Error 2

E2: If range specified, no explicit value specified (for quantitative properties and for currencyValue)

Validator Tool: Step # 2

Error Message

A specifec value (hasValue) cannot be defined when a range is present (hasMinValue or hasMaxValue) for both numeric and currencies values.

Potential Problem

Prices and quantitative product properties can be specified as intervals using the gr:hasMinValueFloat - gr:hasMaxValueFloat, gr:hasMinValueInteger - gr:hasMaxValueInteger and gr:hasMinCurrencyValue - gr:hasMaxCurrencyValue properties. Care must be taken that if a range is present, no specif value should be included (hasFloatValue, hasIntegerValue, and hasCurrencyValue.

Examples of Wrong Data

Wrong Data: hasMinValueInteger, hasMaxValueInteger, hasValueInteger
