You can define a field with type 'Study' without declaring it again in
'Denomalised'. Likewise, you don't need to declare TechnologyType multiple
times if they have the same definition. When declaring message fields, you
can reference any type defined anywhere in the same .proto file or in the
imported .proto files. For example:
package mypackage;
message Foo { // Foo #1
optional int32 value = 1;
}
message Bar {
optional Foo foo1 = 1; // This references the first Foo #1.
optional Baz.Foo foo2 = 2; // This reference the Foo #2 defined inside
Baz.
}
message Baz {
message Foo { // Foo #2
optional string description = 1;
}
}
