Hi @Matthias , I create a user property like below but it was not saved when i save gds file. If i'm wrong or this is a bug?
thanks, dai
I believe this is not a bug but a specification issue.
If my understanding is correct, a GDS2 file can only carry user properties with integer keys. In contrast, an OASIS file can also carry user properties with string keys.

Thank you, @sekigawa

Yes, exactly. GDS does not support string- or non-integer keys in general, but OASIS does.
@sekigawa Thanks for this elaborate reply!
