Editorial summary

Begin with the source’s own compact description: “Seo Yong-duk” is south Korean association football player. The dossier treats that line as a proposition to test through Yong-duk, South and Korean, not as a finished interpretation.

Editorial reviewA useful biographical orientation record, particularly for establishing names, roles and a first chronology. The current lead gives the account dated anchors—1989, 2009—that can be checked directly. The linked authority record independently contributes the date 1989-09-10. For this dossier, Yong-duk, South and Korean is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “south Korean association football player” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Jul 26, 2026. The linked authority identifier is Q491875. VIAF identifies the subject as 138153061343619202778. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1989 and 2009.

Critical limits

Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
