The trick is finding a problem that increases revenue or decreases costs after providing structure to the data. Sure, it would be great to bring structure to assets, but you can't just provide search or labeling. You have to figure out how providing the structure actually brings value to those companies. You'd hope they would do that for you, but you need to figure it all out, at least for one set of customers who will pay you, before you build the MVP. The details of how it benefits the company has a profound effect on the design of the MVP, including how to access the assets and how to expose the structure in the UX.
