title: Is there a way to store custom metadata in a Google Drive file?
body: <p>I am writing an rsync utility for Google Drive, but I need a way of storing file system specific data about files in some sort of custom metadata tag.  I don't see anything obvious in the documentation, but wondered if there was some other facility not highlighted in their documentation; like the overloading of some otherwise unused metadata tag.  IndexableText comes to mind, but I have no idea what it is intended use is...</p>
