Abstract
A method of retrieving a plurality of resource fragments from a audio-visual resource that is encoded using a hierarchical addressing model for the class of resources of which the audio-visual resource is a member is disclosed. The method comprises inputting a URI reference () comprising a Universal Resource Identifier () and a complex fragment identifier () comprising a plurality of audio-visual resource specific location steps. Thereafter the method comprises a step of locating the audio-visual resource using the Universal Resource Name, and establishing () a logical representation () of the structure of the audio-visual resource. Then the method iteratively evaluates the fragment identifier location steps () against the logical representation () to resolve the complex fragment identifier () into a set of explicit fragment references () configured to explicitly address each of the plurality of resource fragments.
