Thanks @lionel.faber it is indeed helpful. I’ve always known that it was feasible to have subcontainers but have never seen it suggested in documentation, discussion or indeed in code before (though that might well exist). Can you point to an RFC or documentation for this that maybe I’ve missed, or say whether it is specified in some private design doc? I’m curious why it had been so hard to discover!
I hadn’t thought of using it as a way to implement an empty folder, but I can see that this is in effect what we get on first creating a Web service - I.e. we get an entry in
_public that points to an empty NFS container.
Things like this could do with being documented along with design guidance, as it is figuring out how to do things like this properly that takes devs a lot of time, and can lead to incompatible implementations.
Thanks very much for your help. I’m inclined not to act on it until it is clear in the API docs, and I’m sure things aren’t likely to change (eg in view of work in API Appendable Data and RDF).
