PD CEN/TR 17015-101:2018

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.
