Ordo notation.
Singleton moves are notated as suspected, i.e. origin space coordinate, followed by "-", then the destination space coordinate is given. Capture moves are marked with "×" instead.
b2-d4, e2×e5
Ordo moves are notated as follows: Firstly the coordinate of the first piece from any edge of the moving ordo is given, followed by ":", then the coordinate of the last piece in that ordo, then "-" and finally the destination space of the firstly chosen piece. Thus there are always two possible notations for an ordo move.
f5:i5-f2 (or i5:f5-i2)
