OCDS for Public Private Partnerships

The Open Contracting Data Standard for Public Private Partnerships profile provides an extended Open Contracting Data Standard schema, offering a structured data model for presenting information on Public Private Partnership Projects.

It is based on the World Bank Framework for Disclosure in Public Private Partnership Projects and was developed between May 2016 and May 2017 through a partnership between the World Bank Open Contracting team, PPP team, Open Contracting Partnership, and Open Data Services Co-operative.

Full documentation of the profile is available at http://standard.open-contracting.org/profiles/ppp/

The consolidated OCDS for PPPs extension can be declared in OCDS package metadata using:

{
    "extensions":["http://standard.open-contracting.org/profiles/ppp/extension/1__0__0__beta/extension.json"],
    "releases":[]
}

About PPP extensions

OCDS for PPPs is constructed from a number of different modular extensions to OCDS, most of which can be used independently from the profile.

This repository contains one additional extensions that forms part of the OCDS for PPPs profile. This extension introduces a number of fields and building blocks that are specific to PPP disclosure against the World Bank Framework, as well as a set of modifications that should only apply in an OCDS Profile (e.g. removing standard fields that are not required in the profile).

Evaluation Indicators

The PPP disclosure framework calls for a number of different indicators to be reported relating to governments evaluation of a PPP project.

The award/evaluationIndicators section includes properties to express the value and supporting free-text details for each indicator:

  • discountRate
  • riskPremium
  • netPresentValue

Finance Summary

The PPP disclosure framework calls for a number of different indicators relating to the financial model of a PPP project. Whilst some of these may be reported as metrics on an ongoing basis, some are simple single values.

The contract/financeSummary section includes properties to express the value and supporting free-text details for each indicator:

  • debtEquityRatio
  • shareCapital
  • subsidyRatio
  • projectIRR

Removals

A standard OCDS extension should not remove content from the OCDS schema. However, to allow us to generate a profile schema and reference pages that contain only fields that should be considered when publishing OCDS for PPPs data, the release-schema.json for this extension contains a number of null fields, which remove schema elements not used by OCDS for PPPs.

This includes elements deprecated in OCDS 1.0, or procurement specific elements that don't apply in a PPP context.
