Eclipse Californium (Cf) is an open source implementation of the Constrained Application Protocol (CoAP). It is written in Java and targets unconstrained environments such as back-end service infrastructures (e.g., proxies, resource directories, or cloud services) and less constrained environments such as embedded devices running Linux (e.g., smart home/factory controllers or cellular gateways).
The Eclipse Handly project provides basic building blocks for handle-based models, with an emphasis on language-specific source code models of the underlying Eclipse workspace. It allows creating highly scalable, robust, and thoroughly optimized models similar in design principles to the tried-and-tested Java model of Eclipse Java development tools while reducing programming effort, fostering software reuse, and enabling interoperability.
Handly is designed for flexibility and can be used to create source code models for practically any language, whether general-purpose or domain-specific; it is compatible with any parsing technology. The model implementor has complete control over the model's base-level API, including the ability to implement a preexisting handle-based model API. At the same time, the provided uniform meta-level API establishes a common language and makes it possible for IDE components to work in a generic way with any Handly-based model.
Eclipse Kura offers a Java/OSGi-based container for M2M applications running in service gateways. Kura provides or, when available, aggregates open source implementations for the most common services needed by M2M applications. Kura components are designed as configurable OSGi Declarative Service exposing service API and raising events. While several Kura components are in pure Java, others are invoked through JNI and have a dependency on the Linux operating system.
