[bioontology-support] ATC / bioportal

Thanks Jennifer.

If I understand correctly you do not take care of converting (transforming)
the original WHO ATC vocabulary into an RDF file. Instead, you just take
whatever UMLS has and that is what you transform to RDF. Right?

The original WHO ATC, as available at [1]  does not have the classes “Ergot
alkaloid oxytocics” and “Porstaglandins, Oxytocics”

while the one in bioportal does have these two classes [2], [3].

I would like to know what other differences in the hierarchy are there
between the original WHO ATC (14 main groups) and that in bioportal (17
main groups) [4].

thanks in advance,
