How to import enumeration literals?

How To
1

I have just learned how to create enumerations in UML class diagrams, and to add enumeration literals. The problem is that in my project I would like to create very long enumerations lists, like a list of countries. I have these lists in a Google spreadsheet. Is there any way to import a list to an enumeration?

Ideas for workarounds are also much appreciated!

In this situation, we often need a “documented list”, but not always “all the attributes of the class in the diagram”. In practice, we create a class named “list of countries” and add a reference to a text list or file containing all the names of those countries names.
