Would you be willing to add those references to https://meta.wikimedia.org/wiki/Abstract_Wikipedia/Related_a... (creating a new section for UMR) and perhaps https://meta.wikimedia.org/wiki/Abstract_Wikipedia/Related_a... if you're aware of any references that talk about "creating complex, non-trivial text starting from an abstract meaning representation"? That would be the best way of making this discussion useful for what Wikipedia is apparently trying to do.
