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.
