* added to the item structure (which will need to be saved with item_store eventually).
* If passed an id, the DB is updated, but may not be federated and/or cloned.
* $family - namespace of meta variable
* $key - key of meta variable
* $value - value of meta variable
* $sharing - boolean (default false); if true the meta information is propagated with the item
* to other sites/channels, mostly useful when $item is an array and has not yet been stored/delivered.
* If the meta information is added after delivery and you wish it to be shared, it may be necessary to
* alter the item edited timestamp and invoke the delivery process on the updated item. The edited
* timestamp needs to be altered in order to trigger an item_store_update() at the receiving end.
