One approach is to bookmark a file and use a bookmark's annotation to record 
the metadata.

If you use Bookmark+ then:

You can also use tags, instead of or in addition to an annotation.

You can also use an autofile bookmark, which has the same name as the file.  
This is just a wrapper around a file or directory: a way to attach meta 
information (such as tags or an annotation) to it.  But you can use an autofile 
bookmark much as you would use a file or directory.
