Abstract

An aspect of this invention is a method that includes receiving input data from an application. The input data includes information descriptive of at least one field. The method further includes processing the input data to form an array composed of legal data for the at least one field. The array is formed by merging a result of processing syntactic constraints and a result of processing semantic constraints. The method further includes outputting the array to the application. A system for performing the method is also described, as is a computer program product that can be used to execute the method.

First claim

What is claimed is:

1. A method comprising:
receiving first data at a service from a client application, the received first data comprising information descriptive of at least one field of a data assemblage used by the client application and partial data having at least one value that constrains the at least one field, where the data assemblage represents a form containing the at least one field that is to be displayed by the client application to a user with a user interface of the client application, the at least one field being one in which the user of the client application will enter user data into the displayed form to be validated by the client application;
processing the received first data at the service to form an array comprised of legal data for the at least one field, the array being formed by merging a result of processing syntactic constraints to define field type information for the at least one field and a result of processing semantic constraints to define legal values for the at least one field based at least on the partial data;
outputting the array formed by the merging of the result of processing syntactic constraints and the result of processing semantic constraints from the service to the client application such that the client application configured to generate the form based on both the field type information and the legal values in the array for the at least one field such that the client application is enabled to validate user data that is subsequently entered by the user of the client application into the at least one field; and
where in response to the client application iterating over a workflow associated with the outputted array formed by the merging of the result of processing syntactic constraints and the result of processing semantic constraints, receiving at the service from the client application a request for more legal data for at least one co-constrained field of the form that is displayed to the user that was not previously specified by the client application in the received first data.

2. The method of claim 1 , further comprising parsing the received first data using an XML, parser to derive a data XML instance.

3. The method of claim 2 , where the data XML instance is used, when processing semantic constraints, in conjunction with a facts XML instance obtained from a facts database in order to infer if an inter-dependency is present.

4. The method of claim 1 , where the array that is output to the client application is formed so as to complement the legal values for the at least one field with results of constraints on at least one of data values, (inter-)dependencies, co-constraints and data state transitions.

5. A computer program product embodied on a non-transitory computer-readable medium, where execution of the computer program product results in performance of the method as claimed in claim 1 .

6. The method of claim 1 , wherein the partial data comprises an indication that the at least one field is dependent on at least one other field contained in the form.

7. The method of claim 1 , wherein the at least one field comprises at least one of:
a text field;
a number field; and
a Boolean field.

8. A non-transitory computer-readable medium that contains computer program instructions, the execution of the computer program instructions by at least one data processor results in performance of operations that comprise:
receiving first data at a service from a client application, the received first data comprising information descriptive of at least one field of a data assemblage used by the client application and partial data having at least one value that constrains the at least one field, where the data assemblage is comprised of a form containing the at least one field that is to be displayed by the client application to a user with a user interface of the client application, the at least one field being one in which the user of the client application will enter user data into the displayed form to be validated by the client application;
processing the received first data at the service to form an array comprised of legal data for the at least one field, the array being formed by merging a result of processing syntactic constraints to define field type information for the at least one field and a result of processing semantic constraints to define legal values for the at least one field based at least on the partial data; and
outputting the array formed by the merging of the result of processing syntactic constraints and the result of processing semantic constraints from the service to the client application such that the client application is configured to generate the form based on both the field type information and the legal values in the array for the at least one field such that the client application is enabled to validate user data that is subsequently entered by the user into the at least one field;
where in response to the client application iterating over a workflow associated with the outputted array formed by the merging of the result of processing syntactic constraints and the result of processing semantic constraints, receiving at the service from the client application a request for more legal data for at least one co-constrained field of the form that is displayed to the user that was not previously specified by the client application in the received first data.

9. The computer-readable medium of claim 8 , further comprising an operation of parsing the received first data using an XML parser to derive a data XML instance.

10. The computer-readable medium of claim 9 , where the data XML instance is used, when processing semantic constraints, in conjunction with a facts XML instance obtained from a facts database in order to infer if an inter-dependency is present.

11. The computer-readable medium of claim 8 , where the array that is output to the client application is formed so as to complement the legal values for the at least one field with results of constraints on at least one of data values, (inter-)dependencies, co-constraints and data state transitions.

12. The computer-readable medium of claim 8 , wherein the partial data comprises an indication that the at least one field is dependent on at least one other field contained in the form.

13. The computer-readable medium of claim 8 , wherein the at least one field comprises at least one of:
a text field;
a number field; and
a Boolean field.

14. A data processing system, comprising:
at least one data processor connected with at least one memory that stores computer program instructions, the at least one data processor comprising a part of a service;
at least one interface connected with the at least one data processor and configured for conducting bidirectional communications with a client application via at least one network;
said at least one data processor operating under control of the computer program instructions to receive first data at the service from the client application via the at least one interface, the received first data comprising information descriptive of at least one field of a data assemblage used by the client application and partial data having at least one value that constrains the at least one field, where the data assemblage is comprised of a form containing the at least one field that is to be displayed by the client application to a user with a user interface of the client application, the at least one field being one in which the user of the client application will enter user data into the displayed form to be validated by the client application;
said at least one data processor opera
