Semantic Usage

In this scenario, one may wish to see the usage of the semantic element (e.g., glossary term) in the architecture.

In this scenario, from a glossary term or conceptual/logical model element one may wish to simply discover what data element are semantically mapped in the data flow architecture and thus would be impacted by a change to the term or model element.

A semantic usage lineage trace is nearly the reverse of semantic definition lookup. In general it is requested from a term’s or logical model element’s object page. The usage trace itself proceeds down each semantic link and then traces the data flow where there are no transformations (pass-through lineage) to all objects which may be reached in this manner.

Example

Navigate to the term Personally Identifiable Information (PII) in the Finance Glossary. Then click the Lineage tab. Click TREE for the Display As on the right.

On the right hand side panel we see All (note the SHOW setting in the header) and you may see all the terms in the Finance Glossary which are PII, i.e., they are semantically mapped to.

Now, switch to Display As DISPLAY.
