Although the importance of introducing instruments that allow access is manifest, legal limitations that hinder
these initiatives are ever present, such as intellectual property. In the case of industrial property, there are private
companies that own patents and can restrict access to their content for a specified time (Landes & Posner, 2003);
also, in the case of copyright, there are requirements for anyone wanting to access and share information. These
include obtaining the owner’s approval and providing full author identification to acknowledge the work, and in
some cases paying fees or licenses to access it (Plata López, 2010). This indicates that the vast majority of resources
that are digitally accessed are subject to rights and ownership, and therefore tools that respect and balance the
interests of both creators and knowledge promotion must be introduced.
