| Abstract: |
Techniques for providing information about a current state modeled with multiple attributes is described. The providing of information can include receiving from a first source an indication of an ability to supply values for one of the state attributes of the modeled current state, and supplying to a client a value for the one attribute received from the first source. After the supplying of the value, the providing can include receiving from a second source a value supplying ability for the one attribute and supplying of a value for the one attribute based on values received for the one attribute from the first and second sources. After the supplying of that value, the providing can include receiving from the first source an indication of a value supplying inability for the one attribute and supplying a value for the one attribute received from the second source. |
| Claim: |
We claim:
1. A method in a computer for providing information about a current state that is modeled with multiple attributes, the method comprising: receiving from a first source a first valuefor a first attribute for the state attributes of the modeled current state; receiving from a second source, different from the first source, a second value for the first attribute of the state attributes of the modeled current state, the second valuebeing different from the first value; determining that first and second values exist for the first attribute; in response to the determining, mediating the first and second values supplied from the first and second source based on the first and secondvalues to derive a mediated value for the first attribute; after mediating the mediated value for the first attribute, supplying to the client the mediated value for the first attribute; after the supplying of the mediated value, receiving from thefirst source an indication of an inability to supply values for the first attribute; and after receiving the indication from the first source, supplying to the client a third value for the first attribute received from the second source.
2. The method of claim 1 wherein the receiving of the first value for the first attribute from the first source includes receiving descriptive information about the first value.
3. The method of claim 2 wherein the descriptive information includes a time at which the first value is most accurate.
4. The method of claim 2 wherein the descriptive information includes a confidence factor indicating a likelihood of accuracy of the first value.
5. The method of claim 2 including supplying the descriptive information about the first value to the client.
6. The method of claim 1 wherein the supplying of the mediated value for the first attribute to the client includes supplying an indication of the source from which the mediated value was received.
7. The method of claim 1 further comprising before supplying the mediated value, receiving an indication from the client for a value of the first attribute including an indication of a desired source for the value, and wherein mediating thefirst and second values includes considering the desired source.
8. The method of claim 1 wherein supplying to the client the third value includes supplying the second value.
9. The method of claim 1 including storing the first and second values so that the stored values can be later supplied to clients.
10. The method of claim 1 wherein the first attribute represents information about a user of the computer.
11. The method of claim 1 wherein the first attribute represents information about the computer.
12. The method of claim 1 wherein the first attribute represents information about a physical environment of a user of the computer.
13. The method of claim 1 wherein the first attribute represents information about a cyber-environment of a user of the computer.
14. The method of claim 1 including: after the supplying of the third value that is received from the second source, receiving from the second source an indication of an inability to supply values for the first attribute; and indicating to theclient that the value of the first attribute is not currently available.
15. The method of claim 1 including, after receiving an indication from the client for a value of a second indicated attribute, supplying to the client a value for the second attribute, the second indicated attribute being different from thefirst attribute.
16. The method of claim 15 wherein the supplied value for the second attribute is received from the first source.
17. The method of claim 1 including, after receiving an indication from a second client for a value of a second attribute, supplying to the second client a supplied value for the second attribute.
18. The method of claim 17 wherein the second attribute is the first attribute, and the supplied value is the mediated value.
19.

24. The method of claim 20 including: sending first and second requests to the first or second sources respectively for a value of the first attribute in response to the receiving of the requests from the client; wherein receiving the firstvalue from the first source is in response to the first request; and wherein receiving the second value for the first attribute from the second sources is in response to the second request.
25. The method of claim 1 wherein the first source is at a location remote from the computer, and wherein the indication from the first source of the inability to supply values for the first attribute are based on proximity of the computer tothe location of the first source.
26. The method of claim 1 wherein the first source is software executing on the computer, and wherein the indication from the first source of the inability to supply values for the first attribute are based on availability of input informationto the first source.
27. The method of claim 1 wherein the providing of the information about the modeled current state is performed by an operating system of the computer.
28. The method of claim 1 wherein the providing of the information about the modeled current state is performed by a software module, and including, upon commencement of execution of the software module, commencing execution of multiple sourcesthat are each to supply values for the first attribute.
29. The method of claim 28 wherein the multiple sources that are to be executed are determined based on previous received indications of ability to supply values for the first attribute.
30. The method of claim 1 wherein the first attribute is part of a predefined taxonomy of attributes.
31. The method of claim 1 wherein the state attributes are dynamically defined by sources who indicate an ability to supply values for the defined attributes.
32. The method of claim 1 including receiving from the client an indication of another state attribute and an indication that a source for a value for the indicated another state attribute is to be a same source as for the mediated value forthe first attribute, and selecting a value to be sent to the client for the another state attribute that is received from the same source.
33. The method of claim 1 including receiving from the first source an indication of a group of at least one authorized client, and wherein a value received from the first source is supplied to the client only if the client is one of theauthorized clients.
34. The method of claim 1 wherein the first source includes a group of instructions to be executed to produce a value for the first attribute, and including loading and executing the group of instructions, the loading and executing so that thefirst source can produce the first value.
35. The method of claim 1 wherein receiving of the mediated value by the client prompts the client to present information to a user of the client.
36. A computer-readable memory whose contents cause a computing device to provide information about a current state that is modeled with multiple attributes, by performing a method comprising: receiving from a first source a first value for afirst attribute for the state attributes of the modeled current state; receiving from a second source, different from the first source, a second value for the first attribute of the state attributes of the modeled current state, the second value beingdifferent from the first value; determining that first and second values exist for the first attribute; in response to the determining, mediating the first and second values supplied from the first and second source based on the first and second valuesto derive a mediated value for the first attribute; after mediating the mediated value for the first attribute, supplying to the client the mediated value for the first attribute; after the supplying of the mediated value, receiving from the firstsource an indication of an inability to supply values for the first attribute; and after receiving the indication from the client first source, supplying to the client a third value for the first attribute received from the second source.
37. A computing device for providing information about a current state that is represented with multiple attributes, comprising: a processor the executes computer executable instructions stored in memory to implement the following: an attributemapping module that is capable of receiving from a first source a first value for a first attribute for the state attributes of the modeled current state and a second source, different from the first source, a second value for the first attribute of thestate attributes of the modeled current state, the second value being different from the first value, and that is capable of later determining that first and second values exist for the first attribute; an attribute value receiver module that is capableof receiving values for the first attribute from the first and second sources; a mediator that is capable of mediating the values supplied from the first and second sources to derive a mediated value; and an attribute value supplier module that iscapable of, after mediating the mediated value for the first attribute, and before an indication is received from the second source, supplying to a client a third value for the first attribute received from the first source, after the indications arereceived from the first and second sources, supplying to the client the mediated value for the one attribute based on values received for the one attribute from the first and second source; and after the indication is received from the second source andafter the indication is received from the first source of the inability to supply values for the first attribute, supplying to a client a third value for the first attribute received from the second source.
