<p>This milestone could be just this, what's different from any other ActivityPub
plugin? How is it better than v2's?</p>
<p>It's better in how it's organised and extensible. See the examples below to have
an idea.</p>
<p>To extend an Activity properties you do:</p>
<pre><code>public function onActivityPubValidateActivityStreamsTwoData(string $type_name, array &amp;$validators): bool {
if ($type_name === '{Type}') {
$validators['attribute'] = myValidator::class;
}
return Event::next;
}
</code></pre>
<p>The Validator should be of the form:</p>
<pre><code>class myValidator extends Plugin\ActivityPub\Util\ModelValidator
{
/**
* Validate Attribute's value
*
* @param mixed $value from JSON's attribute
* @param mixed $container A {Type}
* @return bool
* @throws Exception
*/
public function validate($value, $container): bool
{
// Validate that container is a {Type}
Util::subclassOf($container, Type\Extended\Object\{Type}::class, true);
return {Validation Result};
</code></pre>
<p>To act on received activities do:</p>
<pre><code>public function onActivityPubNew{Type}(&amp;$obj): bool {
</code></pre>
<p>To add information to Activities being federated by ActivityPub do:</p>
<pre><code>public function ActivityPubAddActivityStreamsTwoData(string $type_name, &amp;$type): bool {
</code></pre>
<p>To implement an ActivityStreams 2.0 representation do:</p>
<pre><code>public function onActivityPubActivityStreamsTwoResponse(string $route, arrray $vars, ?TypeResponse &amp;$response = null): bool {
if ($route === '{Object route}') {
$response = ModelResponse::handle($vars[{Object}]);
return Event::stop;
}
return Event::next;
}
</code></pre>
