Hi.
We have been curating a list of Brazilian open data catalogs in this Github repo. I’ve noticed many of those are not yet in the dataportals.org dataset (and not even in Datasoft’s 1600+ list of data portals) and maybe it could be merged into it.
I’d do a PR myself when I have some time, but if anyone wants to get ahead and do it, you’re welcome to.
Best regards,
Augusto Herrmann
