How to associate any array of entities with a page-like entity

What I'm trying to do is have a page-like entity, associated with an array of items (perhaps other pages, or links... the idea is this array will extend)... But not sure how to do this. This is how the set config is for regular pages:

elgg_set_config('pages', array(

'title' => 'text',

'description' => 'longtext',
'tags' => 'tags',
'parent_guid' => 'parent',
'access_id' => 'access',
'write_access_id' => 'write_access'));

So would I do something like this for my new page entity?

elgg_set_config('new_pages', array(

'title' => 'text',

'description' => 'longtext',
'tags' => 'tags',
'parent_guid' => 'parent',
'access_id' => 'access',
'write_access_id' => 'write_access'),

'listOfLinks' => 'array');

 

Appreciate any help. Thanks.
