This translation clarified the precise relationship between these two related formalisms, and made the powerful meta-theory of dominance constraints accessible to MRS. Their goal was to also make the large grammars for MRS and the efficient constraint solvers for dominance constraints available to the other formalism.
niehren and Thater made three technical assumptions: 1. that EP-conjunction can be resolved in a preprocessing step; 2. that the qeq relation in MRS is simply dominance; 3. and (most importantly) that all linguistically correct and relevant MRS expressions belong to a certain class of constraints called nets.
