It's the base functions that I'm thinking about. This is a revised list:


register_meta_type($type);


Single key=value pair:

 function add_meta($type, $id, $key, $value, $single);

function update_meta($type, $id, $key, $value, $old_value);

function get_meta($type, $id, $key, $value, $single);

function delete_meta($type, $id, $key, $value);


By id:

get_meta_by_id($type, $id);

delete_meta_by_id($type, $id);


By key:

get_meta_by_key($type, $key);

delete_meta_by_key($type, $key);


By type:

get_meta_by_type($type);

delete_meta_by_type($type);


We could also have convenience functions like these:

get_meta_values_by_*()

get_meta_keys_by_*()
