Colombia *Correspondence: editormvzcordoba@correo.unicordoba.edu.co Since the appearance of the internet, the way of disseminating information has been changing, moving from printed publication to digital publication, giving rise to innovative ways of disseminating new knowledge. These innovations have also brought with them changes in the way of accessing this knowledge, going from paying for its access to having it at no cost. In recent years there has been talk of open access to information and as a result many defnitions, characteristics and use of this term have appeared according to the frst Open Access (OA) initiative in Budapest in 2001. For example, “open access” we mean its free availability on the public internet, allowing any user to read, download, copy, distribute, print, search or use it for any legal purpose, without any fnancial, legal, or technical barriers, other than those that are inseparable of those implied by accessing the internet itself” (1,2). Within the spectrum of OA, there are several models used today where you can fnd OA publications after payment of APC (article processing charge in English), this cost is assumed entirely by the authors; hybrid publications, in which open access is given by subscription and where the author has paid for it to be so, is very common in large publishers; OA publications by embargo, these are given some time after publication (the embargo is usually one year); free publications, where the authors do not assume any cost of APC, which is generally assumed by the public organizations that fnance the publications (2,3). Although when referring to the term OA it could be interpreted that what is published can be freely used, this is not really the case, since the fundamental pillar of this initiative is that the authors preserve their moral rights (these are inalienable and consist of the right to be recognized as authors of their works and is non-transferable to a third party) intact and economic rights (they are the rights that the author assigns to a publisher or publisher so that his work can be reproduced, distributed, transformed and communicated publicly) and can be maintained by the publishing entity (4.5). As described above, there appears a legal model created by an American non-proft corporation that is inspired by the General Public License (GPL) of the Free Software Foundation “Creative Commons”,
