- The main discussion forum for Dublin Core is a mailing list called dc–general.
- In order to minimise discussion on this list, most of the work associated with moving Dublin Core forward has been devolved to a series of working groups. Some of these groups deal with issues specific to one or more Dublin Core elements, whilst others address more generic topics
- All of these lists are open for anyone to join, and they are the Dublin Core
- All previous DC lists no longer used.
