Post types in the plugin

Hi –

Can someone please give me the lowdown on the post types / taxonomies / etc used in this plugin? I’d like to add custom values to various things.

So far I’ve managed to add custom taxonomies to the ‘event’ post type, but I’d like to know what ‘Locations’ are and if I’m able to add custom metadata to them (without using the custom attribute element – doesn’t work they way I’d like) by adding some code to my functions.php.

For example, I’d like to add links to the venues’ social media pages. That’s just for starters. Can anyone advise?

Thanks.
