I’m not sure. That question would be best posed to the folks at the National Library of Medicine (UMLS support page: https://www.nlm.nih.gov/research/umls/support.html).

could the difference be due to the transformation from the ATC original format to the UMLS format?

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?
Yes, that’s correct.
The original WHO ATC, as available at  does not have the classes “Ergot alkaloid oxytocics” and “Porstaglandins, Oxytocics”
while the one in bioportal does have these two classes , .
You are seeing those classes because they are present in the UMLS distribution of ATC that we imported into BioPortal (UMLS version 2016AA). I’ve included a couple of screenshots below from the UMLS Metathesaurus Browser where you can execute searches restricted by source ontology and release version.
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) .
The version of ATC contained in the UMLS has 17 root classes - that’s why you see the same in BioPortal (another screenshot below of the ATC hierarchy from the UMLS Browser). We don’t modify the contents of the ontology when we do the import.
I’m assuming the website you mention below (https://www.whocc.no/atc_ddd_index/) offers the most current version of ATC (although I didn’t see a version number anywhere)? If you’re seeing differences between the canonical distribution from the WHO and BioPortal content, it’s likely because BioPortal has an older version. According to UMLS documentation, ATC is only updated in their system once annually:
thanks in advance,
