Open access journals are accepted to the rating and are evaluated on the same criteria as traditional publication series. For the levels 2 and 3, the aim is to promote the open science in the following way: Green OA channel can be favored if the embargo is at most 6 months in natural sciences and engineering, and 12 months in SSH. Also open data can be taken into account.”
• if candidates to the level 2 or 3 in the same field have equal impact or prestige, open access journal or the one permitting self-archiving of the peer-reviewed version of the manuscript is chosen to the higher level over the channel that does not support open access.
• the channel allowing for self-archiving can be favoured in comparison if the embargo period is in science and technology for six months and in human sciences for 12 months.
• openness of data can also be considered an advantage. It is checked in the case of comparison whether open access provides grounds to decide selection.
