Yes, of course one could also hunt dogs with ducks, but in practice that doesn't work so well. The point isn't whether or not I approve of hunting ducks with dogs (or vice versa); to be clear, I don't. The point is that it's a pub related to an activity, and is therefore an [ActivityPub](https://www.w3.org/TR/activitypub/). + +Are we clear? + +Good. + +Let us proceed. + +**The Old Dog and Duck** is intended to be a set of libraries to enable people to build stuff which interacts with ActivityPub. It isn't intended to be a replacement for, or clone of, Mastodon. I do think I might implement my own ActivityPub server on top of The Old Dog and Duck, that specifically might allow for user-pluggable feed-sorting algorithms and with my own user interface/user experience take, but that project is not (yet, at any rate) this project. + +## Status + +This is a long way pre-alpha. Everything will change. Feel free to play, but do so at your own risk. Contributions welcome. + +## Architecture + +There are a number of separate concerns required to implement ActivityPub. They include + +1. Parsing ActivityStreams messages received from peers and from clients; +2. Persisting ActivityStreams objects; +3. Delivering ActivityStreams objects to peers; +4. Delivering ActivityStreams objects to clients. + +**NOTE THAT** what Mastodon delivers to clients is not actually in ActivityStreams format; this seems to be an ad-hoc hack that's just never been fixed and has therefore become a de-facto standard for communication between ActivityPub hosts and their clients. + +My proposal would be to deliver exactly the same ActivityStreams format to my client as to other servers. There may be a valid reason for not doing this, but if there is I will discover it in due course. + +## Proposed dog-and-duck libraries + +**NOTE THAT** at the present stage all the proposed libraries are in one package, namely this package, but that it is proposed that in future they will form separate libraries in separate packages. + +### Bar + +Where conversations happen. Handle interactions with clients. + +### Cellar + +Where things are stored. Persistance for ActivityStreams objects; I may at least initially simply copy the Mastodon postgres schema, but equally I may not. + +### Pantry + +Where deliveries are ordered and arrive; and from where deliveries onwards are despatched. Handle interactions with peers. + +### Quack + +Duck-typing for ActivityStreams objects. + +As of version 0.1.0, this is substantially the only part that is yet at all useful, and it is still a long way from finished or robust. + +### Scratch + +What the dog does when bored. Essentially, a place where I can learn how to make this stuff work, but perhaps eventually an ActivityPub server in its own right. + +## Usage + +At present, only the duck-typing functions work. To play with them, use + +```clojure +(require '[dog-and-duck.quack.quack :as q]) +``` + +## Testing + +Prior to testing, you should clone [activitystreams-test-documents](https://github.com/w3c-social/activitystreams-test-documents) into the `resources` directory. You can then test with + +```bash +lein test +``` + +## License + +Copyright © Simon Brooke, 2022. + +This program and the accompanying materials are made available under the +terms of the GNU General Public License as published by the Free Software Foundation, either version 2 of the License, or (at your +option) any later version. diff --git a/docs/cloverage/clj_activitypub/core.clj.html b/docs/cloverage/clj_activitypub/core.clj.html new file mode 100644 index 0000000..d0e28ea --- /dev/null +++ b/docs/cloverage/clj_activitypub/core.clj.html @@ -0,0 +1,449 @@ + + + + clj_activitypub/core.clj + + + + 001  (ns clj-activitypub.core +

NOTE THAT The ActivityStreams spec says:

+
+

All properties are optional (including the id and type)

+
+

But we are just not having that, because otherwise we’re flying blind. We shall reject objects lacking at least :type. Missing :id keys are tolerable because they represent transient objects, which we expect to handle.

Transient objects in ActivityPub are not required to have an id key, but persistent ones must have a key, and it must be an IRI (but normally a URI).

The Old Dog and Duck

+

A Clojure library designed to implement the ActivityPub protocol, obviously.

+

Introduction

+

The Old Dog and Duck is clearly a pub, and it’s a pub related to an activity; to whit, hunting ducks with dogs. Yes, of course one could also hunt dogs with ducks, but in practice that doesn’t work so well. The point isn’t whether or not I approve of hunting ducks with dogs (or vice versa); to be clear, I don’t. The point is that it’s a pub related to an activity, and is therefore an ActivityPub.

+

Are we clear?

+

Good.

+

Let us proceed.

+

The Old Dog and Duck is intended to be a set of libraries to enable people to build stuff which interacts with ActivityPub. It isn’t intended to be a replacement for, or clone of, Mastodon. I do think I might implement my own ActivityPub server on top of The Old Dog and Duck, that specifically might allow for user-pluggable feed-sorting algorithms and with my own user interface/user experience take, but that project is not (yet, at any rate) this project.

+

Status

+

This is a long way pre-alpha. Everything will change. Feel free to play, but do so at your own risk. Contributions welcome.

+

Architecture

+

There are a number of separate concerns required to implement ActivityPub. They include

+
    +
  1. Parsing ActivityStreams messages received from peers and from clients;
    2. +
  2. Persisting ActivityStreams objects;
    3. +
  3. Delivering ActivityStreams objects to peers;
    4. +
  4. Delivering ActivityStreams objects to clients.
    5. +
+

NOTE THAT what Mastodon delivers to clients is not actually in ActivityStreams format; this seems to be an ad-hoc hack that’s just never been fixed and has therefore become a de-facto standard for communication between ActivityPub hosts and their clients.

+

My proposal would be to deliver exactly the same ActivityStreams format to my client as to other servers. There may be a valid reason for not doing this, but if there is I will discover it in due course.

+

Proposed dog-and-duck libraries

+

NOTE THAT at the present stage all the proposed libraries are in one package, namely this package, but that it is proposed that in future they will form separate libraries in separate packages.

+

Bar

+

Where conversations happen. Handle interactions with clients.

+

Cellar

+

Where things are stored. Persistance for ActivityStreams objects; I may at least initially simply copy the Mastodon postgres schema, but equally I may not.

+

Pantry

+

Where deliveries are ordered and arrive; and from where deliveries onwards are despatched. Handle interactions with peers.

+

Quack

+

Duck-typing for ActivityStreams objects.

+

As of version 0.1.0, this is substantially the only part that is yet at all useful, and it is still a long way from finished or robust.

+

Scratch

+

What the dog does when bored. Essentially, a place where I can learn how to make this stuff work, but perhaps eventually an ActivityPub server in its own right.

+

Usage

+

At present, only the duck-typing functions work. To play with them, use

+
(require '[dog-and-duck.quack.quack :as q])
+
+

Testing

+

Prior to testing, you should clone activitystreams-test-documents into the resources directory. You can then test with

+
lein test
