Json Schema Validator
Esta biblioteca es una herramienta basada en Java para aplicar restricciones de estructura de datos y verificar formatos técnicos contra especificaciones de esquema definidas. Funciona como una utilidad de procesamiento que analiza estructuras de datos complejas mientras gestiona referencias de esquema externas y dependencias circulares.
El motor se distingue por un diseño de procesador inmutable que permite una validación concurrente y segura para hilos sin requerir sincronización externa. Emplea aritmética de precisión arbitraria para evaluar restricciones numéricas, evitando errores comunes de redondeo de punto flotante, y utiliza procesamiento a nivel de carácter para asegurar la validación de cadenas consciente de Unicode para símbolos complejos. Los desarrolladores pueden extender el pipeline central registrando palabras clave personalizadas y manejadores de formato para implementar lógica de negocio especializada.
El proyecto proporciona una gestión integral de esquemas, incluyendo la comprobación de cumplimiento estructural contra meta-esquemas, resolución de dependencias basada en URI y carga de esquemas configurable. Admite informes de error detallados que continúan la validación a través de elementos secundarios incluso después de fallos principales, e incluye una interfaz de línea de comandos para la verificación de datos basada en terminal.
Features
- Procesamiento de JSON - Provides a robust engine for parsing, transforming, and validating complex data structures against defined schema specifications.
- JSON Schema Validation - Validates JSON data against schema specifications with support for version switching and high-precision numeric values.
- Java Validation Libraries - Provides a Java-based tool for enforcing data structure constraints and technical formats using standard schema definitions.
- Schema Reference Resolution - Fetches and processes external schema definitions using various URI schemes while managing custom handlers and detecting circular dependencies.
- Immutable Processors - Performs validation using immutable processors that allow a single instance to be shared safely across multiple concurrent application threads.
- Date and Time Libraries - Verifies date and time strings against international standards with support for variable precision and time zones.
- Numeric Precision Constraints - Enforces numeric precision constraints using arbitrary-precision arithmetic to avoid floating-point inaccuracies.
- Networked Schema Resolvers - Resolves and loads external schema definitions across network protocols while managing URI namespaces.
- High Precision Mathematics - Verifies numeric and string data against strict constraints to prevent rounding errors and encoding issues.
- Unicode Length Validations - Evaluates string constraints using character-level processing to correctly handle complex Unicode symbols.
- Custom Validation Rules - Supports custom validation rules by allowing registration of unique keywords and format attributes.
- Schema Keyword Functions - Allows developers to inject custom logic by registering new keywords and format handlers into the validation pipeline.
- Domain-Specific Validation Rules - Enforces specialized business rules by extending standard validation logic with custom keywords and formats.
- URI Namespace Redirectors - Controls how schemas are retrieved by preloading files, redirecting URI namespaces, and registering custom downloaders for various network protocols.
- Validation Error Reporters - Supports detailed error reporting that continues validation across child elements even after parent failures to ensure comprehensive compliance tracking.
- Arbitrary-Precision Arithmetic - Uses arbitrary-precision arithmetic to evaluate numeric constraints and prevent floating-point rounding errors.
- Constraint-Based JSON Validators - Provides a standalone command-line interface for validating JSON documents against schema requirements.
- Multi-Threaded Batch Processing - Executes thread-safe validation tasks concurrently to maintain high performance during heavy data processing.
- Recursive Schema Resolvers - Resolves external schema dependencies via URI and detects circular references to prevent infinite processing loops.
- Regular Expression Validations - Applies regular expressions to ensure uniform string validation across different computing environments.
- Meta-Schema Validations - Verifies that schema definitions are structurally correct and fully compliant with the requirements of the core meta-schema.
- Immutable State Patterns - Encapsulates validation logic in immutable, thread-safe objects to enable concurrent execution without external synchronization.
- String Format Validators - Validates string values against technical standards including base64, cryptographic hashes, and URI templates.
