Open Access and Copyright Policy

Open Access Policy

Since its inception in 2025, CDEJ has adopted an open access policy based on the principle that making research freely available to the public supports a broader global exchange of knowledge and produces beneficial results for humanity.

CDEJ is an open access journal that makes all its content freely available to users worldwide, without requiring any permission from the publisher or author(s). Users can read, download, distribute, print, and link to articles citing the journal without asking for permission. This unrestricted access encourages wider dissemination of research and ensures greater academic impact.

This policy complies with the open access definition of the Budapest Open Access Initiative (BOAI). CDEJ is a signatory to BOAI.
