The members of the Darwin Core Maintenance Group are happy to announce the opening of a minimum 30-day period for public review for a set of proposed changes to Darwin Core coming out of research and discussions in the Material Sample Task Group, ably led by Teresa Mayfield-Meyer over the past two years.

Please refer to the documentation we have provided on the review process and the maintenance of the Darwin Core standard in general at https://github.com/tdwg/dwc/wiki/Darwin-Core-Maintenance-Frequently-Asked-Questions.

For your reference and convenience we are providing a table with links to the proposed changes, organized in keeping with the order in the Darwin Core Quick Reference Guide (https://dwc.tdwg.org/terms/). The relevant issues are also listed in the following milestone: https://github.com/tdwg/dwc/milestone/18.

Your comments are welcome and important for the evolution of the Darwin Core standard.

Thank you,

The Darwin Core Material Sample Task Group
The Darwin Core Maintenance Team
