Education Major Lookup Management for Talent Person Profiles

Summary: Curious to understand how other groups capture and manage Education> Major information within Person Profiles.

Content (required): We maintain an item catalog for Education majors for the Person Profile, used on the Skills and Qualifications page. It looks like some groups opt to only use a open/free text field for majors, but for others that use common lookups, can you share best practices or strategy on how you maintain your list of lookups? So do you have external source standards you consult, partnerships, etc.,?

For additional background, we do not have Oracle Recruiting or LinkedIn Profile connections enabled today for our person profiles.
