Is your WordPress theme or website built with inline Schema.org Microdata? As search engines increasingly prefer the JSON-LD format for structured data, updating your site can be a significant challenge. Manually removing old Microdata and creating new JSON-LD scripts for every page is tedious and prone to errors.
The Microdata to JSON-LD Converter solves this exact problem. This plugin seamlessly automates the entire conversion process:
<ol>
<li>Scans Your Pages: It fetches the full HTML of your published posts and pages, ensuring it captures all Microdata, whether it’s in your post content or your theme files (like <code>header.php</code>).</li>
<li>Converts to JSON-LD: It intelligently parses the <code>itemscope</code>, <code>itemtype</code>, and <code>itemprop</code> attributes and converts them into a well-structured JSON-LD script.</li>
<li>Removes Inline Microdata: Optionally, it can clean up your public-facing HTML by removing the now-redundant Microdata attributes, leaving only the clean JSON-LD script in the <code><head></code>.</li>
<li>Keeps It Fresh: With the “Keep up to date” option, the plugin can automatically regenerate the JSON-LD every time you update a post, ensuring your structured data always reflects your latest content.</li>
</ol>
Key Features:
<ul>
<li>Full Page Parsing: Accurately reads Microdata from the entire webpage, not just post content.</li>
<li>Automatic Generation: Automatically creates the initial JSON-LD when you open a published post for the first time.</li>
<li>Manual Control: View and edit the generated JSON-LD directly in a meta box on each post’s edit screen.</li>
<li>Built-in Validator: Get instant feedback on your schema with a built-in validator that checks for common required and recommended properties.</li>
<li>Bulk Rebuild Tool: Process your entire site at once with a batch-processing tool that works through all your posts and pages.</li>
<li>“Set It and Forget It” Mode: Enable the “Keep JSON-LD up to date” option to ensure your structured data remains current.</li>
<li>Clean & Modern UI: A simple, intuitive settings page with toggle switches and tabs makes configuration a breeze.</li>
</ul>
This plugin offers a seamless migration path for modernizing your site’s SEO and structured data implementation, eliminating the need to edit your content, plugins, and theme files.

Also it will provide the site admin the option to add a link to those associated Wikidata items to the head metadata section, or to the tag/category archive title.
User will also have the option to frame tag and categories archive pages links into a Schema.org 
microformat.

Wikidata References for WordPress

Really liked this plugin. Useful. Doesn't add unnecessary taxonomies. Would be interested in seeing what other features it could add. Authors with Wikipedia pages or Wikidata entries could be linked as well from their profiles. 

One of the few plugins that seems to get the core idea really well.

Very excellent
