Abstract

A method of automatically consuming and processing web services includes parsing a first document describing a web service to identify a first set of attribute-value pairs describing a function offered by the web service and a second set of attribute-value pairs specifying instructions for processing result data returned by the function for rendering in a user interface element; constructing an invocation request object for invoking the first function based upon the first and second sets of attribute-value pairs; and processing the result data returned by the first function based upon the second set of attribute-value pairs to generate a set of code executable to render a presentation of the result data in the user interface element. The second set of attribute-value pairs includes a first attribute-value pair specifying a data type for the result data and a second attribute-value pair specifying a first instruction for processing the result data.

Claims

1. A method of automatically consuming and processing web services, the method comprising:

parsing a first document describing a deployed web service by a processor to identify a first set of attribute-value pairs describing a first function offered by the web service and a second set of attribute-value pairs specifying instructions for processing result data returned by the first function for rendering in a user interface element implemented by a web service client, the second set of attribute-value pairs including a first attribute-value pair specifying a data type for the result data returned by the first function and a second attribute-value pair specifying a first instruction for processing the result data returned by the first function;

constructing an invocation request object for invoking the first function based upon the first and second sets of attribute-value pairs; and

processing the result data returned by the first function based upon the second set of attribute-value pairs to generate a set of code executable by the web service client to render a presentation of the result data returned by the first function in the user interface element.

2. The method of claim 1, wherein the first instruction for processing the result data returned by the first function specified by the second attribute-value pair specifies a rendering format for the result data returned by the first function, and wherein the second set of attribute-value pairs further includes zero or more attribute-value pairs specifying details for rendering the result data returned by the first function based upon the rendering format.

3. The method of claim 2, wherein the rendering format specified by the first instruction is selected from table, image, list, hyperlink, and text format.

4. The method of claim 3, wherein the rendering format specified by the first instruction is a table format, and wherein the zero or more attribute-value pairs specifying details for rendering the result data returned by the first function based upon the rendering format include a third attribute-value pair specifying where column data is located within the result data returned by the first function, a fourth attribute-value pair specifying the column header names to be used to render the result data, and a fifth attribute-value pair specifying where row data is located within the result data returned by the first function.

5. The method of claim 1, wherein the first instruction for processing the result data returned by the first function specified by the second attribute-value pair specifies that a data type of the result data returned by the first function is included in the result data returned by the first function, and further comprising processing the result data returned by the first function to identify a third attribute-value pair specifying a rendering format for the result data returned by the first function and zero or more attribute-value pairs specifying details for rendering the result data returned by the first function based upon the rendering format.

6. The method of claim 5, wherein processing the result data returned by the first function to generate a set of code executable by the web service client to render a presentation of the result data returned by the first function in the user interface element is further based upon the third attribute-value pair specifying a rendering format for the result data returned by the first function and the zero or more attribute-value pairs specifying details for rendering the result data returned by the first function based upon the rendering format.

7. The method of claim 1, wherein the data type for the result data returned by the first function specified by the first attribute-value pair is selected from XML, comma-separated values, JSON, HTML, and text.

8. The method of claim 7, wherein the web service client is a web browser, wherein the user interface element is a web page, and wherein the set of code executable by the web service client to render a presentation of the result data returned by the first function is written in HTML.

9. The method of claim 8, further comprising providing the invocation request object to the web browser for the web browser to use in invoking the first function, and receiving the result data returned by the first function upon the result data being retrieved by the web browser.

10. The method of claim 8, further comprising adding the set of code executable by the web service client to render the presentation of the result data returned by the first function to a Document Object Model (DOM).

11. The method of claim 10, further comprising executing the set of code to render the presentation of the result data returned by the first function in the web page.

12. The method of claim 10, wherein the DOM document includes a respective set of code for rendering a separate presentation for the result data returned by each of a plurality of web service functions, wherein the first function and each of the plurality of web service functions are provided by information services, and wherein the DOM document is executable by the web service client to render an information mashup of the presentation of the result data returned by the first function and the separate presentation for the result data returned by each of the plurality of web service functions in the web page.

13. The method of claim 12, wherein each of the plurality of web services is implemented within a distributed system having a Service-Oriented Architecture.

14. The method of claim 1, wherein processing the result data returned by the first function to generate the set of code executable by the web service client to render the presentation of the result data returned by the first function is further based upon the first set of attribute-value pairs such that the set of code includes a set of information accessible by the web service client to perform periodic invocations of the first function and dynamically update the set of code based upon the result data returned by the first function for each periodic invocation of the first function.

15. A non-transitory computer-usable medium having computer readable instructions stored thereon for execution by a processor to perform a method of automatically consuming and processing web services, the method comprising:

parsing a first document describing a deployed web service by a processor to identify a first set of attribute-value pairs describing a first function offered by the web service and a second set of attribute-value pairs specifying instructions for processing result data returned by the first function for rendering in a user interface element implemented by a web service client, the second set of attribute-value pairs including a first attribute-value pair specifying a data type for the result data returned by the first function and a second attribute-value pair specifying a first instruction for processing the result data returned by the first function;

constructing an invocation request object for invoking the first function based upon the first and second sets of attribute-value pairs; and

processing the result data returned by the first function based upon the second set of attribute-value pairs to generate a set of code executable by the web service client to render a presentation of the result data returned by the first function in the user interface element.

16. A data processing system comprising:

at least one processor;

a random access memory for storing data and programs for execution by the at least one processor; and

computer readable instructions stored in the random access memory for execution by the at least one processor to perform a method of automatically consuming and processing web services, the method comprising;

parsing a first document describing a deployed web service to identify a first set of attribute-value pairs describing a first function offered by the web service and a second set of attribute-value pairs specifying instructions for processing result data returned by the first function for rendering in a user interface element implemented by a web service client, the second set of attribute-value pairs including a first attribute-value pair specifying a data type for the result data returned by the first function and a second attribute-value pair specifying a first instruction for processing the result data returned by the first function;

constructing an invocation request object for invoking the first function based upon the first and second sets of attribute-value pairs; and

processing the result data returned by the first function based upon the second set of attribute-value pairs to generate a set of code executable by the web service client to render a presentation of the result data returned by the first function in the user interface element.
