Hi, 1. I already used similar product template for experimenting. https://predictionio.incubator.apache.org/templates/similarproduct/quickstart/
For UR, are the data queries for the eventserver about the same, but can take more properties? In my case three events. Set users, set items and set buys. 2. I have coordinates for the users. Is this supported as property? Note: in my case I like to make predictions by user id and by an array of item ids which is supported, also for products that are never bought for cold start. I have item properties like category id, manufacturer id, label and price range. Thanks in advance
