The Grasslands Data Integration (GDI) project has brought together ecologists, information managers and computer scientists to address the interdisciplinary challenges of integrating ANPP data from multiple sources. In this poster we present 1) the necessity to coordinate expertise and information to integrate ANPP data and metadata from five national and international grassland LTER sites, 2) the data model we designed to archive and serve the data, and 3) analysis planned for the future. This collaboration is an example of how professionals with inter-related work experience build a community of experts and a successful data product for the LTER (Baker and Millerand 2007).
