- '''An abstraction over the /baserock metadata directory.
-
- This allows methods of iterating over it, and accessing it like
- a dict.
-
- The /baserock metadata directory contains information about all of
- the chunks in a built system. It exists to provide traceability from
- the input sources to the output.
-
- If you create the object with smd = SystemMetadataDir('/baserock')
- data = smd['key'] will read /baserock/key.meta and return its JSON
- encoded contents as native python objects.
-
- smd['key'] = data will write data to /baserock/key.meta as JSON
-
- The key may not have '\0' characters in it since the underlying
- system calls don't support embedded NUL bytes.
-
- The key may not have '/' characters in it since we do not support
- morphologies with slashes in their names.
