CEN/TC 440 - Project Committee - Electronic Public Procurement

The purpose of this deliverable is to specify and describe choreographies for exchanging an electronic product catalogue (“catalogues”) as part of the business processes in the pre-award and post-award area, so that catalogues can serve as a basis for placing orders as well as evaluating tenders. The key aspects covered by this choreography specification are:
-   processes for submitting catalogues from the selling to the buying side;
-   processes for submitting catalogue-related data as part of a tendering process;
-   processes integrating sell-side procurement systems.
This document does not apply to the transactions used in the specified choreographies. These transactions are specified in EN 17015 2. The relationship between the choreographies and the transaction is described in Clause 8.
The identifier of this choreographies document is EN 17015 1:2024.
How to claim compliance to this choreography is specified in 6.2.3.

This choreographies document specify ordering between Buyer and Seller where the Buyer wants to reach an agreement with the Seller about an order. It specifies a series of activities that govern communication between the parties and refers to the specifications where information and rules that apply are specified.
The various possible behaviours of the Seller and Buyer subsequent to the first order communication are conveyed by variants of this choreography that are specified in 5.2.
Previous activities (e.g. cataloguing) and subsequent activities (e.g. invoicing) are outside the scope of this document. If performed electronically, their implementation is covered by other choreographies.
The identifier of this choreographies document is EN 17016-1:2024.
How to claim compliance to this choreography is specified in 5.2.3.

This document provides an overview of e-ordering standards in the set Business Interoperability Inter-
faces (BII) for public procurement. E-ordering covers the e-sourcing and e-ordering business areas of the
e-procurement chain,  starting  from  the awarding of  the  contract  or  the  receiving  of  a  quotation  to the receipt of a despatch advise or a receiving advice for the goods or services that have been ordered.

This document  provides  an overview  of  standards in the set  Business  Interoperability Interfaces (BII) for public  procurement. It covers the first part of the e- procurement chain. BII focus  on exchange of information between  business  partners. This brings in  scope all  electronic  communication between a contracting authority and an economic operator. Back-office information processing is out of scope.
To ensure interoperability each electronic communication will be described as follows:
- A choreography describes the sequence of transactions;
- A transaction describes all information elements exchanged between business partners;
- A syntax implementation guideline (SIG) provides the syntax bindings needed to implement the transaction
- A procurement procedure guideline identifies the position of the transactions in a procedure.

This document provides an overview of eTendering standards in the set Business Interoperability Interfaces (BII) for public procurement. BII eTendering covers the tendering part of the e-procurement chain, starting from subscribing interest in a business opportunity till concluding the contract.
BII focus on exchange of information between business partners. This brings in scope all electronic communication between a contracting authority and an economic operator. Back-office information processing, like the evaluation of tenders, is out of scope.
To ensure interoperability each electronic communication will be described as follows:
- A procurement procedure guideline identifies the position of the transactions  in a procedure;
- A choreography describes the sequence of transactions;
- A transaction describes all  information elements exchanged between business partners;
- A syntax implementation guideline (SIG) provides the syntax bindings needed to implement the transaction.

The  CEN/TC  440/WG5  has  developed  a  set  of  deliverables  to  support  interoperability  in  the  pre- and  post-award areas of public procurement. In particular, the deliverables cover the exchange of electronic product catalogues and related  documents  between  contracting  bodies  and  economic  operators  respectively  buyers  and  sellers.  An  electronic product catalogue contains specifications of products (goods and services) with their pricing. A catalogue is used to serve as a basis for ordering and all other following post-award processes. To ensure interoperability each electronic communication will be described as follows:
• A choreography describes the sequence of transactions;
• A transaction describes all information elements exchanged between business partners;
• A syntax implementation guideline (SIG) provides the syntax bindings needed to implement the transaction.

This document describes the transaction information requirements of the transactions used in the collaborations described in EN 17016-1:2024, Electronic Public Procurement - Ordering - Part 1: Choreographies. For each transaction are specified the transaction business requirements, the transaction information data model containing definitions of terms, usage descriptions and cardinality of the information elements and the transaction business rules.
This document describes the following transactions:
1)   Order;
2)   Order Change;
3)   Order Cancellation;
4)   Order Response Simple
5)   Order Confirmation;
6)   Order Rejection;
7)   Order Response;
8)   Order Change Confirmation;
9)   Order Change Rejection;
10)   Order Cancellation Confirmation;
11)   Order Cancellation Rejection;
12)   Order Agreement.
The identifier of this transactions document is EN 17016-2:20XX.
How to claim compliance to a transaction is specified in Clause 6.
How to claim conformance to a transaction is also specified in Clause 6.

This document describes the transaction information requirements of the transactions used in the basic
collaborations described in EN 17015-1 Electronic Public Procurement – Catalogue – Choreographies.
For each transaction there is an overview, the transaction business requirements and the transaction information requirements model containing definitions of terms, usage descriptions and cardinality of the information elements.
The document describes the following transactions:
1) Catalogue;
2) Catalogue Response
3) Pre-award Catalogue Request
4) Pre-award Catalogue
5) Shopping Cart
How to claim compliance to a transaction is described in paragraph 6.
How to claim conformance to a transaction is described in paragraph 6.

This choreography describes the exchange of information in the Fulfilment phase between seller and buyer where the seller wants to announce delivery of the ordered goods or services. The purpose of the fulfilment it is to monitor the executions of the contract. This process is the process between the ordering process and the billing process. The billing process can start when fulfilment has been initiated.
The business value for this is
• To prepare the buyers organisation for the physical delivery.
• To enabling an automatic check of delivery for the buying organisation before paying the received invoice.
• To match the ordered products with the physical deliveries, such as serial numbers, lot identifiers and other information that may not be present at the time the goods were ordered.
• The assist in getting an accurate calculation of the environmental footprint of the goods by including the emission during the transport.
• To feed data into the logistic process, so no retyping is needed during the transport of the goods.
Transactions used in the specified choreographies are out of scope. These transactions are specified in the related transaction specification on “Fulfilment Transactions”.

This document describes:
-   the rationale for building customisation supporting business cases that are specific to their business environment while maintaining organisational and semantic interoperability with the TC 440 specifications;
-   the difference between Usage specification and Extension specification;
-   a methodology on how to define customisations on:
-   BII Transaction specification,
-   Business rules,
-   Code lists;
-   how to claim compliance or conformance to a customisation of a TC 440 specification;
-   the connection to the eProcurement Ontology project.
This specification does not describe the detailed process of building an extension.
