Hi Woodley,

Thanks for getting in touch.  Insofar as I envision using MRS as a
resource, it would be plain text in single sentences or well-formed
sentence fragments.  The pipeline we're developing is still malleable
though, so it would be fairly simple to change formats or insert a
preprocessing step depending on the tools or resources already available
that we might want to make use of.
