That is one thing which us good to start a URI with. If a document is in any way dated, even though it will be if interest for generations, then the date is a good starter. The main reason for not needing the date in this URI is that there is no reason for the persistence of the URI to outlast the magazine. After the creation date, putting any information in the name is asking for trouble one way or another. Authors name - authorship can change with new versions.
People quit organizations and hand things on.
This is tricky. It always looks good at the time but changes surprisingly fast. I discuss this more below. Documents change status - or there would be no point in producing drafts. The latest version of a document needs a persistent identifier whatever its status is.
