@smallcircles🫧 socialcoding.. @evanEvan Prodromou An AS2 Collection cannot be a timeline (in general). It’s not even ordered. An AS2 OrderedCollection (a subtype of Collection) might be ordered by time or not, so it’s also not a timeline (in general). When they are ordered by some time value (unspecified in AP) they are often called “streams” in the spec. The Mastodon content timelines are not the same as AP activity streams although a filtered AP stream can be transformed to a content timeline.

@smallcircles🫧 socialcoding.. To follow up on the discussion from yesterday, @evanEvan Prodromou has created a proposal for another kind of “event stream” that is not necessarily associated with *any* AP collection type (see Example 1). This is more aligned with my mental model of an event feed/stream, where a timeline^1 is the history of the feed after optional filtering and content materialization. (^1 However, the terms are often used interchangeably in the Fedi.)
