A suggested requirement for a living knowledge commons wiki
The page content and the page metadata need to be separated, at least in principle, however it is implemented.
Readers need to be able to browse content without the cognitive load of having to read or skip over metadata. Metadata and other semantic material needs to be available not only to machines (as already enabled by e.g. RDFa) but also by people. Metadata can’t always be sensibly represented as content, but is really useful for various reasons.
I envisage a separate metadata page, including the kind of information that is currently shown in “View history” pages; backlinks if they aren’t displayed on the page itself (should be one or the other); permissions; etc. Viewing and edit history are treated separately.
