I guess the basic idea is to represent a (upper) triangular matrix

A B C
0 D E
0 0 F

as a rectangular matrix

A B C
F D E

The same idea can also be exploited to represent symmetric and Hermitian matrices. The are some different cases and details to consider, so there might exist some different formats with the same basic idea. The link should explain the RFP format.
