The key driving force for the release is support for Accessors, which are a technology for making the Internet of Things accessible to a broader community of citizens, inventors, and service providers through open interfaces, an open community of developers, and an open repository of technology. Accessors enable composing heterogeneous devices and services in the Internet of Things (IoT).
This release of Ptolemy includes the CapeCode configuration, which is a development environment and host for applications that use accessors, described at accessors.org. CapeCode provides a block diagram editor for prototyping IoT applications and code generators for deploying those applications on other accessor hosts.
