Generating OWL for the LOINC/SNOMED Ontology

[riannella]

I downloaded the SNOMED release that includes the LOINC terms (as subclasses of Observable entity) from here:
https://loincsnomed.org

When I convert this release to OWL, it does not include the identification of the original LOINC Term in the output owl file.
The SNOMED browser includes this:

Any ideas how I can get this info (owl:equivalentClass?) via the conversion process?

These seem to be added:

It's true that the RF2 to OWL conversion process does not currently take the LOINC "alternate identifiers" from the RF2 files into the OWL ontology file.
I have raised the question with the relevant group in the comments section here: https://confluence.ihtsdotools.org/display/mag/SNOMED+International+Proposal+to+change+the+RF2+Identifier+File+specification

@riannella
A method to add this information has been suggested in the comment here: https://confluence.ihtsdotools.org/display/mag/SNOMED+International+Proposal+to+change+the+RF2+Identifier+File+specification?focusedCommentId=221184314#comment-221184314
I like the look of option 2. That could be added to the RF2 to OWL conversion tool fairly easily.
