White Paper - Expanding Multilingual Interoperability in the COGNIT Device Runtime

This white paper explores the evolution of the COGNIT Device Runtime into a production-ready, multi-language framework for the cognitive cloud-edge continuum. Building on the existing Python and C reference implementations, it examines the current architecture, identifies the protocol components that are language-agnostic, and proposes a standardized approach for supporting additional programming languages such as Rust, Go, Java/Kotlin, JavaScript/TypeScript, and C++.

The document covers the runtime's communication model, function serialization mechanisms, integration strategies, security and portability considerations, and best practices for ensuring interoperability across implementations. It also outlines the architectural enhancements required on the server side to enable native execution of functions written in different languages.

Intended for developers, architects, and contributors to the COGNIT ecosystem, this white paper provides a technical roadmap for extending the Device Runtime while preserving its core principles of transparency, adaptability, security, and consistent behavior across heterogeneous cloud-edge environments.
