Here's an excerpt from the announcement:
The primer on Research Data Management provides an overview of how data management has changed in recent years, and outlines best practices for the collection, documentation, and preservation of research data. The importance of creating a data management plan (DMP) before beginning a research data project is emphasized. Crucial questions regarding how the data will be managed are answered ahead of time in a DMP, thus making it easier for the researcher to collect and document the data properly for future use and reuse. Creating research data that is easily reproducible and transparent is the ultimate goal, and following the guidelines in this primer can help educate researchers to ensure their data is available for others. The differences between publishing papers and publishing datasets and the citation challenges the data community are working on solving are also discussed.
