Name and Identifier
The name and the identifier are two of the values you can ask for when querying the shape of an item. The former returns the name itself while the latter return the an easily discernible name and is assigned to the shape at the time of creation. You can change the shape name but the identifier is unchangeable and cannot be edited at a later time.
To fetch the shape of an item, you can use the shape field. The field return information such as the name, identifier, meta property and the creation date.
