      abstract     = {The utilisation of metadata repositories increasingly
                      promotes secondary use of routinely collected data. However,
                      this has not yet solved the problem of data exchange across
                      organisational boundaries. The local description of a
                      metadata set must also be exchangeable for flawless data
                      exchange. In previous work, a metadata exchange language
                      QL4MDR was developed. This work aimed to examine the
                      applicability of this exchange language. For this purpose,
                      existing MDR implementations were identified and
                      systematically inspected and roughly divided into two
                      categories to distinguish between data integration and query
                      integration. It has been shown that all the implementations
                      can be adapted to QL4MDR. The integration of metadata is an
                      important first step; it enables the exchange of
                      information, which is so urgently needed for the further
                      processing of instance data, from the metadata mappings to
                      the transformation rules.},
