Abstract

A method of managing media components is described. The method provides a common archival model utilising a scoping hierarchical relationship defined by metadata associated with data entities. The data entities are persistently held on a storage device and referenced in an abstract manner by the metadata. Management metadata provides details of the history of the actions taken in relation to the content as a data object and content metadata provides information relating to the nature of the content itself.

Claims

1. A method of creating an archive in a content repository system comprising a storage device for a plurality of persistent data entities, each entity having a predetermined level of scope such that within a set of related data entities, the scope of an entity at a higher level encompasses the scope of related entities at a lower level of scope, and an interface linking said storage device to one or more external agents operable to interact with said entities, the method comprising:

establishing a set of entities at a first level of scope including an entity representing particular content and an entity representing metadata illustrative of said particular content,

wherein each said entity includes within its scope a pair of entities at a second lower level of scope, of which pair one entity is indicative of physical data corresponding to a representation made by a said entity of said first level of scope and the other contains management metadata relating to said physical data.

2. A method as claimed in claim 1, including instantiating metadata in accordance with a pre-determined definition for delivery to and retrieval from said pair of entities.

3. A method as claimed in claim 2, including instantiating metadata in accordance with said predetermined definition data stored in said one entity wherein said entity falls within the scope of said entity representing metadata illustrative of said particular content.

4. A computer program stored on a tangible medium and comprising executable code for execution on a computer, said code, when executed, causing said computer to carry out the method according to claim 1.

5. A computer program as claimed in claim 4, wherein said computer program is stored in a computer readable medium.

6. An archival system comprising:

a storage device for a plurality of persistent data entities, each entity having a predetermined level of scope such that within a set of related data entities, the scope of an entity at a higher level encompassing the scope of related entities at a lower level of scope; and

an interface linking said storage device to one or more external agents operable to interact with said entities via a processor, the processor being operable to establish a set of entities at a first level of scope including an entity representing particular content and an entity representing metadata illustrative of said particular content;

wherein each said entity includes within its scope a pair of entities at a second lower level of scope, of which pair one entity is indicative of physical data corresponding to a representation made by a said entity of said first level of scope and the other contains management metadata relating to said physical data.

7. A system as claimed in claim 6, wherein said storage device is adapted to be connected to a network.

8. A system as claimed in claim 7, further including a plurality of said storage devices.

9. A terminal adapted for connection to a network including a storage device for a plurality of persistent data entities, each entity having a predetermined level of scope such that within a set of related data entities, the scope of an entity at a higher level encompassing the scope of related entities at a lower level of scope, and a processor linked to an interface, said terminal comprising:

an agent software process operable to generate a request for delivery to said interface and to receive a response therefrom thereby interacting with said entities, wherein said processor is operable to establish a set of entities at a first level of scope including an entity representing particular content and an entity representing metadata illustrative of said particular content,

wherein each said entity includes within its scope a pair of entities at a second lower level of scope, of which pair one entity is indicative of physical data corresponding to a representation made by a said entity of said first level of scope and the other contains management metadata relating to said physical data.
