JATS4R

JATS4R (JATS for Reuse) is a working group devoted to optimizing the reusability of scholarly content by developing best-practice recommendations for tagging content in JATS XML.

As of December 2018, JATS4R is working under the auspices of NISO.  The JATS4R website describes the initiative, lists all the recommendations, and details how you can get involved.
