We are creating a web-based, rule building GUI that allows similar functionality to WebCore but based on Rule API. I’m not going to go into more details at this time since it’s still a PoC and needs additional development work, but it exists.
The functionality in the rule builder and near-term roadmap for the Rule API are based on an extensive metadata analysis of active WebCore pistons, an analysis of the core functional needs of the most popular SmartApps, and the feedback we’ve received from the community.
This is also in the works and will be made available before anything happens to WebCore. There will likely be some manual work involved for users (i.e. post the converted JSON to Rule API using the rule builder) but it is planned to be minimal and straightforward.
