I’ve just installed a new instance of NodeBB and it works beautifully. Some questions:

1. Is it possible for categories to follow Lemmy communities in their sync settings? I seem to be able to follow Lemmy communities, but the categories are stuck on pending.
2. Same for NodeBB categories. Can I sync my own category with remote NodeBB categories?

Edit: the URLs stuck on pending are giving “invalid-id” errors in the log. As in invalid activitypub ids. I pasted the URLs of some Lemmy communities and NodeBB categories.

Edit 2: Found the topic about this. https://community.nodebb.org/post/102818

projectmoon@forum.agnos.is

It seems community.nodebb.org declined to respond to the data request. The link will still work, but no preview is available.

NodeBB Community

1. Is currently outstanding: https://github.com/LemmyNet/lemmy/issues/5354

2. You should be able to do this, although I may have to double check the logic. There have been reports that it is not working as expected.

I’m wondering, as a stopgap solution, would it make sense to have some kind of rules engine that allows topics coming in from the fediverse to automatically be moved to NodeBB categories? Kind of like a somewhat less elegant sync.

Edit: like automatically assigning incoming topics based on tags seems like a particularly easy solution?

@projectmoon@forum.agnos.is thanks for the suggestion, that’s definitely something I’d want to consider.

Sort of a post queue for federated content that needs automatic or manual review before it is automatically slotted in a category.

@julian@community.nodebb.org Thanks. Even something as simple as mappin topic tags to categories automatically would work I think.

@projectmoon@forum.agnos.is careful with that though, not all tags are the same, some have a higher signal-to-noise ratio, but others would just be filled with garbage

I think the best way, then, would be to have rules that map various group actor URLs to categories, and possibly also tags. Nothing automatic. Only configured. Of course, once Lemmy fixes the ability of Group actors to follow other Group actors, this will be a non-issue.

One other possible solution, which is employed by Misskey et al., is a proxy actor. It’s a special user that follows other users, and relays info within its own instance. It’s used for doing things like adding a remote user to a list without directly following them. The proxy account follows the user, and then your local instance adds the remote user to your list. But all ActivityPub interactions go through the proxy user.

If you have deployed NodeBB v4, and you updated to v4.0.1, please update now to v4.0.2 which fixes a regression that silently broke outgoing user follows.

Do we need need to refollow?

@projectmoon@forum.agnos.is if you browse to the account it will show as unfollowed, so you will need to refollow, yes.

@julian I’ve been unable to get AP following to work in either direction. I mean it is sometimes possible to follow somebody and get followed by other sites, but no actual posts ever come into or out of my nodebb instance (forum.n66.pl). The only thing that works is importing posts directly by entering their URL in the search area, which is also temperamental – sometimes the same post can be imported and sometimes it can’t. I also tried following people from individual categories. It never worked except for one instance where it seems to have been stuck with a “pending” message, but I have no way of accepting or rejecting the follow request on the other side (it should be accepted automatically). Sometimes the same happens when entering followed people’s URLs in the search panel. Looking forward to fixes.
