There are a number of tools for generating forms and requisite client and serverside data validations from JSONschema; but I'm not aware of any for RDFS (and thus the schema.org schema [1]). A different use case, for certain.
It should be possible to model the basics (nested structure, repeated structure, defining the "domain" and "range" of a value).
Schema.org definitions however have no conception of "required" values[], however, so some of the cool form validation we see in some of these tools might not apply here.
[*] _Consumers_ of Schema.org JSON-LD or microdata, however, might define their own data requirements. E.g. Google has some concept of required fields, which you can see when using the Structured Data Testing Tool.
