Peridot

Peridot is a framework for composed, intelligent and distributed user experiences.

Applications not explicitly designed to interoperate (and possibly implemented in different programming languages) are ephemerally downloaded and dynamically composed to run in a shared context. The framework manages application lifecycle, resources and view hierarchy; and well as context and suggestion infrastructure.

State of Peridot experiences is transparently synchronized across user devices using a distributed offline-first storage system.
