Thanks, this is useful. I only posted under feature requests because I'm new and don't yet know how things work around here. I now know that this would have to be implemented as a plugin, and I suspect that it will not be too difficult. That is a lot more than I knew yesterday!

I'm just getting started with nodeBB. I would really like to associate key-value pairs with topics. That is, I want to be able to tag a topic with things like "priority: low" or "prog_lang: julia". The only thing I found so far is https://community.nodebb.org/topic/1858/embedded-metadata-for-posts-and-other-objects.

Any thoughts about the feasibility of this would be appreciated.
