Currently the schema package returns all skills, domains and modules by extracting them from the record's schema. In case of modules it is not even the complete schema, as it probably lacks the objects it refers to.

The purpose of the GetSchemaSkills etc. functions it to be able to browse the class taxonomy, for which it would be better if these returned the taxonomy tree as a Go struct with {Name, Id, SubClasses} that is easier to browse. For the input, the OASF SDK could use the output of the /api/skill_categories etc. endpoints.
