Online profiles tend to collapse time. A page displays a current employer, while an old article displays the same current employer even if the work was created years earlier somewhere else. That may be convenient for templates, but it can distort provenance.
Current affiliation answers a present-tense question: where is the professional associated now? Historical attribution answers a different question: who created this work, and what was the relevant relationship when it was created?
These facts can coexist. A professional profile can show current role. An article can identify the author and preserve the publication-time affiliation. If the article is materially revised by a new organization later, the revision record can show who performed the later work.
This separation also helps organizations avoid treating former employees as current representatives. The historical record can continue to credit the work accurately without implying current authorization or employment.
Authority systems become more trustworthy when they represent time explicitly. The web does not have to choose between accurate history and accurate current information; it can maintain both.
