Biotechnology — Data publication — Preliminary considerations and concepts
This document reviews best practices that:
a) respect the existing standardization efforts of life sciences research communities;
b) normalize key aspects of data description particularly at the level of the biology being studied (and shared) across the life sciences communities;
c) ensure that data are “findable” and useable by other researchers; and
d) provide guidance and metrics for assessing…
