"I have a pitch meeting in a week. Can you build me a website that has all the articles, video, images related to my last three grants?"
What are the data use cases we may encounter?
"Discovery Channel called, they want all the video we have on whale activity near Georges Bank where Michael Moore's whale monitoring instrumentation was used."
