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-tags folder to the /wp-content/plugins/ directory
Activate the plugin through the ‘Plugins’ menu in WordPress
Go to Settings > DC Meta Tags to configure it if necessary

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.
