Penman now has edge and attribute reification, ported from Norman, but not the reverse process. Edge contraction (also called "collapsing" or "dereification" in Norman) would be more useful for DMRS than AMR since DMRS tends to have "reified" nodes by default (in a sense), whereas AMR almost never reifies relations unless necessary.

Renamed to "dereification" because "contraction" has a slightly different meaning in graph theory, even if topologically the result is the same (if we don't consider the instance triple an edge). Reification entails the creation of a new node with a particular label, so dereification is the reversed process, resulting in an edge with a particular label.
