DDI 3 Comparison test-case
{"Image DocumentName": "DDI 3 Comparison test-case", "Image ImageDescription": "Use of Comparison Module: Questions/Comments. We normally include items (i.e., variables in our case) that have some degree of comparability. None would not be routinely used. Use of CommonalityWeight is optional: a scale of weights would have to be defined. UserDefinedCorrespondenceProperty may replace CommonalityTypeCoded in user-specific cases. Map structure identical (except for codes) but items compared are organically different : not all elements are relevant in all maps. (For variables we find it necessary to list similar and different components of their description, but for universes, or questions, etc., comparison would be at a more conceptual level)", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
