- | ## Domain Specific Language for types Fields may be tagged `typeDSL: true` in `jsonldPredicate`. If so, the field is expanded using the following micro-DSL for schema salad types: * If the type ends with a question mark `?`, the question mark is stripped off and the type is expanded to a union with `null` * If the type ends with square brackets `[]` it is expanded to an array with items of the preceeding type symbol * The type may end with both `[]?` to indicate it is an optional array. * Identifier resolution is applied after type DSL expansion. ### Type DSL example Given the following schema: ``` - $include: typedsl_res_schema.yml - | ``` Process the following example: ``` - $include: typedsl_res_src.yml - | ``` This becomes: ``` - $include: typedsl_res_proc.yml - | ```
