The "data dictionary" for RMAN is in (a) V$ views from the controlfile and, if a Catalog Schema is implemented (b) Catalog Views.
A useful mapping of the two sets is
(for 11.2) at http://docs.oracle.com/cd/E11882_01/backup.112/e10643/rcviews001.htm#RCMRF1923
(for 12.1)
at http://docs.oracle.com/database/121/RCMRF/rcviews.htm#i77529
Sometimes (many a times ?) it is better to use these views than the RMAN LIST / REPORT commands. But it might be a tad difficult to understand these views and write the appropriate queries.
So, we extract a list of RMAN Backup Jobs. This V$ view listing spans Instance restarts !
Note, however, the INPUT_TYPE reported is based on the backup command. For example, the 06-Sep backup command was a single "backup as compressed backupset database plus archivelog;" which actually created multiple BackupSets for ArchiveLogs, Database Files, ArchiveLog and Controlfile. All of them appear together as one entry "DB FULL". See my earlier posting "RMAN -- 1 : Backup Job Details" for another example of how you might misinterpret this view.
If it is single command, even the SUBJOB details view doesn't seem to be helpful.
So, be careful when trying to interpret the results of a query on this view if you don't know how the backups are run.
This, below, is the query on the corresponding Recovery Catalog view :
(Remember the first 10-Aug backup doesn't show because it was before a RESETLOGS and the Recovery Catalog doesn't show backups prior a RESETLOGS that was issued befor the first Full Resync into the Recovery Catalog. See my previous post).
What about listing individual datafiles ?
(Note once again, the backup before the RESETLOGS isn't included when querying the Recovery Catalog simply because the RESETLOGS was before the Full Resync).
And Backup Sets ?
Note that the RC_BACKUP_SET view shows the type of controlfile backup (whether a BACKUP or a STANDBY) not whether it is included in the BackupSet. SET_STAMP and SET_COUNT are the Join to V$BACKUP_DATAFILE. I use the Join to show the backup executed earlier today :
So, for the BackupSet 310, I have datafiles 1 to 11 backed up between 21:25 and 21:33 today. Set 312 has a Controlfile (Auto)Backup. You may notice some slight differences in the query the RC_% views versus the V$ views.
What about BackupPieces ?
BackupSets 309 and 311 contain ArchiveLog backups while 312 contains the Controlfile (auto)backup.
In the earlier scripts joining V$BACKUP_SET with V$BACKUP_DATAFILE, I've already identified datafiles in each BackupSet (in this case only 1 BackupSet for datafiles today). You could have your multiple datafiles spread across multiple BackupSets.
Question 1 : Can you map Datafiles to BackupPieces ? Answer : No. Follow-up Question : Why note ?
Question 2 : Can you write a script mapping individual ArchiveLogs with BackupSets ? Please submit your scripts (a minimal listing of columns suffices).

BackupSets 309 and 311 contain ArchiveLog backups while 312 contains the Controlfile (auto)backup.
In the earlier scripts joining V$BACKUP_SET with V$BACKUP_DATAFILE, I've already identified datafiles in each BackupSet (in this case only 1 BackupSet for datafiles today). You could have your multiple datafiles spread across multiple BackupSets.
Question 1 : Can you map Datafiles to BackupPieces ? Answer : No. Follow-up Question : Why note ?
Question 2 : Can you write a script mapping individual ArchiveLogs with BackupSets ? Please submit your scripts (a minimal listing of columns suffices).
