I answered in OpenMRS Talk too
Sara,
Generally I feel that terminology is not an easy thing for most people to do without \
additional training and that is why I created the CIEL dictionary to help people. It \
is MUCH easier to find an interface terminology which is the same thing as the term \
you are mapping (SAME-AS) and then rely on someone else's maps to get to the \
reference terminology (SNOMED, etc.). In your example, it sounds like you are trying \
to map to a categorical terminology like ICD. You could map it NARROWER-THAN to ALL \
of those. Fungal skin infection would be the closest but none of them are SAME-AS. \
However, if you are ICD coding, then there are special rules which dictate which ICD \
code should be used for a given term, and those might not be totally obvious from the \
term and the categories. In general you should only map to the closest map and not \
any that are in the same hierarchy (so Fungal infection is a parent of fungal skin \
infection and would be redundant). There are other mapping relationship types which \
might be added. You should probably not have two SAME-AS maps within the same mapped \
terminology. Happy to provide more detail if needed.
