Project Legacy · Source Vocabulary
Keep the source’s vocabulary intact.
The DII Trust publishes separate site, occupation, industry and entity code lists. Legacy preserves those source taxonomies as orientation tools rather than silently merging them into a single exposure conclusion.

Why separate taxonomies? A source may use one vocabulary for occupations, another for industries, another for entities and another for sites. Keeping those layers separate makes later reconstruction more accurate and prevents a code-list term from being mistaken for proof of a person’s history.
Evidence boundary
These are source-specific taxonomies. Their presence in official trust materials is useful for research orientation, but the current governing trust documents control and person-specific facts still require their own evidence.
