These fields always appear in their own, discrete record, and none of them is repeatable.
The dynasty records are a little more elaborate than the siku authority records, as there is more to define. The two-digit code is enterered into #7Sc, the name of the dynasty into #7Sd, and the dates into #7Se.
The name of the succeeding dynasty goes into #7Sf, and any notes into #7Sn, although this last field has not been used to date (22 April 2016).
#7Sc 15
#7Sd 秦
#7Se 221-206 B.C.
#7Sf 漢
#7Sc 27
#7Sd 晉 -- 五朝十六國 -- 前涼
#7Se 301-376
#7Sf 前秦
To keep the entries for these dynasty authority records apart in the index, the program prefixes them with a plus sign:
