Beth Plale has published "Synthesis of Working Group and Interest Group Activity One Year into the Research Data Alliance" in D-Lib Magazine.
Here's an excerpt:
The Research Data Alliance (RDA) uses Working Groups and Interest Groups to carry out its work. Groups form when a concerned community develops around a topic for which there are well defined issues, common goals, and an opportunity to create a framework for timely action. One year in, RDA has 26 Working Groups and Interest Groups whose activities are focused on overcoming barriers to successful research data sharing, publishing, referencing and archiving, and on developing the infrastructure necessary to support those tasks.
