Most economically advantageous tenders (MEAT)

Besides simple price-only tenders it is possible to announce the tender where other factors are valuable. Such tenders define features that procuring entity is interested in and how much different options influence the decision about the winner. Features can describe properties of tenderer, lot or item(s) being procured. Each option offered has numerical value that defines level of its importance compared to price. Bidders are doing self evaluation and provide the Parameters of their proposal (the actual value of each feature) along with financial part of a bid.

For more information read Non-price criteria.

The Feature is a data structure, part of the Tender. Tender can have multiple features associated. Feature can be associated with tenderer, lot or individual Item being procured. Features are identified with code, which are unique within the tender.

Announcing MEAT

Features can be set in Tender pretty the same way as Items are - with POST request.

POST /tenders HTTP/1.1

{"data": {
  ...
  "features": [...],
  ...
}
HTTP/1.1 201 Created
Location: /tenders/64e93250be76435397e8c992ed4214d1

Changing Features

In the case that Features should be changed one can send PATCH that replaces Tender.features with new set:

PATCH /tenders HTTP/1.1

{"data": {
  "features": [...]
}
HTTP/1.1 200 OK

Removing Features

In case no Features are needed, they can be removed altogether with following request:

PATCH /tenders HTTP/1.1

{"data": {
  "features": []
}
HTTP/1.1 200 OK

Bidding in MEAT

The same applies to Bid - Parameters of a Bid can be set initially with POST request and modified later with PATCH requests (see more at Bidder Operations).

POST /tenders/64e93250be76435397e8c992ed4214d1/bids HTTP/1.1

{"data": {
  ...
  "parameters": [...],
  ...
