Instructions and help about Science Of Computer Programming ATL A Model Transformation Tool

uh hello everyone i am dennis vaglar and i will present the atl solution atl emf dvm solution uh to the round trip case um i'm just going to start walking through the code so i'm going to start first with the initial solution that i did which is the most straightforward to understand so in atl basically what you have to do is you work with rules that will traverse the entire model and look for matching instances to transform so this is exactly what i did here so this is a how you would solve task one with a normal atl transformation you have a regular matched rule here which just traverses over all instances you feed into it and will transform it into other instances so it will create a v2 person for every v1 person and it will bind the properties of this v2 person as is listed here yeah so you the name you just copy and what you do here is here you use uh trace um to find if you've already uh transformed the age before or in case you haven't you set it to a default minus one so the tr
