XML Schema Code Generator for Universal API Development
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for implementing XML/XML schema description do not allow effective or universal code generation, limiting their use in application programming interfaces (APIs).
Innovation Solution
A computer-implemented method for generating code from an XML schema description, which includes receiving an XML schema description, computing a model with corresponding model elements, and generating computing code for various target environments, optionally creating an object-oriented model and application programming interfaces (APIs) for use in these environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional XML schema description systems are used, then XML data can be encoded and processed, but effective and universal code generation for APIs is not enabled
Solution Approach 1:
The patent creates a universal code generation system that works across multiple programming languages and target environments. The schema description model serves as a language-agnostic intermediate representation that can be transformed into code for different languages (Java, C#, Python, etc.), enabling one schema to generate universal, multi-platform code rather than requiring separate processing for each language.
Solution Approach 2:
The patent introduces a schema description model as an intermediary layer between the XML schema and the target code. This model acts as a mediator that captures the essential structure and semantics of the XML schema in a way that can be systematically transformed into various programming languages, bridging the gap between schema definition and code generation.
2Adaptability or versatility
If code generation is limited to specific environments, then implementation complexity is reduced, but versatility across target computing environments is restricted
Solution Approach 1:
The patent segments the code generation process into distinct, modular components: XML schema parsing, schema description model construction, and target code generation. Each component is independent and can be developed, maintained, and extended separately. The schema description model itself is segmented into discrete elements (complex types, simple types, elements, attributes) that map systematically to code structures in different languages.
Solution Approach 2:
The schema description model serves as a universal intermediate representation that maintains compatibility across multiple target environments. By defining a language-neutral model structure that captures the essential semantics of XML schemas, the system achieves cross-environment compatibility without requiring environment-specific processing logic in the core generation engine.
3Productivity
If manual code writing is required for API implementation, then code precision and control are maintained, but development time and effort increase
Solution Approach 1:
The patent performs preliminary action by automatically generating boilerplate code, data structure definitions, and API skeletons from the schema description model. This preliminary code generation handles the routine, error-prone aspects of manual coding, providing a solid foundation that developers can then refine and customize. The generated code includes proper type definitions, validation logic, and method stubs that ensure accuracy from the start.
Solution Approach 2:
The system incorporates feedback mechanisms where the generated code can be validated against the original schema description, ensuring accuracy. The schema description model itself serves as a feedback reference, allowing the system to verify that generated code correctly represents the intended data structures and constraints, reducing errors that would require manual correction.
Data Source
AI summary
A method, a system, and a computer program product for generating code from an XML schema description. A source extendible markup language (XML) schema description for an object is received. Based on the received XML schema description, a XML schema description model having a plurality of model elements is computed. Each model element in the plurality of model elements corresponds to an element in the XML schema description for the object. Based on the computed XML schema description model, a computing code for implementation in a plurality of target computing environments is generated.
