1. First ideas on the Register of Registers
Daniele Francioli, Emanuela Epure, Michael Lutz 4th MIWP-6 meeting, 24 April 2015

2. Register of Registers (RoR)
The RoR will only store references to the assets
Each stakeholder has to register its own Registry in the RoR (to reference all of the extended assets)
Each stakeoholder can decide whether to put a specific Register in the federation
In order to register Items coming from a specific Register, that Register shall be registered in the federation
The extension of an Item (or of an entire Register) is simply specified by storing:
the URI of the extended element;
the URI of the extender;
the reference to the Register (or Registry) previously registered in the RoR.
