How to use views hooks - specifically hook_view_data()? I am looking for details on the api to define my own view data, such as what values I can provide for the table I am defining, what values are available for the fields etc.

I have found a tutorial that gives me the basic info, but now I need more specific info.

I have found this page

https://api.drupal.org/api/views/views.api.php/7

but when I click on the link to 

hook_views_data


I go to a page with virtually no information with one link which takes me back to the listing page I started at.

Is there somewhere I can find out information about what hook_views_data should define?
Views does have complete documentation for that hook, but it's not in the most obvious place. 

If you install the Advanced Help module and go to http://mysite.com/help/views/api-tables you'll find the Describing tables to Views help page which contains extensive documentation and code samples.

You can also find the full Views' API docs at http://mysite.com/help/views/api with that module installed.

On top of that, the list of functions that implement hook_views_data() would also be worth a look. The aggregator, book and node module implementations look to be well commented at first glance.
