Outside the core: working towards an industry recommended practice for supplemental journal materials

Increasingly, authors are submitting additional content along with their papers for publication. These supplemental materials can range in type from supporting narratives to datasets, to visualizations and executable programs. There is no consensus about how best to handle these materials: whether they should be reviewed, edited and marked‐up by publishers; how to cite them; or how to preserve them. In partnership with the National Federation of Advanced Information Services (NFAIS), the National Information Standards Organization (NISO) has launched a project to develop a consensus‐based recommended practice on how best to incorporate supplemental journal materials into the publication stream.
