Standards and codelists

Open Contracting Data Standard

Tenders, contracts and party roles follow the Open Contracting Data Standard (OCDS) where a comparable concept exists. The following codelists are used with the same values as the standard:

• procurement method: open, selective, limited, direct;
• main procurement category: goods, works, services;
• tender status: planning, planned, active, cancelled, unsuccessful, complete, withdrawn;
• contract status: pending, active, cancelled, terminated;
• party roles: buyer, procuring entity, supplier, tenderer, payer, payee, funder, guarantor.

This alignment means that an export from the platform maps onto OCDS fields without a translation table, and that OCDS publications can be ingested without losing their codes.

Deliberate departures

• Contract status adds completed for contracts whose performance period has ended without termination, because the distinction matters for performance analysis.
• Contract type adds concession and PPP so that long-term availability- and user-paid contracts can be separated from ordinary procurement.
• Party roles add operator and sponsor for the parties of long-term contracts.
• Contract events are a QinMetrics structure. OCDS records implementation through milestones, transactions and amendments; the event model unifies those with disputes, delays, penalties, reviews and terminations in one dated sequence.

Fiscal indicators

Fiscal data uses an indicator–observation model: an indicator is a defined measure, an observation is one value for one jurisdiction and one period. Indicator definitions state their relationship to the publisher's own categories, and to international government-finance frameworks where the publisher reports against one.

Codes and formats

• Countries: ISO 3166-1 alpha-2. Subdivisions: ISO 3166-2 where assigned, plus the national code scheme where one exists.
• Currencies: ISO 4217, three-letter codes, never symbols.
• Dates: ISO 8601, YYYY-MM-DD; timestamps with an explicit offset.
• Periods: YYYY, YYYY-Qn or YYYY-MM.
• Text: UTF-8 throughout; original scripts are preserved.
