[bioontology-support] [BioPortal] Feedback from naveen.ponnuswamy

Hello Naveenkumar,

We're sorry, but there is no way to download the MedDRA dictionary from BioPortal, due to its licensing restrictions.

It is possible to download all of the classes by using the BioPortal API and iterating through the pages. The API documentation is at, for example (but including your API key as described at the top of the Common Parameters table).

Hello Team,

Can you please guide me on how to download the complete MedDRA dictionary along with / without ontology in any of the RDF serialization formats.

Best regards
