I agree with Rob on this one, No and for the same reasons. I don't think that the multi class examples are a good idea. I think it gets into the business of how to model which is decision on a case by case basis. I also agree that the examples for changing a building have to do with a function of the building rather than their physical state. They are good examples no critique there, but the examples should unequivocally point to a physical change if they are to be for E81. So if we were to keep the same ones we would need to talk about the physical aspect of the transformation, such as the removal of pews and installation of bookshelves and removal of all holy items and installation of cash registers in order to make a bookstore out of a church (is the change irreversible, is it in fact a transformation or just a modification). Perhaps we could just keep the example of pompeii and of Tut-Ankh-Amun? Otherwise, if we keep the a building example, it should be really characteristic that some physical aspect of its form is changed such that it has a new form. I think we risk that this case will continuously be confused with function. Maybe if we want an architectural example we could talk about the reuse of one building or part of a building being used in construction of another?
I think of the example of the Little Metropolis in Athens: https://en.wikipedia.org/wiki/Little_Metropolis . It is made up of spolia. Some of those spolia were transformed in the construction in order to make new objects. There is a good article on this church here: https://www.academia.edu/2971890/Making_Sense_of_the_Spolia_in_the_Little_Metropolis_in_Athens On page 99 the author talks about an ancient icon of a satyr which is reused. It is castrated and then put in a frame with two crosses. This makes a new object and perhaps achieves our definition of transformation vis a via an object so radically transformed it has a new identity? If not the castrated satyr, there may be other examples of interest in the story of this church https://www.academia.edu/2971890/Making_Sense_of_the_Spolia_in_the_Little_Metropolis_in_Athens E81 examples The castration of the satyr and its joining two two crosses for use in the Little Metropolis Church p123 resulted in The castration of the satyr and its joining two two crosses for use in the Little Metropolis Church resulted in the Little Metropolis Christian Satyr Panel N7 (E22) p124 transformed The castration of the satyr and its joining two two crosses for use in the Little Metropolis Church transformed the pagan Satyr icon (E22) Again there is a change of function and symbolism going on, but there is a particular change in physical form which destroys one object (I assume more than castration went on to get just this figure) and creates a new object (the identifiable panel which has a new composition) We can discuss at SIG whether that makes any sense.
