Depends on what you want to use.
I usually use the shell and the stat command:
$ stat tgif-rpms.tar
Size: 4126720 Blocks: 8080 IO Block: 4096 regular file
Device: 821h/2081d Inode: 15237152 Links: 1
Access: (0664/-rw-rw-r--) Uid: ( 500/ jesse) Gid: ( 503/ family)
Access: 2011-04-01 18:19:04.048817920 -0400

Change: 2010-09-08 10:53:29.764610959 -0400
Now this still doesn't list the SELinux label associated, but that is not what the metadata is about. For that I usually use "ls":
$ ls -Z tgif-rpms.tar
-rw-rw-r--. jesse family unconfined_u:object_r:user_home_t:s0 tgif-rpms.tar
Now "ls" can provide most of the information in the stat output, but not all at the same time (different options substitute values in the same column):
$ ls -l tgif-rpms.tar
-rw-rw-r--. 1 jesse family 4126720 Aug 22 2010 tgif-rpms.tar
Nautilus has a view menu that can select a list format that reflects
what "ls -l" does with more information and in a more verbose manner.
Nautilus also has a <alt><return> (properties display) capability to list most of the metadata.
