TED Mapping - Additional Addresses

[timgdavies]

In the EU TED standard there are a number of spaces for organisation details beyond the 'buyer', 'procuringEntity' and 'supplier' addresses captured in OCDS.

These appear to take two forms:

(1) Some are contact_contracting_body objects;
(2) Others are `contact_review`` objects

Addresses

The addresses include:

• Multiple possible addresses for CONTRACTING_BODY - in the ADDRESS_CONTRACTING_BODY_ADDITIONAL fields (1..49).
  • contact_contracting_body
  • These appear to be used when there is Joint Procurement
  • Question: Are there additional contracting bodies in cases without joint procurement?
• ADDRESS_PARTICIPATION
  • contact_contracting_body
  • Question: What is the exact semantics of this field?
• ADDRESS_FURTHER_INFO
  • contact_contracting_body
  • Address to request further info on the tender
• ADDRESS_REVIEW_BODY
  • Simpler address type contact_review
• ADDRESS_REVIEW_INFO
  • Simpler address type contact_review
• ADDRESS_MEDIATION_BODY
  • Simpler address type contact_review

Handling in OCDS

To handle these in OCDS we need to consider whether:

• (a) To create some sort of abstract 'additional organisations' array, which can contain a range of organisations each with a type;
• (b) To create explicit properties for each type of organisation;

My preference is towards (b).

In OCDS, address further info should probably also be serialised into the submissionMethodDetails field with some explanatory text.
