Restore buyer and suppliers fields

[jpmckinney]

These are renamed to publicAuthority and preferredBidders. This makes OCDS for PPPs data unnecessarily incompatible with OCDS data. The original terms are inappropriate, but this needs to be fixed in an OCDS 2.0, not in a profile. For OCDS 1.2, the fix is to broaden the definitions of buyer and suppliers, while retaining the terms.

Agreed, sounds good.

[jpmckinney]

@duncandewhurst Since OCDS for PPPs is relevant to a few active implementers, and since you might be making changes to close #238, could you take on this issue, #237 and ideally #217 ?

[duncandewhurst]

Sure, should I prioritise those above 1.2 issues?

[jpmckinney]

Yes, looks like Matt, Kadie and Charlie have taken on enough 1.2 issues for now.

@jpmckinney a couple of questions on your preferred approach:

• Should we remove publicAuthority and preferredBidders completely, or should we deprecate them?

• Should we also remove/restore the associated codes in partyRole.csv?

Should we remove publicAuthority and preferredBidders completely, or should we deprecate them?

Since the profile isn't 1.0 but is beta, I think better to remove.

Should we also remove/restore the associated codes in partyRole.csv?

Yes, good catch.
