As part of the Fresh Look initiative HL7 went into a bit of self reflection, partly
because of the low uptake of HL7 version 3 messaging: what would a good (and: new)
specification look like? RFH is certainly a prime candidate.
See healthintersections.com.au/rfh/introduction.htm for the specification, and healthintersections.com.au/?p=502
for the associated blogpost which announced it.
