Group Mapping Rules

Group mapping rules specify the construction of xfMap groups, and they must be defined inside the <group-map> or <group-content-map> elements.

FME features that are created through the feature mapping rules may be further processed by the xfMap groups, these are processing entities that reside inside the XML Reader in which features may enter and leave, but while inside a group, the features may be further modified through:

1. the attachment of group specific attributes, and/or
2. the processing of an FME factory pipeline.

All group mapping rules whether they’re defined under the <group-map> or the <group-content-map> elements have the same structure.

Unlike the feature mapping rules every group mapping rule when activated, regardless of where it is defined, triggers the XML Reader to construct a new group.
