One person's metadata is another's data! You (may be unintentionally) characterise it as a market where you check boxes on "datasets" to buy, but it's far from that. Monetizing by licensing/selling some kind of log data isn't really interesting--but understanding what signal can be derived and how it can be applied to an opportunity (arbitrage, value added analysis, financial product/insurance etc.... is where it gets interesting.

I've written a bit about derivative uses of data if you are interested: https://post-employment.com/category/business/
