I think my interest here is more in the JSON schema, and I think that's the more important piece for consolidating tools around a common standard in the long run. I've pushed up an RFC patch with a proposed schema and example layer JSON file to review. It would be nice if the script outlined here didn't have to be generated from bblayers and was a static script that could operate on any JSON file, since that is more generally useful; it would also be a good starting point for a generic layer setup tool that we can point users to and can be replaced by something more comprehensive (like what Richard outlines) later without having to change the actual layer data (the JSON). Or put another way, I'd prefer the data be kept separate from the code. Note that my schema is missing the "is_bootstrap" option yours has; I wasn't quite clear if that meant anything other than "don't fetch this layer by default"? > > Alex > > >
