Humans don't model things and the relationships between them, generally.
I'm not sure what you mean by "rendering documents". HTML is not about
rendering, it's about semantics, and at this point is no longer
particularly limited to documents either (applications are often done in
HTML, for instance).

At the moment, such data would be exposed via HTML forms.
If you want to make the data available in a more "raw" form (to enable you
to make custom queries against the data in a way that a form wouldn't let
you) then you're going to have to solve two problems:
1. How to present the raw data to the user in a way that is at least as
understandable as the current form approach, and
2. How to allow you to run these custom queries on the data in a
reliable, standard way that isn't site-specific and doesn't require
you to download the entire data set (since there could be gigabytes
or even terabytes of it).
Neither of these requirements says anything about the data model, format,
or syntax; those are all quite secondary. Both of these problems _must_ be
solved before anyone will consider moving to something other than HTML
forms, IMHO, because otherwise they won't see a compelling reason to move.
They must have a compelling reason to move because it will be a very
expensive process to do so.
(If you want the data available in a form other than HTML forms for a
reason _other_ than being able to query it more effectively, then please
explain the use case, as I don't understand it yet.)
