The “Dublin.rdf” file gives you an opportunity to define your site’s metadata using prescribed specifications managed by the Dublin Core Metadata Initiative. (http://dublincore.org/)

Why is it useful?

Search engine optimization (SEO) and clean, well-defined mark up have long been important and will continue to be so. This file is an easy addition to your site that provides the great benefit of allowing you to help shape how the search engines define the content.

How to create one
