I am trying to improve my website's SEO by getting our results to appear in the Knowledge Graph. The challenge I am having is that the website is for a product sold by a sub-brand of a larger organisation. What would be the best way to categorise this in Schema markup? Currently it is not appearing by using the sub-brand name in "Organization","name".
For example, what would the website markup be for PlayStation being part of the larger organisation of Sony? Are there defined categories for this in Schema?
