Method and system for orchestration of content processing in mobile delivery frameworks
A method and system for coordinating content processing in a mobile delivery framework, the method having the steps of embedding, within a metadata envelope associated with content, external references to external enablers; and inserting content processing coordination rules into the metadata envelope.
1. A method for coordinating content processing in a mobile delivery framework comprising the steps of:
embedding, within a metadata envelope associated with content, external references to external enablers and metadata for a delivery enabler that is different from the external enabler; and
inserting, into the metadata, content processing coordination rules for engaging the functionality of the external enablers for processing the content by the delivery enabler.
2. The method of claim 1 , wherein the content processing coordinating rules are an extensible mark-up language (XML) packaged state chart.
3. The method of claim 2 , wherein the XML packaged state chart comprises a function block with embedded layers.
4. The method of claim 3 , wherein the embedded layers comprise a first layer defining common XML elements; a second layer defining metadata for a delivery enabler having bindings to external enablers; and a third layer defining metadata for external enablers.
5. The method of claim 4 , wherein the third layer is opaque to the delivery enabler.
6. The method of claim 4 , wherein the second layer comprises expressions, instructions or parameters having a predefined behaviour including binding of the expressions, instructions or parameters onto functions of the external enabler.
7. The method of claim 4 , wherein the first layer is referenced by a namespace defining XML syntax for a state chart representation language.
8. The method of claim 3 , wherein the function block contains one or more of:
a state identifier; a guard expression; an external service identifier; an action verb; a
parameter; and a state transition.
9. The method of claim 8 , wherein the action verb is used to map coordination instructions to enabler functions.
10. The method of claim 9 , wherein the mapping is performed by a metadata interpretation layer.
11. The method of claim 8 , wherein the state transition is based on a result received from using an action verb to invoke an external function.
12. The method of claims 1 , wherein the external references are namespace declarations for external services.
13. The method of claim 12 , wherein the external services are selected from the group consisting of a presence service, a location service, a content screening service, and a compression service.
14. The method of claim 1 , wherein said inserting step defines schemas for external enablers within an element for a processing state.
15. A system for coordination of content processing comprising:
a content provider, said content provider adapted to embed external references to external enablers and metadata for a delivery enabler inside mobile content delivery metadata associated with content supplied by said content provider, and to insert into the metadata for a delivery enabler content processing coordination rules in order to engage the functionality of the referenced external enablers for processing the content by the delivery enabler;
a content delivery enabler comprising:
a delivery server, said delivery server adapted to process metadata directed to said delivery server; and
a delivery client, said delivery client adapted to process metadata directed to said delivery client;
external enablers adapted to process content based on the content processing coordination rules through said content delivery enabler; and
a content client adapted to consume content from the content provider.
16. A content package comprising:
content; and
a metadata envelope, the metadata envelope comprising external references to external enablers and metadata for a deliver enabler, the metadata for a delivery enabler including content processing coordination rules embedded therein for engaging a functionality of the external enablers for processing the content by the delivery enabler.
17. The content package of claim 16 , wherein the content processing coordinating rules are an extensible mark-up language (XML) packaged state chart.
18. The content package of claim 17 , wherein the XML packaged state chart comprises a function block with embedded layers.
19. The content package of claim 18 , wherein the embedded layers comprise a first layer defining common XML elements; a second layer defining metadata for a delivery enabler having bindings to external enablers; and a third layer defining metadata for external enablers.
20. The content package of claim 19 , wherein the third layer is opaque to the delivery enabler.
21. The content package of claim 19 , wherein the second layer comprises expressions, instructions or parameters having a predefined behaviour including binding of the expressions, instructions or parameters onto functions of the external enabler.
22. The content package of claim 19 , wherein the first layer is referenced by a namespace defining XML syntax for a state chart representation language.
23. The content package of claim 18 , wherein the function block contains one or more of: a state identifier; a guard expression; an external service identifier; an action verb; a parameter; and a state transition.
24. The content package of claim 23 , wherein the action verb is adapted to be used to map coordination instructions to enabler functions.
25. The content package of claim 16 , wherein the external references are namespace declarations for external services.
26. The content package of claim 25 , wherein the external services are selected from the group consisting of a presence service, a location service, a content screening service, and a compression service.
27. The content package of claim 16 , further comprising schemas for external enablers within an element for a processing state.
