From a SciELO Blog Post:
The SciELO Program has updated the document “Criteria, policy and procedures for the admission and permanence of journals in the SciELO Brazil Collection” with a new version that takes effect from May 2020. The document is referred to as SciELO Brazil Criteria for its purpose and function of contributing to the development of Brazil’s journals, and at the same time, it serves as a reference for the indexing criteria of all SciELO Network collections.
The adjustment of policies and editorial management in the perspective of the progressive adoption of open science is the main action that indexed journals must carry out to comply with the new criteria. The practices that will be required from SciELO journals refer, first, to accepting submission of manuscripts-preprints, i.e., that are posted in a preprint server; second, citing and referencing all data, software codes and other content underlying the articles texts in order to facilitate research evaluation and replicability, and preservation and reuse of content; and third, options for opening peer review. This adjustment is expected to occur by the end of 2020 for journals already indexed.
