Abstract

A method, apparatus, and article of manufacture for generating a Markup-based Graphical User Interface (application) within extensible application framework and links to enterprise resources based on variety of XML Schema languages such as DTD, SOX, and XSDL. XML Schemas provide a description of application data structures and are used to generate automatically an application interface allowing a user to display and modify conformant data via a web browser or mobile device. While XML Schemas define generic data structure, application specific information is delivered using Schema Adjuncts.

Claims

1. A computerized method for generating a Markup-based Graphical User Interface (application), comprising the steps of:

(a) modeling generic application metadata with at least one of extensible Markup Language (XML) Schema languages;

(b) using Schema Annotations (Schema Adjuncts) for definition of application-specific features;

(c) processing said at least one of XML Schema languages into Unified Abstract Schema Interfaces and representing them further with Unified Abstract Schema Interfaces;

(d) analyzing application data and merging said application data with XML Schema information to produce one or more conceptual Extended Document Object Model (ExDOM) trees;

(e) processing at least one conceptual ExDOM trees that encapsulate data conformant to XML Schemas definitions by applying ‘

Output Components’

algorithms, which are instantiated as objects within an object framework, wherein the object framework provides a layered processing model that corresponds to application views, XML Schema definitions and data defined and stored in the underlying data storage; and

(f) generating one or more display forms and reports, wherein said display forms and reports serve as Graphical User Interface to create, display and modify the data conformant to XML metadata definitions.

5. The method of claim 1, wherein said generic application metadata is conceptually merged with Data-Level information into an ExDOM tree or ExDOM.

6. The method of claim 1, wherein said “

9. The method of claim 1, wherein the display forms are selected from a group comprising input forms and reports.

10. The method of claim 9, wherein the said input forms and reports include hidden commands that are used to construct specific server-side requests automatically after a user has submitted client-side actions.

11. The method of claim 10, further comprising the steps of automatic server-side dispatching and executing a set of commands by dedicated Command Processors.

12. The method of claim 11, wherein a custom Command Processor could be registered to execute custom processing including enterprise resources access.

13. The method of claim 11, wherein display forms and reports containing hidden commands are generated automatically as a response to user actions.

14. The method of claim 6, wherein said ExDOM tree is constructed dynamically on an “

as-needed”

basis using a lazy loading process while being processed by various Output Components algorithms.

15. A computerized apparatus for generating WEB applications, comprising:

(a) a computer with a WEB server;

(b) dynamic processor means, performed by the computer, for processing various XML Schema languages into Unified Abstract Schema Interfaces and representing them further with the Unified Abstract Schema Interfaces;

(c) dynamic processor means, performed by the computer, for analyzing application data and merging it with Schemas information to produce a conceptual ExDOM tree; and

(d) dynamic processor means, performed by the computer, for further processing of one or more conceptual ExDOM trees that encapsulate data conformant to XML Schemas definitions by applying special algorithms called Output Components which are instantiated as objects in an object framework, wherein the object framework provides a layered processing model that corresponds to application views, XML Schema definitions, and data defined and stored in the underlying data storage.

(f) dynamic processor means, performed by the computer, for generating at least one of display forms and reports, wherein said display forms and reports are used to perform at least one of creating, displaying and modifying the data conformant to those definitions provided by said XML Schemas.

16. The apparatus of claim 15, wherein different XML Schemas Languages are parsed into and represented with Unified Abstract Schema Interfaces.
