Use sameAs references selectively instead of indiscriminately

Which external profiles are suitable for a credible sameAs referral?

A suitable target uses consistent core data and is controlled by the entity or managed by a reliable authority. The list remains small, verifiable, and entity-specific; general social media posts, partner pages, and thematic sources are linked via regular links rather than identity relationships.

Practical Example: "Mention as Identity"

A person entity links to the official university profile and a clearly managed professional account. An interview, a namesake, and the employer's website remain normal context links because they do not represent the same person.

Mention as Identity

• Mention as Identity A press article about the company is linked, even though the page itself does not represent the same organization.

• Incorrect Name Profile A similarly named account belongs to a different person or brand and connects two independent entities.

• Orphaned Account An abandoned or transferred profile remains in the markup for years and now carries conflicting identity signals.

Identical Object

• Identical Object – Name, role, location, or other core data demonstrate that the destination and exit point truly refer to the same real entity.

• Authoritative Landing Page – The profile is controlled by the entity itself or clearly assigned by a trusted institution.

• Continuous Auditability – URL and profile status can be regularly checked for accessibility, changes in ownership, and inconsistencies.

Authoritative Landing Page

1. Collect existing references for each entity and evaluate destinations based on self-control, institutional authority, and unambiguous core data.

2. Maintain only verified identity targets at the stable entity ID and convert all thematic sources to normal linking.

3. Regularly check reachability, ownership, and data consistency, and remove questionable or outdated targets without replacement.

Continuous Auditability

• Percentage of maintained sameAs targets with documented identity verification and consistent core data for the source entity.

• Number of unreachable, transferred, or only thematically related URLs that are removed during regular review.

sameAs is a strong equality statement and should therefore be used sparingly. A few verified targets clarify identity better than a long list of related pages.
