Subject Re: [vfs] File Metadata
Date Wed, 15 Feb 2006 16:33:42 GMT
The one problem I see with the service API is that if I'm trying to find 
metadata for a FileObject, looking in the service API isn't an obvious 
thing to do.  Most people when they're starting to learn VFS are going 
to look for some method in the FileObject (or if they're clever in the 
FileContentInfo).  Either of these places are logical places to look for 
metadata methods.

Any ideas about how we could make it easier for them?
