Topic: R2 to R3 Mapping Statements
Grahame Grieve (Nov 27 2016 at 19:07):
At DevDays, several people asked me about using the FHIR Mapping language to translate between FHIR R2 and FHIR R3.
Where we are with this is that I maintain a hand-written java clas that can interconvert between R2 and R3. The Build tooling makes extensive use of this for the conformance resources
Grahame Grieve (Nov 27 2016 at 19:08):
what I've written is a new java class that parses that java class and converts the code to a set of mapping statements. I've committed the class and it's output to svn - see \build\implementations\r2maps for the output
Grahame Grieve (Nov 27 2016 at 19:09):
my intention is to build this into the specification for the early Dec milestone, though they will need significant amounts of quality work
Grahame Grieve (Nov 27 2016 at 19:10):
so far, I only have data type maps, for R2 to R3

What do the "% RoundTrip Ok" and "% R3 Valid" columns actually mean at http://build.fhir.org/r2maps.html?
Vadim Peretokin (Feb 14 2017 at 19:36):
Is the first how many resources got roundtripped ok, or is it % of a resource that was roundtripped ok? Not sure what the valid part really means either
Grahame Grieve (Feb 14 2017 at 19:42):
% Execute ok is the % of resources where running the script doesn't terminate with an error
% Round trip ok is % of resources where running the script r2 -> r3 and r3 -> r2 results in the same canonical resource
% R3 valid is the % of resources where the R3 resource passes validation

Got it, thanks!
Grahame Grieve (Feb 14 2017 at 19:44):
the scripts are not being maintained since mid-jan. I'll do a round of editing on them once substantiative changes cease
Brian Postlethwaite (Feb 16 2017 at 05:28):
the r2 diff stuff in the ini, we can correct that post this sunday right?
Brian Postlethwaite (Feb 16 2017 at 05:30):
Is there a way to provide a mapping across resources? (1 resource in DSTU2 = 2 resources in STU3)
Grahame Grieve (Feb 16 2017 at 07:32):
yes the scripts work for that already .
Grahame Grieve (Feb 16 2017 at 07:32):
and yes, this can be correct post sunday night
