Abstract

Systems and methods are provided for specifying transformations of JSON objects using other JSON objects. A first object is received specified using JavaScript Object Notation. The first object includes a set of one or more attributes where each attribute is of a predetermined JSON data type and has at least one value. A second object is also received specified using JavaScript Object Notation. The second object includes a set of one or more attributes each corresponding to at least one attribute in the set of attributes of the first object and having at least one value defining one or more transformations. A third object specified using JavaScript Object Notation is generated based on transforming the first object using the second object.

Claims

1. A method for transforming JavaScript Object Notation (JSON) data, the method comprising:

receiving, at a computer, a first object specified using JavaScript Object Notation (JSON), the first object having a set of one or more attributes, each attribute being of a predetermined JSON data type and having at least one value;

receiving, at the computer, a second object specified using JavaScript Object Notation, the second object having a set of one or more attributes each corresponding to at least one attribute in the set of one or more attributes of the first object and having at least one value defining one or more transformations,

wherein receiving, at the computer, the second object comprises receiving an attribute of an object specified using JavaScript Object Notation having a value that defines one or more tests that define whether the one or more transformations are applicable to the first object;

determining, by the computer, a positive evaluation of the one or more tests;

transforming, by the computer, the first object specified using JavaScript Object Notation into a third object specified using JavaScript Object Notation based on the second object specified using JavaScript Object Notation based on the positive evaluation of the one or more tests,

wherein the transforming comprises renaming an attribute of the first object, performing one or more numerical operations with respect to a value of an attribute of the first object, performing one or more string operations with respect to a value of an attribute of the first object, adding one or more attributes to an attribute of the first object which is also an object, or removing one or more attributes from an attribute of the first object which is also an object; and

storing the third object in a storage device associated with the computer.

2. The method of claim 1 wherein receiving, at the computer, the second object comprises receiving an object specified using JavaScript Object Notation having an attribute whose name corresponds to a name of an attribute of the first object.

3. The method of claim 2 wherein receiving the object having the attribute whose name corresponds to the name of the attribute of the first object comprises receiving the attribute as having a same name as the attribute of the first object.

4. The method of claim 2 wherein receiving the object having the attribute whose name corresponds to the name of the attribute of the first object comprises receiving the attribute as having a value that references the name of the attribute of the first object.

5. The method of claim 1 wherein receiving, at the computer, the second object comprises receiving an attribute of an object specified using JavaScript Object Notation having a value that specifies an operation to be applied to either a name of an attribute of the first object or a value of the attribute of the first object.

6. The method of claim 1 wherein receiving, at the computer, the second object comprises receiving an attribute of an object specified using JavaScript Object Notation having a value that specifies a data type of an attribute of the third object corresponding to a transformation of the attribute of the first object.

7. The method of claim 1 wherein receiving, at the computer, the second object comprises receiving an attribute of an object specified using JavaScript Object Notation having a value that specifies a modification to one or more attributes of the first object.

8. The method of claim 1 wherein the one or more tests are defined with respect to one or more attributes of the first object.

9. The method according to claim 1, wherein the first object, the second object and the third object are JSON objects.

10. The method according to claim 1, wherein the second object is a JSON StyleSheet Language (JSL) document.

11. The method according to claim 1, wherein the computer is configured to transform JavaScript Object Notation data.

12. The method according to claim 1, wherein the first object comprises a JSON string.

13. A non-transitory computer-readable medium storing a computer program product executable by a processor of a computer system for transforming JavaScript Object Notation (JSON) data, the non-transitory computer-readable medium comprising:

code for receiving a first object specified using JavaScript Object Notation (JSON), the first object having a set of one or more attributes, each attribute being of a predetermined JSON data type and having at least one value

code for receiving a second object specified using JavaScript Object Notation, the second object having a set of one or more attributes each corresponding to at least one attribute in the set of one or more attributes of the first object and having at least one value defining one or more transformations,

wherein receiving the second object comprises receiving an attribute of an object specified using JavaScript Object Notation having a value that defines one or more tests that define whether the one or more transformations are applicable to the first object;

code for determining a positive evaluation of the one or more tests; and

code for transforming the first object specified using JavaScript Object Notation into a third object specified using JavaScript Object Notation based on the second object specified using JavaScript Object Notation based on the positive evaluation of the one or more tests,

wherein the transforming comprises renaming an attribute of the first object, performing one or more numerical operations with respect to a value of an attribute of the first object, performing one or more string operations with respect to a value of an attribute of the first object, adding one or more attributes to an attribute of the first object which is also an object, or removing one or more attributes from an attribute of the first object which is also an object.

14. The non-transitory computer-readable medium of claim 13 wherein the code for receiving the second object comprises code for receiving an object specified using JavaScript Object Notation having an attribute whose name corresponds to a name of an attribute of the first object.

15. The non-transitory computer-readable medium of claim 14 wherein the code for receiving the object having the attribute whose name corresponds to the name of the attribute of the first object comprises code for receiving the attribute as having the same name as the attribute of the first object.

16. The non-transitory computer-readable medium of claim 14 wherein the code for receiving the object having the attribute whose name corresponds to the name of the attribute of the first object comprises code for receiving the attribute as having a value that references the name of the attribute of the first object.

17. The non-transitory computer-readable medium of claim 13 wherein the code for receiving the second object comprises code for receiving an attribute of an object specified using JavaScript Object Notation having a value that specifies an operation to be applied to either a name of an attribute of the first object or a value of the attribute of the first object.

18. The non-transitory computer-readable medium of claim 13 wherein the code for receiving the second object comprises code for receiving an attribute of an object specified using JavaScript Object Notation having a value that specifies a data type of an attribute of the third object corresponding to a transformation of the attribute of the first object.

19. The non-transitory computer-readable medium of claim 13 wherein the code for receiving the second object comprises code for receiving an attribute of an object specified using JavaScript Object Notation having a value that specifies a modification to one or more attributes of the first object.

20.
