What is the correct use of parentOrganization and subOrganization?

[alvaropicho]

Until I'm not an experienced in the creation of Schemas, a doubt arises to me, and I believe that I can raise well.

When I make use of the parentOrganization property, one of these 2 readings/interpretations is valid, but I'm not sure which one is correct.

First, the schema, when I write:
{
"@type": "Organization",
"@id": "https://website.es/#organization",
"name": "Organization 1",
"legalName": "legal name company",
"url": "https://site.com/",
"logo":".....png",
"parentOrganization":
{
"@type": "OnlineBusiness",
"name": "name1",
"legalName": "legal name company",
....

My dount, Am I declaring...:

1. That Organization 1 IS the parentOrganization of an OnlineBusiness.

So I subordinate OnlineBusiness to Organization. Is this correct?

2. Or is the statement the other way around: that Organization 1 HAS a parent Organization that is an Online Business.

Semantically the question is, which is correct.

1. This IS that

Or

2. This HAS that

I think the correct is 1). Am I wrong?

Now the case with subOrganization.

My Case is a Research Center of a College, one of many over the College.

First I built:

Research Center -> ParentOrganization -> College

Because I think the sentence was:

Research Center HAS a parent Organization that is the College.

But days after, I think I'm wrong and i think the best Schema is:

Reseach Center -> sub Organization -> College

So the sentence is:

The Research Center IS a sub Organization of the College.

And I close the circle, which is the correct lecture with both types (parent and sub)?

1. This IS that
2. This HAS that

I think, nº 1 is the correct but I'm not sure...

Any advice will be very welcome.

With love & respect,

The sentence construct I would use is:

Organization A's parentOrganization is Organization B

In the same way that

Organization A's founder is A. Person

or

Organization A's telephone is 08000 111 11111

Coming at it from the other direction...

Organization B's subOrganization is Organization A

Thank you very much @RichardWallis

Your answer will help me over all schema's types and properties.

Even, this sentence construct has a stronger logical, easy to manage, because a property/value, is held, it has.

For me, from now on I'll tell myself: THIS HAS this property that IS THAT type

I'm really happy, thank you again Richard
