024 - Electronic Public Procurement – Catalogue – Part 1: Choreographies (CEN) defines the business choreographies for exchanging electronic product catalogues in public procurement. Approved by CEN in February 2024, the standard specifies how catalogues are shared and used across the pre-award and post-award lifecycle so that catalogues can act as a basis for placing orders and evaluating tenders.

Key scope points:

• Processes for submitting catalogues from sellers to buyers.
• Submitting catalogue-related data during tendering.
• Integration scenarios for sell-side procurement systems.
• Transactions used by these choreographies are specified in EN 17015-2; the relationship between choreographies and transactions is described in Clause 8.
• How to claim compliance is specified in Clause 6.2.3.

Key topics and requirements

• Business choreographies: Defined sequences of interactions (state machines, scenarios and business rules) that ensure consistent exchanges of catalogue data between parties.
• Process variants: The standard documents multiple variants (e.g., Catalogue With Response, Catalogue Without Response, Pre-award Catalogue variants, External Catalogue / Punch-out) including requirements, state diagrams and example scenarios.
• Interoperability focus: Designed to support system-to-system exchanges between procurement platforms, seller systems and eMarketplace components.
• Traceability to transactions: Clause 9 maps the choreography collaborations to concrete transactions (e.g., Catalogue sends, Catalogue Response, Pre-award Catalogue Request/Send, Shopping-cart).
• Conformance: Procedures for claiming compliance are provided (see Clause 6.2.3).
• Derivative use: The deliverable falls under CEN’s derivative-use pilot allowing specific implementation elements to be copied for software solutions where permitted.

Applications and practical value

This standard is practical for:

• Public authorities and procurement teams standardizing catalogue-based sourcing and tender evaluation.
• Software vendors and system integrators building eProcurement, eCatalogue, eOrdering and punch-out capabilities.
• Marketplaces and suppliers enabling catalogue submission, updates and punch-out shopping-cart workflows.
• National authorities adopting interoperable public procurement ecosystems across jurisdictions.

Practical benefits:

• Enables consistent catalogue-driven ordering and tender evaluation.
• Reduces integration complexity via defined choreography patterns.
• Supports automation from catalogue publication to order placement.

Related standards

• EN 17015-2 - Transactions (syntax and message definitions used by these choreographies).
• Other CEN/TC 440 series: EN 17011 (eProcurement Architecture), EN 17016 (eOrdering), EN 17017 (eFulfilment).

Keywords: electronic public procurement, eProcurement, eCatalogue, catalogue choreographies, EN 17015-1:2024, interoperability, catalogue exchange, pre-award, post-award.

Introduction
Derivative use pilot
This publication falls under a CEN-CENELEC pilot on derivative use (as approved by the CEN/CA

definitions and rules related to the use of information elements, and the name, definition and description
of processes and transactions, which are needed in software solutions, whether intended for sale in the
private market or for use in the public sector, and documents guiding the implementation and use in
specific countries and/or business sectors.
Under derivative use, any use of content, which has been copied, replicated or translated from a
CEN/TC 440 publication, should comply with the intended use of the publication. Derivative use cannot
be applied in use cases other than those the publication is intended to support. The intended use of this
publication is set out below.
Intended use of this publication
This document has been developed for any organization looking for guidance on the implementation and
use of electronic procurement deliverables as well as for organizations developing or implementing
software applications related to electronic procurement, such as software providers, business entities
and national authorities. These software applications should be in conformance with this publication.
Parts of the document to which derivative use apply
Each subclause, which falls under derivative use, will be clearly marked with a footnote. The degree to
which the specific content can be modified is specified in CEN/TS 17011-3 , Electronic Public

3.17
transaction
content of data exchanged or shared between the agents (3.1) in a collaboration (3.10)
Note 1 to entry: A transaction is the atomic unit that leads to a synchronized state in the information systems of
collaborating agents. It is the basic building block to specify the choreography between agents. When an agent
recognizes an event that changes the state of a business object within a business process, it uses a transaction to
synchronize with the collaborating agent. A transaction therefore changes the state of a business process. It carries
the intention of the initiating agent and is represented by a data structure that is required by a data model. The
exchange of a transaction may alter legal obligations between business partners.

6.1 General
In order to encompass the various maturity levels of organizations (see HLR-17015-1:2024-1), the
approach is to specify variants of business processes that use a set of activities around exchanging
information in different combinations. The main business entities dealt with within this choreography
are Catalogue and Catalogue Response.
The state machine diagram depicted in Figure 3 provides information on the common states for systems
to get in agreement.

6.2 Business processes variants
6.2.1 General
Two variants are identified as reported in the following table. They allow for supporting different levels
of interoperability maturity of the organisations willing to automate the exchange of information in the
business area at stake as specified by high-level requirement (HLR).
The variants combine in various ways the basic processes defined above through various collaborations

applied into the purchasing systems by both parties and used as base for
procurement, i.e. ordering and invoicing. Possibly by adding it to an
existing catalogue.

6.3.6 Business process variant A key examples [informative]
6.3.6.1 Example 1
An economic operator won a call for tender and now establishes the post-award processes with the
contracting authority. As part of this activity, he compiles a catalogue describing the products to be
offered by the economic operator. The catalogue is sent to the contracting authority.
The contracting authority checks the sent catalogue, to verify if all information requested by the
contracting authority and specified in the framework agreement between the contracting authority and
the economic operator is contained in the catalogue and that the catalogue complies with the (pre-award)
catalogue that was submitted by the economic operator in the tendering process. As the sent catalogue
fulfils all requirements, the catalogue will be forwarded to the ordering systems. Authorized employees
of the contracting authority are now able to place orders based on the information provided in the
catalogue.
The economic operator will be informed automatically by a catalogue response that the catalogue has
been accepted. The economic operator may receive orders from the contracting authority based on the
sent catalogue.
6.3.6.2 Example 2
An economic operator won a call for tender and now establishes the post-award processes with the
contracting authority. As part of this activity, he compiles a catalogue describing the products to be
offered by the economic operator. The catalogue is sent to the contracting authority.
The contracting authority checks the sent catalogue, to verify if all information requested by the
contracting authority and specified in the framework agreement between the contracting authority and
the economic operator is contained in the catalogue and that the catalogue complies with the (pre-award)
catalogue that was submitted by the economic operator in the tendering process. The catalogue does not
fulfil the requirements, because not all products in the catalogue are classified according to the agreed
classification systems as well as needed packaging information is missing. The catalogue will not be
forwarded to the ordering systems.
The economic operator will be informed automatically by the catalogue response that the catalogue is
rejected. No orders will be placed based on this sent catalogue.
