Abstract

An apparatus for defining a data interchange protocol (DIP) modeling language may include a processor and memory storing executable computer code causing the apparatus to at least perform operations including defining a DIP modeling language specifying data models shared by communication devices. The data models include data specifying criteria to define DIP objects including instances of data. The computer program code may further cause the apparatus to specify features in the data models corresponding to properties or the objects. The features being utilized in part to determine whether properties or objects of a DIP document(s) are valid. The computer program code may further cause the apparatus to evaluate an object(s) of a DIP document(s) to determine whether the object is valid based on analyzing items of data in the data models specifying that objects assigned a type and name are valid. Corresponding methods and computer program products are also provided.

Claims

1. A method comprising:

defining, via a processor, a data interchange protocol modeling language specifying data models shared by one or more communication devices, the data models comprise data specifying criteria to define one or more data interchange protocol objects comprising instances of data;

specifying features in the data models corresponding to (i) properties of the objects or (ii) the objects and defining a property restriction in the data models to designate a restriction for at least one property of the data interchange protocol document, the specified features and the defined property restriction being utilized in part to determine whether one or more properties or objects of at least one data interchange protocol document are valid, wherein the defined property restriction restricts a value of a property type for the at least one property of the data interchange protocol document; and

evaluating at least one object of a data interchange protocol document to determine whether the object is valid based in part on analyzing defined items of data in the data models specifying that objects assigned a type and a name are valid objects.

2. The method of claim 1, wherein, a syntax of the data interchange protocol modeling language comprises a JavaScript Object Notation syntax.

3. The method of claim 2, further comprising:

generating an indication of an error in an instance in which the determination indicates that the object is not assigned a type and name, the error denotes that the data interchange protocol document is invalid, and

wherein the data interchange protocol document is received from one of the communication devices.

4. The method of claim 1, further comprising:

determining whether the at least one property includes the designated restriction to detect whether the property is valid.

5. The method of claim 2, wherein specifying features further comprises:

defining a minimum cardinality in the data models specifying a minimum number of occurrences of at least one property that are required in the data interchange protocol document.

6. The method of claim 5, further comprising:

analyzing the data interchange protocol document to determine whether the data interchange protocol document includes the minimum number of occurrences of the at least one property.

7. The method of claim 2, wherein specifying features further comprises:

defining a maximum cardinality in the data object model specifying a maximum number of occurrences of at least one property that are required in the data interchange protocol document.

8. The method of claim 7, further comprising:

analyzing the data interchange protocol document to determine whether the data interchange protocol document includes the maximum number of occurrences of the at least one property.

9. The method of claim 2, wherein specifying features further comprises:

designating a property of an instance of a data interchange protocol object to intersect with another property of the instance of the data interchange protocol object in the data models to indicate that at least one property of the data interchange protocol document is required to be utilized in conjunction with the another property of the data interchange protocol document.

10. The method of claim 2, wherein specifying features further comprises:

designating a property of an instance of a data interchange protocol object as disjointed with another property in the data models to indicate that at least one property of the data interchange protocol document is unusable in conjunction with the another property of the data interchange protocol document.

11. An apparatus comprising:

at least one processor; and

at least one memory including computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following;

define a data interchange protocol modeling language specifying data models shared by one or more communication devices, the data models comprise data specifying criteria to define one or more data interchange protocol objects comprising instances of data;

specify features in the data models corresponding to (i) properties of the data interchange protocol objects or (ii) the data interchange protocol objects and define a property restriction in the data models to designate a restriction for at least one property of the data interchange protocol document, the specified features and the defined property restriction being utilized in part to determine whether one or more properties or objects of at least one data interchange protocol document are valid, wherein the defined property restriction restricts a value of a property type for the at least one property of the data interchange protocol document; and

evaluate at least one object of a data interchange protocol document to determine whether the object is valid based in part on analyzing defined items of data in the data models specifying that objects assigned a type and a name are valid objects.

12. The apparatus of claim 11, wherein a syntax of the data interchange protocol modeling language comprises a JavaScript Object Notation syntax.

13. The apparatus of claim 12, wherein the memory and computer program code are configured to, with the processor, cause the apparatus to:

generate an indication of an error in an instance in which the determination indicates that the object is not assigned a type and name, the error denotes that the data interchange protocol document is invalid, and

wherein the data interchange protocol document is received from one of the communication devices.

14. The apparatus of claim 11, wherein the memory and computer program code are configured to, with the processor, cause the apparatus to:

determine whether the at least one property includes the designated restriction to detect whether the property is valid.
