This document describes an approach for creating packages of files for use on the web. The approach is to package them using a new application/package media type. To access packages related to other files on the web, clients that understand packages of files look for a Link header or (in HTML documents) a <link> element with a new link relation of package. Other formats may define format-specific mechanisms for locating related packages.
