Factchecker's Schema.org ClaimReview manager for WordPress

NOTE: developer edition

This is a new plugin and we are testing it in the wild before releasing it as a plugin in the WordPress plugin repository.

Please install on your site, or in staging, and feel free to contribute with Pull Requests and become a contributor.

About this plugin

This is a WordPress plugin that allows publishers to add the new ClaimReview - schema.org schema for publishing factchecking reports to their posts.

You can read more about the labeling of fact checking articles in Labeling fact-check articles in Google News.

Installing on a website

This is currently a work in development - and while it should be fine to use with your site - it has not yet been released as a WordPress plugin.

Plugin and Settings

  1. copy the plugins/wp-factchecker-claim-review folder to your site's plugin folder
  2. Activate the plugin via the WordPress plugin settings
  3. Under Settings > Factchecker ClaimReview Settings set your organisation detail, and choose the post types that will have ClaimReview schema

Adding ClaimReview Schema to posts

Claims are separate from posts and can be reused - and are defined as a Custom Post Type.

For the post types enabled above, a new metabox will appear in the right column when editing a post.

You can search for existing ClaimReviews, or create new ones.

Save/Publish your post, and your new ClaimReview Schema data will be added to the HTML when the post renders.

Contributing to the development of this plugin

This is a simple start - there is much to be done. Please contribute to make this a well rounded and useful plugin.

To make development easier I have added a docker-compose configuration, which will allow you to spin up a local version of a wordpress site in Docker Containers and focus on developing the functionality of this plugin.

This is not a requirement, but I find it a useful way to work. Read more about setting up docker in your development environment

Development approach

I think it's important to have this as a zero-dependency plugin, so it can have as low a barrier to adoption as possible. I have therefore not used any 3rd-party plugins for things like custom fields or JavaScript - only what is available with a standard WordPress plugin.
