Hi, First many thanks for the explanation of the different entitities in the Steam Asset API. It was very confusing to me before reading your post. Now, at least, I'm able to ask a question :-). This one is about the Asset Classes. Do have any thoughts about how an Inventory provider should handle these classes when mapping a number of them to a single description returned in the GetAssetClassInfo response? To me it feels like constructing an apple from a pear. How can one interpret an AssetClass? Is an Asset aggregated by a number of AssetClasses? It also seems strange that these classes are cached in Steam. What information is cached then? Only their ids? Because the Steam Asset API don't let Steam know anything about an individual Asset Class information despite the GetAssetClassInfo request (since it only returns the overall Asset information). Maybe I completely missunderstood this?! Best regards, Einar
