Extensions¶
OCDS provides a common core of sections and building blocks for describing contracting processes.
De nombreux producteurs de données ont des données supplémentaires qu'ils pourraient publier. Au lieu d'ignorer ces données et de les laisser non publiées, OCDS encourage les producteurs de données à collaborer pour la création d'extensions au standard.
Some extensions are maintained by the Open Contracting Partnership (OCP). Those that are likely to be relevant to a large number of publishers and users follow the governance process. The standard development team decides which extensions follow the governance process.
Other extensions are maintained by third parties, like OCDS publishers, and do not follow the governance process. These extensions might provide features which are needed by only a small number of publishers or users, or they might be used to document a specific publisher's additional fields or codelist values.
All OCP extensions and many third-party extensions are documented in the Extension Explorer. The standard development team decides which extensions are registered in the Extension Registry, which controls which extensions appear in the Extension Explorer.
You are encouraged to consider using the extensions tagged as Recommended in the Extension Explorer.
Utiliser des extensions existantes¶
Les extensions sont appliquées en ajoutant leurs URL dans l'array extensions dans le package de la version ou le package d'enregistrement. Vous pouvez trouver les extensions, lire leur documentation et trouver l'URL à ajouter à l'aide de Extension Explorer.
This version of OCDS uses these specific versions of the following extensions:
Développement de nouvelles extensions¶
Si vous avez des champs qui n'ont pas de correspondance avec le schéma OCDS ou sur une extension existante, vous devez les inclure dans vos données OCDS et créer une nouvelle extension pour documenter leur structure et leur signification.
Modèle d'extension¶
Vous trouverez le modèle d'extension sur GitHub. Il contient des indications sur la création d'une extension.
Profiles¶
Groups of extensions can be combined into profiles. OCDS provides a common core for describing contracting processes, which profiles expand to suit the disclosure requirements and user needs of a particular sector or legal framework.
OCDS for Public-Private Partnerships¶
OCDS for Public-Private Partnerships (PPPs) describes how to use OCDS to publish information about PPPs. The profile extends OCDS to offer a data format that follows the World Bank Group’s Framework for Disclosure in Public-Private Partnership Projects.
OCDS for the European Union¶
OCDS for the European Union describes how to express, in OCDS, the information in Tenders Electronic Daily (TED) notices as obliged by law within the EU.
OCDS for the Agreement on Government Procurement¶
OCDS for the Agreement on Government Procurement (GPA) describes how to use OCDS to publish information as obliged by the World Trade Organization’s Agreement on Government Procurement.
