How do you build Wikipedia pages for multiple entities within the same organization?

Multi-entity organizations – parent companies with subsidiaries, holding companies with portfolio entities, conglomerates with multiple notable brands – require careful Wikipedia architecture so each entity is correctly represented and the relationships are machine-readable. The parent-company article covers the corporate entity at the consolidated level: history, leadership, financials, structure. Subsidiaries and notable products get their own articles where standalone notability supports them, with clear cross-linking from the parent article and from each other where the relationships are direct. Wikidata is the structural layer underneath that ties them together: each entity has its own Wikidata item, with explicit parent-subsidiary, owner-owned, and predecessor-successor relationships. That entity infrastructure is what AI engines and the Google Knowledge Graph read to understand the corporate family, and it is what produces accurate disambiguation in AI responses about any one of the entities.
