I saw this "Further, this ID value must be numeric; it is a Java long type through the APIs" in the taste documation. But in the javadoc of FileDataModel,there is "The user and item IDs are ready literally as Strings and treated as such in the API" Does it mean that userID and ItemID could be string now, for example, my data is look like this: "Auser,apple,1 User2,banana,2 User3,car,3" Could I use FileDataModel directly? Thanks
