[chef] Data bags as JSON files in subdirectory structure

[Russell Bateman < >]

I'm a little confused by the examples I see of data bags, in http://docs.opscode.com/essentials_data_bags.html and elsewhere.

I keep all my Chef stuff in a filesystem (and Git) thus:

cookbooks
nodes
roles

This has all be working very well. Growing up to be man in Chef and learning data bags, I plan to add to this

data_bags
    admins
        charlie.json

...and not

data_bags
    _admins
        _charlie.json

I see some mention of substructure in the doc, but it's confusing; sometimes subdirectories and filenames are prefixed with an underscore while there's no mention of it in the outer discussion, such as the following command, but I wish to avoid underscores unless significant or best practice. Examples of telling my Chef server about this data bag tend to suggest using

knife data bag from file admins data_bags/admins/charlie.json

This is the path in my filesystem, which I commit to Git. Am I missing something here?

Many thanks!
