LTER Data ManagementSites are the experts for their own data, and should work with the systems and partnerships that are availableSites collaborate as appropriate within the LTER to develop the software they need, and create economy of scale by converging practices and mechanisms Network sets goals and provides a collaborative atmosphere, but does not dictate mechanisms Cross-site comparisons began in the 1990s Developed XML-based data sharing mechanismEML released in 2003
