Abstract

A system and method are disclosed for generating an application programming interface (API) comprising parsing a schema defining a description language data structure, automatically creating an accessible data structure reflecting all relationships depicted in the parsed schema, and automatically generating code for at least one function based on the parsed schema, wherein the code is based on accessing the accessible data structure.

Claims

1. A method for generating an application programming interface (API) comprising:

parsing a schema defining a description language data structure;

automatically creating an accessible data structure reflecting all relationships depicted in said parsed schema; and

automatically generating code for at least one function based on said parsed schema, wherein said code is based on accessing said accessible data structure.

2. The method of claim 1 further comprising:

automatically creating a set of instructions to use said at least one function.

3. The method of claim 1 further comprising:

standardizing a naming convention for said at least one function.

4. The method of claim 1 wherein said description language data structure comprises one of:

Extensible Markup Language (XML); and

Standard Generalized Markup Language (SGML).

5. An automatic application programming interface (API) generator comprising:

a parser for parsing a descriptor document describing an organization of a description language;

an intermediate data generator for automatically creating a data structure preserving all relationships between said data as shown in said descriptor document; and

a code generator for automatically generating a logic function exposing said organization to a developer using said data structure.

6. The automatic API generator of claim 5 further comprising:

a documentation generator for automatically creating documentation about the use of said logic function.

7. The automatic API generator of claim 6 wherein said documentation includes:

definitions explaining a function of said logic function;

instructions disclosing parameters used in said logic function; and

identifications of objects returned by said logic function.

8. The automatic API generator of claim 5 further comprising:

a naming table accessible by said code generator for naming said automatically generated logic function.

9. The automatic API generator of claim 8 wherein said naming table is standardized to produce consistent names for logic functions having similar capabilities.

10. The automatic API generator of claim 5 wherein said code generator generates code in a computer programming language.

11. The automatic API generator of claim 10 wherein said computer programming language is selected from a group comprising:

JAVA™

;

C/C++;

Perl;

C#™

;

J#™

;

SmallTalk™

;

Pascal;

Modula;

PYTHON; and

VISUAL BASIC.

12. A computer program product having a computer readable medium with computer program logic recorded thereon, said computer program product comprising:

code for parsing an XML schema;

code for automatically creating a data structure representing all data relationships shown in said XML schema; and

code for automatically generating code for one or more classes based on a structure discovered in said parsed XML schema.

13. The computer program product of claim 12 further comprising:

code for automatically generating instructive documentation for said one or more classes.

14. The computer program product of claim 12 further comprising:

code for maintaining a standardized naming convention for use in conjunction with said code for automatically generating code.

15. The computer program product of claim 12 wherein said code for automatically generating said code generates code in a computer programming language.

16. The computer program product of claim 15 wherein said computer programming language is selected from a group comprising:

JAVA™

;

C/C++;

Perl;

C#™

;

J#™

;

SmallTalk™

;

Pascal;

Modula;

PYTHON; and

VISUAL BASIC.

17. An application programming interface (API) generator comprising:

a parser for automatically parsing a schema, said schema representing a domain format;

a code generator for automatically generating an API using said parsed schema; and

a data structure generator for automatically generating a data representation of said domain format of said schema.

18. The API generator of claim 17 further comprising:

an automatic documentation generator for generating a set of instructions for using said API.

19. The API generator of claim 17 further comprising:

a list of names for implementing a standardized naming convention for said API.

20. The API generator of claim 17 wherein said code generator generates code in a computer programming language.

21. The API generator of claim 20 wherein said computer programming language is selected from a group comprising:

JAVA™

;

C/C++;

Perl;

C#™

;

J#™

;

SmallTalk™

;

Pascal;

Modula;

PYTHON; and

VISUAL BASIC.
