Goal: A beta for Drupal 8 core is just around the corner and in order to make sure that the core Conditions API & Context APIs fit the requirements of the Rules module, development has to start now!
Deliverables of Milestone 1:
Rules core engine & plug-in types (Services-based architecture, interfaces, tests)
Align Rules condition & action APIs with Drupal 8 core (Dynamic action parameters & context variables)
Parameter configuration & Context mapping
Parameter value processing logic (Data processor plug-ins & Input tokens)
