What is the purpose of the MutableData NFS emulation fetch() and how does it differ from open()?
EDIT: I’ve partly answered my own question…
fetch() gets an NFS file object if it exists, while create() is used to get one for a new file.
After that, you can use open() etc.
So my remaining question is can fetch() be used and then allow access to file metadata?
@happybeing, so as you’ve seen. fetch simply returns the File object. whereas open can be used to open and modify a file (using the openMode argument):
CONSTANTS.NFS_FILE_MODE_OVERWRITE: Replaces the entire content of the file when writing data.
CONSTANTS.NFS_FILE_MODE_APPEND: Appends to existing data in the file.
CONSTANTS.NFS_FILE_MODE_READ: Open file to read.

fetch()be used and then allow access to file metadata?
Yup, so fetch() should return a File object: http://docs.maidsafe.net/safe_app_nodejs/#file
Such that you could do:
// myfile is a previously fetched File object.
console.log( myfile.modified ); // date <myfile> was modified in UTC
