* On a general note: Roundtripping data is a very effective method to detect observable differences and bugs that were introduced by the initial codebase conversion. | * On a general note: Roundtripping data is a very effective method to detect observable differences and bugs that were introduced by the initial codebase conversion. | ||

'''ONI files''' are '''modular containers for''' different '''subfile types''', or as we say, '''instances'''. Therefore, ONI files use '''[[XML:TxtC#Example|local IDs]]'''. Eventually, all [[XML:DOOR#File_structure|instances]] become repacked later when the larger level archives (DAT) are rebuilt. | ||
** Therefore, you can define hash parity of output files as a general goal, with the exception that differences can be ignored if they are caused only by non-semantic ID changes. In other words: you may consider semantic equivalence under normalized comparison as sufficient. | ** Therefore, you can define '''hash parity''' of output files as a '''general goal''', with the '''exception''' that differences can be ignored if they are caused only by '''non-semantic ID changes'''.
