AST Schema Definition

[ForestMars]

Context

Following ADR-001 (#12), we need to define the Abstract Syntax Tree (AST) schema that will serve as our intermediate representation between PRD parsing and TypeSpec generation.

Requirements

• Must be able to represent all PRD concepts
• Must be easily transformable to TypeSpec
• Must support validation and error reporting
• Must be versioned
• Must be well-documented

TODO

• Define core AST node types
• Define relationships between nodes
• Create JSON Schema for AST validation
• Document AST structure and usage
• Add examples of AST representation
• Create test cases for AST generation
• Define versioning strategy

Technical Details

• Will be defined in YAML/JSON Schema format
• Must support:
  • Entity definitions
  • Relationships
  • Methods/verbs
  • Properties and types
  • Validation rules
  • Metadata

Acceptance Criteria

• Complete AST schema definition
• Clear documentation of node types
• Example ASTs for common PRD patterns
• Validation rules defined
• Versioning mechanism in place
• Test cases for AST generation
