Universal Data Element Framework
The Universal Data Element Framework (UDEF) provides the foundation for building an enterprise-wide controlled vocabulary. It is a standard way of indexing enterprise information that can produce big cost savings. UDEF simplifies information management through consistent classification and assignment of a global standard identifier to the data names and then relating them to similar data element concepts defined by other organizations. Though this approach is a small part of the overall picture, it is potentially a crucial enabler of semantic interoperability.
== How UDEF works ==
UDEF provides semantic links, through assigning an intelligent, derived ID as an attribute of the data element, essentially labeling the element as a specific data element concept. When this UDEF ID exists in both source and target formats, it can then be used as an easy analysis point via a match report, and then as the primary pivot point for transformations between source and target.
UDEF takes a list of high-level root object classes and assigns an integer to each class plus alpha characters to each specialization modifier. It then also assigns integers to property word plus integers to each specialization modifier. These object class alpha-integers are concatenated together with the property integers to form a dewey-decimal like code for each data element concept.
