Hi @asmecher!

I've created draft PRs, later I'll recheck if the basic features (import/export through the CLI and web interface) are still working fine after rebasing.

I've been using these updates to import data locally, and everything seems to be working fine... Most of the changes are additions. The modified parts are inside classes related to the native import/export plugin.

[asmecher]

@defstat, could you review these?

@jonasraoni, I'm assuming you went back to the commits where this was first added to main and cherry-picked them to stable-3_3_0? Or did you bring in the files from main and back-port them to compatibility with stable-3_3_0 again? Just to know what to look for.

[jonasraoni]

If I remember well:
#7640: Cherry picked the first commit + adjusts.
pkp/ops#223: Grabbed the needed files from /main + adjusts.

@jonasraoni, that's a lot more code being added to stable-3_3_0 lib/pkp than I expected naively; is there really no impact on the OJS and OMP stable branch?

[jonasraoni]

@asmecher I just checked and I fully agree, I think these PRs were a kind of draft.
I'll check if it's possible to decrease the amount of changes.

Anyway, let me know if you're ok to get this amount of code merged in 3.3.0... Then, given that most of changes are additions, I can just test the updates against OJS/OMP.

[asmecher]

Unless the potential impact can be brought down on OJS/OMP 3.3.0-x, I'd suggest just leaving these changes to the 3.4.0 release. If someone has a firm requirement for this support in 3.3.0-x, please speak up!

[asmecher]

Let's leave this as a thing to be added to an install for anyone who needs it -- but unless there's a compelling reason to merge disruptive changes to stable-3_3_0 (especially for pkp-lib) I'd rather not merge. Thanks all!

[jonasraoni]

Yeah! That's what I've told to Michael. It's still useful for those who really need to import data into OPS 3.3 :)

Also, I can confirm all the code here can be applied temporarily, just to get the imported data in place, then it might be fully reverted to the base branch (stable-3_3_0) without issues.
