The Universal Data Element Framework (UDEF) was
/ref> a controlled vocabulary developed by The Open Group. It provided a framework for categorizing, naming, and indexing data. It assigned to every item of data a structured alphanumeric tag plus a controlled vocabulary name that describes the meaning of the data. This allowed relating data elements to similar elements defined by other organizations.
UDEF defined a Dewey-decimal like code for each concept. For example, an "employee number" is often used in human resource management. It has a UDEF tag a.5_12.35.8 and a controlled vocabulary description "Employee.PERSON_Employer.Assigned.IDENTIFIER".
UDEF has been superseded by the Open Data Element Framework (ODEF).https://www.opengroup.org/open-group-semantic-interoperability-work-group/UDEF

Examples
In an application used by a hospital, the last name and first name of several people could include the following example concepts:
*Patient Person Family Name – find the word “Patient” under the UDEF object “Person” and find the word “Family” under the UDEF property “Name”
*Patient Person Given Name – find the word “Patient” under the UDEF object “Person” and find the word “Given” under the UDEF property “Name”
*Doctor Person Family Name – find the word “Doctor” under the UDEF object “Person” and find the word “Family” under the UDEF property “Name”
*Doctor Person Given Name – find the word “Doctor” under the UDEF object “Person” and find the word “Given” under the UDEF property “Name”
For the examples above, the following UDEF IDs are available:
*“Patient Person Family Name” the UDEF ID is “au.5_11.10”
*“Patient Person Given Name” the UDEF ID is “au.5_12.10”
*“Doctor Person Family Name” the UDEF ID is “aq.5_11.10”
*“Doctor Person Given Name” the UDEF ID is “aq.5_12.10”
