Dimensions are identified by a `name`, and can be derived from a `dimensionExpression`. These expressions include: `lowerCase` or `upperCase` that are used to adjust the case of a dimension value. The expression `concatenate` combines multiple dimension values into one, using a specified `delimiter`. These dimensions in requests can use multiple fields and refer back to the dimensions' field.\n"]]
