@vermaden EUPL is a copyleft license, while BSD a permissive one. So they are very different.
EUPL is similar to a merge between LGPLv3+ and Affero GPL: like in Affero, if you use an EUPL library in a cloud service, you had to release improvements to the EUPL library under EUPL; but like in LGPL, you can maintain your product code propietary.
It is a rather clear license to read (simpler than the GPL), except the the differences between derivative-work and distinct product.
I'm writing this, because up to date EUPL is may favorite license :-)
