I've done that in a datawarehouse system.
The fact tables were partitionned by date.
Some fact tables were keeping different number of
months : 6o, 12, 15,...
This was handle in the metadata tables and was written
with PL/SQL (Oracle 8). You can do a lot of things
with PS/SQL.
So the metadata was containg the table name, the
naming convention of the partition, the naming
convention for the tablespace, disks name, the number
of partition per table, ...
Data was moved into retention data tables then the
partition were rolling : creation of new tablespaces,
creation of new partition, moving data to the
retention tables, dropping partition,...
