I'm working on a UI problem when it comes to map data. Imagine you have a wall (object) that contains multiple layers like insulation, concrete and plaster (childs). To provide value with the software user needs to link additional data to objects. User needs to be able to map one data set directly to an object or map the object by mapping one data set to each child. Means one object could be either mapped as itself or by his childs. The data sets define which way of mapping makes more sense. In addition its not given that we have childs for all objects. Another requirement is that user is likely to pre group objects by different attributes. Each group can contain multiple objects with different constellations of childs. How would you layout/wireframe a UI for this job if amount of objects could be more then 1000 objects?
Let me know if I can help with more information :)
