Description
This WordPress plugin adds Dublin Core Metadata Element Set v1.1 meta tags to the head of your site. Dublin Core elements are a subset of RDF and help with the discoverability of your site.
Supported elements
The complete Dublin Core Metadata Element Set v1.1 is supported.
Settings
On the settings page (Settings > DC Meta Tags) you can configure the meta tags:
- Select which elements should be included with a default value only, and which should allow editing in the post’s meta box: the field mode
- Select the type of default value you want, and enter a default text value, for any fields
- Select on which post types the meta tags should appear
- Indicate if you want HTML4, XHTML, or HTML5 syntax
Field modes
Meta box on posts
On the add/edit post screens a meta box is available to override the default meta values.
All the elements in the meta box are multivalue, e.g. you may indicate more than one language, more than one description etc.
Only for documents
Since the Dublin Core Metadata Element Set v1.1 describes documents, it is only added to attachments, pages, posts and custom post types. No metadata is added to non-editable pages like the home page, archives, etc.
Installation
- Upload
dc-meta-tagsfolder to the/wp-content/plugins/directory - Activate the plugin through the ‘Plugins’ menu in WordPress

Frequently Asked Questions
How is the metadata generated?
The metadata is automatically generated based on the post title, author, excerpt, categories, tags, etc.
Can I override the generated metadata for specific posts?
Yes, a meta box is available on the add/edit post screens.
Where is the meta box? I don't see it.
Go to ‘Screen options’ and make sure ‘Dublin Core Metadata’ is checked.
I don't like the unnessary closing slash in the HTML5 output. Can I remove it?
Add define ('DCM_HTML5_CLOSING_SLASH', false); to your wp-config.php and you’re good to go.
What happens to data that’s no longer needed?
It’s deleted. When a field goes from ‘Editable’ to ‘Default only’, the values entered on it are no longer needed, and are therefore removed. Be careful!
Likewise, if the plugin is removed, all the metadata is removed from the database.
