Host context framework

1. A computer-implemented method, comprising:

detecting a context event for a host item object;

retrieving a host context for said host item object, wherein said host context comprises at least one object associated with said host item object;

reading behavior information for said host item object from a catalog associated with said context event and said host context, said reading of behavior information responsive to said detection of said context event, said behavior information comprising behavior operations representing a set of operations performed for said host item object for said host context and behavior definitions for said host item object, said behavior definitions representing a custom service, a data source, and a user interface element for said host item object for said host context;

translating said behavior information into object manager calls for multiple object managers; and

performing operations for said host item object in accordance with said behavior information using said object manager calls.

2. The computer-implemented method of claim 1 , comprising creating said host context by associating multiple objects with said host item object.

3. The computer-implemented method of claim 1 , comprising associating a custom service, a data source, or a user interface element with said host item object to form said host context.

4. An article comprising a storage medium containing instructions that if executed by a processor enable a system to:

detect a context event for a host item object;

retrieve a host context for said host item object, wherein said host context comprises at least one object associated with said host item object;

read behavior information for said host item object from a catalog associated with said context event and said host context, said reading of behavior information responsive to said detection of said context event, said behavior information comprising behavior operations representing a set of operations performed for said host item object for said host context and behavior definitions for said host item object, said behavior definitions representing a custom service, a data source, and a user interface element for said host item object for said host context;

translating said behavior information into object manager calls for multiple object managers; and

perform operations for said host item object in accordance with said behavior information using said object manager calls.

5. The article of claim 4 , further comprising instructions that if executed enable the system to create said host context by associating multiple objects with said host item object.

6. The article of claim 4 , further comprising instructions that if executed enable the system to associate a custom service, a data source, or a user interface element with said host item object to form said host context.

7. The article of claim 4 , further comprising instructions that if executed enable the system to embed data in said host item object in accordance with said host context.

8. An apparatus, comprising:

a client device having a processor operative to execute a host application program with multiple host item objects and a host context manager to manage multiple host contexts corresponding to said host item objects, each of said host contexts corresponding to a host item object and comprising at least one object associated with said host item object, said host context manager to create a host context for each host item object, and perform operations for each host item object in accordance with said corresponding host context;

said processor further operative to execute a catalog manager having a catalog of behavior information for each host context, said catalog manager to read behavior information for a host item object from said catalog, said reading of behavior information responsive to a detection of a context event, said behavior information comprising behavior operations representing a set of operations performed for said host item object for said host context and behavior definitions for said host item object, said behavior definitions representing a custom service, a data source, and a user interface element for said host item object for said host context;

a behavior interpreter to translate behavior information into object manager calls for multiple object managers; and

said host context manager to perform operations for a host item object in accordance with said corresponding behavior information using said object manager calls.

9. The apparatus of claim 8 , comprising a context cache to create a host context by associating a custom service, a data source, or a user interface element with a host item object to form said host context.

10. The apparatus of claim 8 , comprising a host integration manager to detect an event for a host item object, request a host context corresponding to said host item object from said host context manager, and activate said host context.
