MODERATORS
Never go for user-submitted / approved by moderator system. I've been in one project like that years ago and it's not gonna work.
I'll make another comment once I get up.
Is there a good reason why? Even MAL takes user submissions.
It's a slow system. MAL takes user submissions because they already have a big database and those submissions help filling the cracks. If you don't have a database to begin with it slows things down, especially if these submissions will go by trust-based. Doing this by randoms is also very risky.
However, I'm not completely oppose to that idea because it can be helpful for some areas. My suggestion is start with a basic dog tag system, where the anime name, alternative names, status (airing, completed), season and start date, studios (also licensors and producers), age rating etc. These information needs to be scraped for the fastest way to form a quick database, they are publicly available (even on Wikipedia) so it should be fine to scrape. You can even go full Wikipedia after got only the names. User submissions could be useful for the introduction / summary parts of the titles at this stage. For only names (and basic tags), you can scrape AniDB from this list. It's just a search query so shouldn't be against their ToS.
You can also check Kitsu for ideas, I like their DB request system. Pretty basic but can be done differently with the power of ActivityPub.
I see. I can use the Jikan API to scrape animes and mangas which will take approximately 1-2 days after I get approval then. Oh and I forgot to mention, the federation part isn't really how people think it will be I guess. The only federation that will be done will be the reviews, threads and the comments in them. With every anime/manga/vn, etc. being a new community which will contain those threads and reviews. And because of that, I don't really know if this project is something people would want to self host. I guess I could provide full dumps of the database every month or something but I suppose that would be expensive. Then there are images as well, which will take hundreds of GBs easily even in compressed form.
Didn't know about Jikan API. After a quick look at their docs, I think it should be a steady source for scraping.
For features, can be done a lot with ActivityPub. Of course the most wanted features would be a watchlist / episode tracker (and possibly an importing from the lists people already have, I switched to Kitsu from MAL that way) but just thinking about federating the all anime/manga titles with basically their own communities out of the box sounds great. Good luck with the project!
Yeah, though I am not sure how the federated instance admins would react. I am planning for every anime, manga, vn, etc. to have their own communities. This means about over 100k communities being made in an instant. Maybe instead of creating the communities in an instant, creating them when user activity first happens would be more fit. But this would also restrict other platforms' users being able to comment on never heard or new anime entries until someone from the anime tracking platform comments or reviews them.
Thanks btw.
Both have ups and downs. Assuming these lists will be in the code, do you have an estimation how big would that be? If you think they won't strangle the code, just go with it. Something like storing them in JSON and loading them when needed could be better for optimization though.
You can also do some best of both worlds, like not creating the communities beforehand but make the titles searchable from the database open for all users. That might require a bigger traffic from hosting side though, but it should be OK since these will be spread to all self hosted communities.
I think you can also ask some of your questions to selfhosted communities.
What do you mean by "lists in the code"? Which lists and do you mean by "in the code" hardcoded?
Well, since 100k titles would make a pretty big database, at least storing the metadata like years, seasons, genres etc as hardcoded could make it run faster than going full-fledged JSON, at least I meant that. However this will be an open source project and there will be localizations, so now it doesn't look like a good idea to me somehow.
What? What do you mean full-fledged JSON. I won't be storing the animes in JSON, but in a PostgreSQL DB. I don't understand what you mean...
Sorry for the confusion. Don't take my words literally, I'm not an expert on databases. I use JSON for my job and it's enough for me, so use what database your project needs. But by full-fledged I meant completely leaning on databases which may slow some things down for the server side. However I now checked PostgreSQL and it seems much better for large datasets, so I don't think that would be a concern for you.
Oh, I see. Ok, I get it now. JSON indeed would be very slow for this project. I also do think of maybe caching some stuff for this reason.
Yeah, that would be nice for the running seasons I guess. Maybe even a couple years worth seasons since most of the traffic will come from those.
Yep, that's what I was thinking.
Noticed the edit:
For hosting images, you can go alternatives like some Lemmy sites do: Mirror everything automatically to Internet Archive.
I think people would want to self host, because they will get all the anime/manga titles with their communities out of the box and can moderate their own sites while their users can react to any other community via federation.
Wouldn't Internet Archive be a bit slow? And also, I don't want to stress their servers.
That's a noble concern. I just gave an example there since some communities do that but yeah it would be better if not done I guess.
Also mentioned on other reply but you can ask this to !selfhosted@lemmy.world and probably will get an optimized answer regarding that issue.
Thanks.
You're welcome, and good luck!
I think moderator approval is a bit slow
It is, but I have no choice other than that if I can't scrape websites.
Could be like anyone can post, but if it's downvoted it's hidden, Reddit style
That seems like a good idea. I'll keep it in mind.
