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.
The public review discussion is happening here: https://github.com/tdwg/dwc/milestone/18. You may find context for the proposal and discussion in the New Term - dwc:MaterialEntity (the last proposal in milestone 18).
Please also 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 provide a table (below) with links to the proposed changes listed in milestone 18, organized in keeping with the order in the Darwin Core Quick Reference Guide.
We welcome your comments. Your participation is important for the evolution of the Darwin Core standard.
Thank you,
The Darwin Core Material Sample Task Group
The Darwin Core Maintenance Team
