For centuries, libraries, archives, and museums have been creating structured data, organizing information, and managing metadata in order to organize and share cultural artifacts and knowledge with the public. Unfortunately, the bulk of these systems have evolved in isolation, long before the advent of the World Wide Web. However, the convergence of developments in culture and technology are resulting in exciting new ways for individuals and developers alike to interact directly with unprecedented amounts of structured data, historical photos and archives, and more. Expert developers and project managers in this field will lead a discussion focused on the question: How can developers leverage open data from libraries, archives and museums being made available to the public? Panelists will review new developments and highlight examples, considering use cases with Linked Data, Flickr Commons, Smithsonian Commons, mobile apps, and scalability.
