6.PICK & ATTACH A LICENSE

FACTS:- Linked Data with a non-open license is nonsense- EU Commission mandates Open Access in research projects- Most Italian universities signed the Berlin Declaration for Open Access (4 exceptions)- No license automatically means = All rights reserved (like a book you cannot quote!!!)- License for Data may be different from License for Metadata
