At DCMI meetings in Manzanillo, a new structure for technical work has been discussed and approved. DCMI Working Groups will be restructured as DCMI Communities and DCMI Task Groups. A DCMI Community, with a Web page and mailing list, will serve as a forum for open discussion on special topics or domain applications. A DCMI Task Group will develop specific deliverables such as application profiles on a DCMI wiki. In addition to existing groups, a new community is forming around the topic of social tagging. Further announcements will be made on the DCMI Web site and in DCMI mailing lists over the coming months.
