    @nelson given the architecture i'm proposing is effectively the atproto PDS/AppView split, i don't think there's too much that's activitypub-specific here

      @kopper @nelson

      This is marvelous. I wasn't aware of your project, but now I am and added it to the #ActivityPub #C2S tracking list.

      I've also lined up #Outpost for inclusion on the delightful #fediverse curated lists at https://delightful.coding.social

        did some minor updates, no clue if the cached view updated yet but you can read the diff here if you already read the article before:

                  another minor update, fixing a few typos and linking a few more things. also toned down the snark cuz i've been enough of a dick already

                      i should open issues on github.com/swicg/activitypub-api/issues for all my proposals and end up committing 10 faux pas in a row because they still havent decided on if they want a monolithic One Server that replaces the mastodon api or something actually worthwhile to implement

                        @kopper Your opinions are pretty much the same as mine. That's always how I approached my own instance server projects before the requirements inevitably grew way over my head haha

                          also unrelated but i may as well throw this in here since i keep thinking about it but. doing c2s this way also opens your client up to being multi-protocol. say you want to be like wafrn and federate both via ap and atproto, you can then plug in PDSs the same way you plugged in AP C2S servers. your own client can then merge both into one

                          this does lose a handful of the benefits some features mentioned would bring. you would need to store all the data yourself as you'll need your own common API format, you'd need to maintain your own login tokens, your backend would need to act as a proxy for writing to the PDS/C2S server which enables you to cut that off completely if you "go evil". i did touch upon these downsides on
                          w.on-t.work/this-tall-to-interoperate

                          or alternatively, you could have a "personal bridgy" which can be both a c2s client and an atproto client/appview and bridge the objects of an individual actor, irrelevant of which client is used to create them in either direction, but bridging like this isn't really interop because e.g. replies from the other network would not be visible without client support

                            i guess you could make a frontend that talks both APIs natively and picks which one to use depending on how you log in, which would avoid the going evil bit, but that increases complexity on the user's device a fair bit (likely manageable though) and still requires you to proxy the content of the other network as trying to fetch it from the client will either rate-limit/be slow or cause auth failures (e.g. an atproto login trying to fetch AP objects)

                              now that i think about it, you would need actors and logins for both sides anyway if you're doing bridging, this is prolly not an issue

                                  a XRPC endpoint returning AS2-compatible data would be funny

                                      lexicons do have unrestricted json, lexicon validation are there but its not required

                                        @jb no i think validation is important

                                        there is an unknown type but
                                        The (nested) contents of the data object must still be valid under the atproto data model. For example, it should not contain floats. Nested compound types like blobs and CID links should be validated and transformed as expected.

                                          "how to not regret c2s"
                                          w.on-t.work/activitypub/c2s

                                          my opinions about how activitypub c2s ought to be implemented, probably with way too much snark for anyone to take it seriously. wrote pretty much all of it at like 1 am so expect the writing to not be great. will prolly regret it tomorrow but eh. whatever
