Design document for Node Interface Definition Language (IDL)

[artivis]

Design document for the 'Node Interface Definition Language (IDL)',

a simple and standardized manner to export the complete interface (action/message/parameter/service) of node(s) in a package.

Initially discussed within the Security WG, this proposal is not security-related only. Security features and tooling building on top of this will be proposed in a subsequent document.
