EdmModel model = new EdmModel();

EdmEntityContainer container = new EdmEntityContainer("DefaultNamespace", "Container");
model.AddElement(container);

EdmEntityType carType = new EdmEntityType("DefaultNamespace", "Car");
EdmStructuralProperty carOwnerId = carType.AddStructuralProperty("OwnerId", EdmCoreModel.Instance.GetInt32(false));
carType.AddKeys(carOwnerId);

var colorType = new EdmEnumType("DefaultNamespace", "Color", true);
model.AddElement(colorType);
colorType.AddMember("Cyan", new EdmIntegerConstant(1));
colorType.AddMember("Blue", new EdmIntegerConstant(2));

EdmEnumMember enumMember = new EdmEnumMember(colorType, "Red", new EdmIntegerConstant(3));
colorType.AddMember(enumMember);

EdmTerm stringTerm = new EdmTerm("DefaultNamespace", "StringTerm", EdmCoreModel.Instance.GetString(true));
model.AddElement(stringTerm);

var annotation = new EdmAnnotation(
    enumMember,
    stringTerm,
    "q1",
    new EdmStringConstant("Hello world!"));
    model.AddVocabularyAnnotation(annotation);

carType.AddStructuralProperty("Color", new EdmEnumTypeReference(colorType, false));

container.AddEntitySet("Cars", carType);
