Hey! I’d love to work on adding support for the Folksonomy engine as part of GSoC 2025. Assigning myself now.

[Freso]

Given that Tejaswi-Bikkavolu never submitted a PR, and hahacen’s PR hasn’t gotten any attention from hahacen since its submission almost 10 months ago, I went ahead and started work on my own attempt at implementing this: #418

Feel free to assign me to the issue.
