Even though there are still difficulties in addressing this topic due to legal and technological control restrictions,
the truth is that the improvements are aimed at enabling access, starting with open policies. Bearing in mind that
there are standardization issues for re-use that are more demanding and broader than the public access ones, open
access models imply the use of documents under a Creative Commons license or a similar agreement that permits
a more liberal use (including redistribution) than the traditional principles of fair usage.
