Do we have a formalized ‘data dictionary’ document that outlines the fields that come out of HCM?

Hello everyone,

Do we have a formalized "data dictionary" document that outlines the fields that come out of HCM, the possible options of them, and how they are used and/or context around them?

For example, the difference between person type and worker type. What's the definition of each, what are the options for each, how are each used and understood?

Thanks,

Venkat.
