Curated Specifications

Reference Links

1. Overview

Centre for Digital Public Infrastructure (CDPI) curates open standards and specifications across various categories of DPIs for easy reference. This is an initiative to curate specifications that follow DPI principles to enable countries to create required Digital Public Infrastructure rails. This list includes open specifications that are published by non-profit global institutions or agreed upon based on a global governance, but also de-facto standards used by countries where the specifications have reached scale of over 10 Million+ transactions.

Note:

1. This is a draft and all stakeholders in DPI space can share their comments.

2. Reference implementations listed here are as per the claim of implementing org. CDPI has not verified the claims.

3. Countries are advised to independently verify at the time of the adoption.
