 Okay, so this is an introduction to PROV that I'll be talking about. PROV is a W3C, that's the World Wide Web Consortium-issued recommendation, which means it's a standard, and I'll be mentioning a little bit about the history of that standard and how it's composed, the parts to the standard, what it can do for you. Then I'll talk very briefly about how you do some modeling according to PROV, then how you can manage data once recorded in PROV, and then how you actually use PROV with other systems such as other domain-specific metadata initiatives.
