Use WordPress as a Collection Manager. Customize WordPress' post edit screen by creating your own metadata schema's.
You first have to drag it into the user interface. Go to Collections, click on 'User Interface', Create and place a metabox and drag the field in that box.
When you add metadata to a post type, a hint appears above every field how to get the data in the front end. Data that belong to each individual field. The composition differs for each field. The best way to know the fields content is to do this in the right template part (e.g. page.php):
$fieldcontents = get_post_meta($post->ID, collections_fiedname, true); print_r($fieldcontents);
Besides that there is a simple shortcode interface, explained also in this document.
