v0.5.0

WLDT v0.5.0

WLDT v0.5.0 introduces significant enhancements to the Digital Twin framework, emphasizing flexible resource management and a modular logging system. This release enables runtime-configurable resources that can be managed internally by Digital Twin logic and accessed externally via a customizable Management Interface. The new logging layer has been designed to make the library independent from external logging frameworks while allowing developers to fully customize how logs are generated and which logging libraries to use.

Resource Management

New classes introduce a unified, runtime-configurable resource model for Digital Twins (DTs). Resources can be managed internally by DT logic and accessed or updated externally through an abstract Management Interface. The system supports CRUD operations, observers for change notifications, and flexible integration with protocols like REST, MQTT, or gRPC. Key classes include ManagedResource, ResourceManager, ResourceRequest, ResourceResponse, and ManagementInterface. Resources can be dynamically configured at startup or during runtime, enabling adaptable DT behavior and external interaction.

Logging

WLDT now provides a modular logging layer designed for flexibility and easy integration. Developers can use the default console-based logger or implement custom loggers through the WldtLogger, WldtLoggerFactory, and WldtLoggerProvider interfaces. This layer supports multiple log levels, timestamped output, and can be seamlessly replaced or extended to integrate with frameworks like SLF4J, Log4j, or Logback without changing core DT code.
