In the concept of a service mapping an input to an output, the sswap:Object corresponds to the output. The property sswap:mapsTo explicitly demarcates the mapping (or transformation) from an input to this output. One can also use sswap:mapsTo to describe inverse mappings where the stated relationship is from a sswap:Object to a sswap:Subject.

        Required predicates: (none);

        Optional predicates: sswap:mapsTo.</rdfs:comment>
