iWay Transformer Mappings

In this section:

Mapping Rules
Mapping Structure

Mappings consist of rules that define how a transformation is performed for a project, based on an input and output configuration. They are managed using Mapping Builder.

Mapping Rules

Mapping rules define a set of requirements performed in the course of a transformation, based on particular input and output configurations. A mapping rule specifies how records and fields of an output document structure are calculated in relation to the input structure. Each mapping rule:

Points to a single node of an output structure.
Contains a formula for obtaining data for a value of an output node.
Can map one or more of the input structure items to an output structure item, depending on the type of the mapping value used.

The following diagram shows the mapping rule process.

Mapping Structure

A mapping structure represents a structure (layout) of a document. It consists of interconnected nodes. Each mapping node has:

A mapping type. For more information, see Mapping Types.
A mapping value. For more information, see Mapping Values.
A specific place in the structure that defines its mapping relationships.
