I am writing a big piece of structured data for a large organization who have acquired many organizations over the years, merging the old organisation names into the current company.

There isn't currently a way to accurately describe this.

I am currently using Organization (Company A) > subOrganization (Company B)
Company B then has a dissolutionDate specified
Company A's sameAs also contains Company B's sameAs

I therefore propose a new schema property called "rebrandedTo".

This would only accept the following types:

• Organization (and all its subtypes)
• LocalBusiness (and all its subtypes)

and be used on the following types:

• Organization (and all its subtypes)
• LocalBusiness (and all its subtypes)

This new property would be used to describe Organizations or LocalBusinesses which have been acquired by another business or merged into that business.

It would be even better if we could have a property such as "rebrandDate" to say the date when Company B was rebranded as Company A.

I imagine it would look something like this:
{ "@type": "Organization", "name": "Company A", "@id": "https://www.example.com/#organization", "alternateName": ["Company B"], "legalName": "Company A Inc.", "subOrganization": [ { "@type": "Organization", "name": "Company B", "legalName": "Company B, Inc.", "dissolutionDate": "2022-11-03", "rebrandedTo": { "@type": "Organization", "name": "Company A", "@id": "https://www.example.com/#organization", "rebrandDate": "2022-11-03" } }

If there is currently a better way of doing this that I've not found, please can you let me know. Thank you very much
