After a prior talk with Waqar Ahmed I'm moving this issue from GitHub to Jira.

https://github.com/ix-plugin-hub/iocage-plugin-index/issues/125 

To sum up, what we need is to include the category and homepage fields to all plugins in the Index as a mandatory fields. 

We use the Index file for accurate display of available official and unofficial plugins here https://www.truenas.com/plugins/ and here https://www.freenas.org/plugins/  and plan to add search and grouping.
