Extension Registry

This repository contains the two authoritative tables (CSV files) that list the registered OCDS extensions:

How to register an extension

Adding a new extension

Create an issue with a link to your extension. The registry's maintainers will evaluate its quality and relevance and provide feedback in the created issue or in the extension's repository. When appropriate, the maintainers will update the registry and close the issue.

Adding a new version of an extension

Create an issue or pull request about updating extension_versions.csv. See below on how to edit this file.

How to edit the CSV files

extensions.csv

This file has one extension per row. The row order has no effect, but alphabetical order is maintained for easier scanning and change tracking.

The CSV columns are:

  • Id (required): A unique identifier for the extension, composed of underscores and lowercase and uppercase ASCII letters. If the extension follows the extension naming guidance, this Id can be the extension repository's name, without the ocds_ prefix and _extension suffix.
  • Category: The standard documentation lists, in specific locations, extensions that target a specific part of the schema. Extensions may set a category to appear in one of these lists.
  • Core: The standard documentation defines core extensions, and the standard's governance process determines whether an extension is core.

extension_versions.csv

This file has one version (or release) of an extension per row. The row order has no effect, but alphabetical order is maintained for easier scanning and change tracking.

A version of an extension can be either 'live' or 'frozen'. A live version is continously updated at the same URL; for example, an author publishes an extension on GitHub, and continously updates the default branch. A frozen version is published once at a given URL and never updated; for example, an author tags a commit and releases that version of the extension. An extension can have both live and frozen versions. An extension ought to have only one live version.

The CSV columns are:

  • Id (required): An Id from extensions.csv.
  • Date:
    • If the extension is frozen, this is the date of the release (e.g. as shown on the extension's releases page on GitHub), or the date on which the row was inserted.
    • If the extension is live, this is blank.
  • Version (required):
    • If the extension is frozen, this is the tag of the release (e.g. as shown on the extension's releases page on GitHub), or a version number chosen by the extension's author.
    • If the extension is live, this is the branch name at which the version is continuously updated, or a version name chosen by the extension's author.
  • Base URL (required): The URL to which extension.json can be appended to retrieve the metadata for this version of the extension.
  • Download URL: The URL to retrieve a ZIP archive of this version of the extension.

Maintenance

Install dependencies:

pip install -r requirements.txt

To add a new extension to extensions.csv and extension_versions.csv, run, for example:

./manage.py add https://github.com/org/repo

To check for new versions of registered extensions, run:

./manage.py refresh

The standard documentation renders lists of community extensions using an extensions.json file, that aggregates information from the registry and each extension. This file is published at build/extensions.json. To regenerate the file:

./manage.py build

This repository has tests to validate extensions.csv and extension_versions.csv and to check the integrity of extensions.json.
