A plan is underway for building block registers to be created for different governance domains and evolution processes.
The BuildingBlocks processing tools have a register import configuration and a bblocks:// resolver that allows for bblocks to be developed in one context then migrated to a new one.
The various status semantics need to be defined/explained in accordance with this process, which needs to be established.
@dr-shorthair and @rob-metalinkage are actively working to develop this proposal, and plan to prepare appropriate draft P&P to support a robust bblock development, testing and publishing cycle.
