When creating a Meta data field element, the data, which the element does work on/with, is the item_metafield_value.value table and column.
For most scenarios, this is sufficient. However, a meta data field has much more information associated with it, eg. the meta field's label. If the label, instead of the value, is what is needed, then the field "item_metafield_label_label" can be added to the element. An addition of such a field changes the data from item_metafield_value.value to item_metafield_label.label. NB! Be aware that labels may have different values depending on the selected language.
There are 26 different fields.
value
The default value of a field, ie this is the value of a meta data field element's field if a field is not specified by the user.

The language versioned label associated with a meta data field.

ItemGuid
A GUID, which maps directly to a meta data field.
