My small company develops educational software that teaches algebra, geometry, and other math subjects. The software is designed for desktop Windows PCs. We have a website through which we sell the software, and each software package has its own page.
I would like to add Schema.org markup (using JSON-LD) to these product pages so that our search results listings would be richer and more descriptive. But I am struggling to understand the different types and categories of products that Schema.org defines. My goal is to specify as closely as possible the details of each software product.
For example, I sell a program that teaches high school algebra. If I were to invent my own categories and sub-categories to specify the product I would do it like this:
Product -> Software -> Educational -> Math -> Algebra
But I don't see a hierarchy like that in the Schema.org documentation.
Instead I see the following:
Thing -> CreativeWork -> SoftwareApplication
Within SoftwareApplication I see applicationCategory with "Game" as an example. But I don't see a list of other possible categories, like "Educational". Do you make up your own categories, or do you select from pre-defined choices?
And there is applicationSubCategory with "arcade game" as an example.
I don't know how to view the other possible sub-categories. I would choose "Math" if it is allowed. Additionally, I would like to have a sub-SubCategory, where I would specify "algebra".
Can anyone offer some guidance on how to categorize my products in Schema.org?
