Stricter specifications for pagination of Collections and OrderedCollections

What do you mean by that?

When I said “latest version” of an activity object, I meant the currently stored activity object state rather than that the object was being versioned in some way. I don’t see any mention of versioning any kind of data in the spec.

I’m thinking of dereferencing a resource/object given an IRI rather than dereferencing a server. The definition I’m using is similar to this SO answer: “all URIs you can map to a resource can be considered dereferenceable”.

A C2S Update is instructing the server to partially update an existing target object using specific instructions about which properties to replace, add or remove. Whatever is processing the update only has the target object IRI and the update instructions. In that sense, it must “dereference” the IRI to update the existing object. Is there a different terminology you prefer for that?
