The following is an example of adding Dublin Core metadata to an XHTML file. Dublin Core data elements are data typically added to a book or article (title, author, subject etc.)

- Publisher Independence – each site can use its own standards
- Data Reuse – data is not duplicated. Separate XML and HTML sections are not required for the same content.
- Self Containment – The HTML and the RDF are separated
- Schema Modularity – The attributes are reusable
- Evolvability – additional fields can be added and XML transforms can extract the semantics of the data from an XHTML file
Five "principles of interoperable metadata" met by RDFa.[11]
Additionally RDFa may benefit web accessibility as more information is available to assistive technology.[12]

the purpose of RDFa was always to provide a way to add a metadata to any XML-based language.

RDFa (or Resource Description Framework - in - attributes) is a set of extensions to XHTML which is now a W3C Recommendation. RDFa uses attributes from XHTML's meta and link elements, and generalises them so that they are usable on all elements. This allows annotating XHTML markup with semantics. A simple mapping is defined so that RDF triples may be extracted.
The W3C RDF in XHTML Taskforce is also working on an implementation for non-XML versions of HTML.[1] The primary issue for the non-XML implementation is how to handle the lack of XML namespaces.
The RDFa community runs a wiki to host tools, examples, and tutorials.[2]
