In all these categories, the meaning and usage of the properties is identical:
The
source
property identifies existing data holders that a transformation should use.
The
target
property identifies data holders that may or may not already exist. If they exist, the transformation uses them. If they do not exist, the transformation creates them.
After you define the
source
and/or the
target
, the subsequent components use the identified data holders. For example, if you define the
target
of a
Group
, the anchors nested within the
Group
use the data holders that the
target
identifies.
There are properties called
source
and
target
in some other components such as
Map
. These properties have a different meaning and usage from the above. For an explanation, please see the components where the properties are used.
