The journal is multidisciplinary and international in scope, offering a home for research papers across the “Sciences”, “Technology”, “Engineering” and “Medical” domains. Underlying these aims are the four key principles of Open Science: Open Data - 4open authors are invited to upload supplemental datasets related to their research to an online repository, making it available for both human and machine reading in order to further aid the acceleration of scientific discovery. Open Code – authors are invited to make this publicly available in order to make the research methodology explicit and allow for the replication of processes in subsequent exploratory research. Open Papers - in order for research advances to achieve optimal reach and impact, 4open publishes in fully Open Access with no embargo period. Open Peer Review is encouraged by the journal, dependent on both the author and the reviewer’s agreement to this format. 4open believes that open peer review provides a holistic view of a published piece of work, allowing for more thorough critical evaluation.
