Transformation of Metadata Descriptions

Transformation is the process of creating a target instance of the metadata description from the source instance. The transformation uses semantic mapping and rules to create the target instance.

It is important to note that the result of the transformation is a metadata description. The created description is sometimes referred to as a crosswalk, but this is an inappropriate usage of the word. See the Crosswalk guide for more information about the distinction.

Rules for Complex Metadata Mappings

The introduction and definition of rules is an essential step for most cases of creating semantic mapping between standards because of complex relationships that often exist.

To deal with complex mappings (when the mapping from source element to target element is more complex than one-to-one) between standards, we require the introduction of rules.
