[chef] Is there a library that does this already?

[Booker Bense < >]

Before I write it, is there a library that implements anything like
this scheme?

Get values from a databag store in the following way

if item[site_workgroup_node] exists
     return value
else if item[site_workgroup] exists
     return value
else if item[site]
     return value
else
     return nil
end

To implement what I want, I suspect the concatenating hash name will
not work since I want
to put acl's around changing the item value via some kind of front
end. The databags will
probably have to be separate.
