I just stumbled across this website.

It basically takes WHS data that is locked up in word files and pdfs and turns them into HTML, that is in a regular repeated format.

It currently only has natural WHS in it.
Here is an example: Aldabra Atoll

There are links to a World Heritage Knowledge Lab (but it is a blank 404) and a GitHub repository
