Quality Indicator 5: Size of collection items

Many collection items have information about their width iisg:widthInCm and their height iisg:heightInCm readily available in their properties. While most images do have their values inserted some miss either the height or the width of the image while this is available in the property iisg:size. As shown in Table 1 below, these items miss either their iisg:heigthInCm or their iisg:widthInCm while the iisg:size is always known.
