My question is about adding Schema.org markup for a B2B website, wherein X is the parent company and Y is an entity of the parent company.
Since we cannot add an Organization markup to Y which is an entity, what other Schema.org markup would be applicable to Y?
回答1:
I would suggest that you use Organization for Y and specifiy the relationship between X and Y using the departement property of Organization ( in Y).
https://schema.org/Organization https://schema.org/department
回答2:
To relate two Organization (or sub-types of Organization) entities, these are the possible properties (as of version 2.2):
- brand
- department
- member / memberOf
- parentOrganization / subOrganization
According to your description, parentOrganization (or the inverse subOrganization) seem to be appropriate.
