  While there exist approaches to integrate heterogeneous data using semantic
models, such semantic models can typically not be used by existing software
tools. Many software tools - especially in engineering - only have options to
import and export data in more established data interchange formats such as XML
or JSON. Thus, if an information which is included in a semantic model needs to
be used in a such a software tool, automatic approaches for mapping semantic
information into an interchange format are needed. We aim to develop a generic
mapping approach that allows users to create transformations of semantic
information into a data interchange format with an arbitrary structure which
can be defined by a user. This mapping approach is currently being elaborated.
In this contribution, we report our initial steps targeted to transformations
from RDF into XML. At first, a mapping language is introduced which allows to
define automated mappings from ontologies to XML. Furthermore, a mapping
algorithm capable of executing mappings defined in this language is presented.
An evaluation is done with a use case in which engineering information needs to
be used in a 3D modeling tool.
