"Reliably Maintaining Organization Markup" is discussed here from the perspective of "Entity Identity and Relationships." For SEO teams and developers, "Verified Core Identity" and "Mixed Companies" are particularly important.

What real-world business data belongs in a well-maintained organization markup?
Name, URL, logo, and a stable ID form the basis; legal name, address, contact point, or sameAs are only added if they correspond to the real entity and are maintained. A central business source consistently distributes changes to the homepage, location models, and dependent content.
Appropriate contact point
Clarify the real company, brand, and operator roles, and define a canonical organization with a stable ID.
Maintain core fields from verified sources and review optional contacts and profiles for purpose and currency.
Compare output on the homepage, site pages, and dependent entities, and centrally roll out versioned changes.
Implementation Case: "Mixed Entities"
A brand is operated by two companies in different countries. Instead of combining both addresses into one organization, the brand retains its identity, and each operator receives its own ID; contact points and relationships are assigned to the actually responsible entity.
Mixed Entities
Mixed Entities – The brand, parent company, and local operator are combined into one entity and have conflicting names or addresses.
Unmanaged Contact – An old telephone or general mailbox remains structured and marked up, even though no inquiries are processed there anymore.
Arbitrary identity links Press mentions and thematic partner pages appear as sameAs even though they do not represent the same organization.
