13. Questions: 1. Which project work flows and tools are successful in helping to find, integrate, and manage data?; and, 2. What are specific questions or challenges facing the project with respect to accessing, integrating, or managing data? Data Privacy (Can’t share response with public, other researchers) Could not do this if we started today? Real-time sharing of data with partners. Geocoding/geolocation. Google-based, but this is a moving target. Tools: LAMP, XML data exchange, Level3-cache, multiple isolated servers Publicity: Mother Nature
