Understand dynamic frame slot

Is there an existing issue for this?

Summary

当 hosting frame 中有 dynamic frame 时，DU 能听懂 user 说它。

Motivation

这个文档中，我将 dynamic frame 定义为：

1. 在平台上定义 frame Dish，它有slot 叫 name
2. 当name的值是tomato egg noodle，Dish的含义是西红柿鸡蛋面；当name的值是oil spread noodle，Dish的含义是油泼面 也就是说，frame 和它的 slot共同决定了 frame 的含义。

基于 dynamic frame 的思路，#BUC346 在平台上定义如下：

DishCountedDisplayItem: dynamic interface frame

• implements ... frames and has slots:
  • itemId: String
  • itemName: ItemName entity with instance {tomato egg noodle, beef ramen, oil spread noodle} 设置 head annotation
  • itemPrice: Float
  • itemImageUrl: String
  • quantity: int

DishCountedDisplayItemStandard: dynamic concrete frame

• implement DishCountedDisplayItem

CustomSpiceNoodle: dynamic concrete frame

• implement DishCountedDisplayItem
• local slot
  • spice: Spice entity with instance {with spice, without spice}

Note DishCountedDisplayItemStandard 的 itemName 是 {tomato egg noodle, beef ramen} CustomSpiceNoodle 的 itemName 是 {oil spread noodle} 它们的交集为空，并集等于ItemName entity instance

FoodOrdering: intent

• slot
  • mainDish: DishCountedDisplayItem[], with intent VR
  • sideDish: DishCountedDisplayItem[] , with intent VR
• expression
  • $I want to order $mainDish$$

#

我希望 DU 能听懂 user 说：

1. "I want to order tomato egg noodle"
2. "I want to order tomato egg noodle without spice"

Describe alternatives you've considered

舍弃 dynamic frame 的思路，对每一个面 {tomato egg noodle, beef ramen, oil spread noodle} 创建一个对应的 frame。具体设计稍后补充。
