This profile is intended to ease the synchronization of a catalogue between the selling and the buying side, in particular to provide light-weighted transaction to update parts (existing items and item prices) of the catalogue. In this profile the selling side can be any Economic Operator and the buying side any Contracting Authority. So intended scope for this profile includes are B2G relationships.
The transactions, specified in this profile are intended to be exchanged between the procurement systems of contracting authorities and systems for catalogue management of economic operators. This means that it is expected that the parties have connected their systems to the internet, and that they have middleware in place to enable them to send and receive the transactions in a secure way, using an agreed syntax.
In this profile, only existing items in the catalogue at the customer's side can be updated. For adding new items or removing items, the profile BII01 Catalogue Only must be used. To suspend completely the usage of a catalogue the profile BII16 Catalogue Deletion must be used.
