This W3C informational Note details the work of an experimental project which demonstrates how Resource Description Framework (RDF) metadata can be used to describe the content of digitized photos to enable them to be searchable and retrievable over HTTP.

The photo-RDF system described in this paper has three parts to it:

1. Scanning a photo and saving it as a JPEG file

2. Entering the photo's RDF-based metadata and storing it inside the JPEG file

3. Using a Jigsaw-based server-side module which uses HTTP-based content negotiation to serve up either the JPEG image data or its RDF description to an awaiting client or server-based application

The paper also links to a working example of a photo-serving slideshow application that provides a demonstration of this technology in action.
