4.9 FRM / PLF / SRC

4.9.1 FRM  (Origin)
Definition:  Frm defines an origin of a thing

Example 1

English

A letter from him

UNL

frm ( letter.@entry, he )

Example 2

English

This idea is from him

UNL

frm( idea, he.@entry )
mod ( idea, this )

Comments on Example 1 & 2

The difference between "This idea is from him" and "an idea from him" is, in the prior sentence the UW of "him" is the main UW but in the last one "idea" is. (see 3.2 for more explanation on @entry)

4.9.2 PLF  (Initial place)
Definition:  Plf defines the place an event begins or a state becomes true

Example

English

Participants come from the whole world

UNL

agt ( come.@entry, participant.@pl )
plf ( come.@entry, world )
mod ( world, whole )


4.9.3 SRC  (Source : initial state)
Definition:  Src defines the initial state of object or the thing initially associated with object of an event

For relation “src”, there is always a point of reference of object "obj". Sometimes, the object is overlapped to agent "agt".

Example

English

The traffic light changed from red to green

UNL

obj ( change.@entry.@past, light )
mod ( light, traffic )
src ( change.@entry.@past, red )
gol ( change.@entry.@past, green )
