如何将事物的集合描述为 ALPS 描述符中的词汇属性？

Question

为了以应用程序为中心来描述 REST API，我正在尝试使用 ALPS 描述符及其工具。

假设我有一个对象“艺术品”，一件艺术品具有以下属性：标题、艺术形式、作者等。

我应该如何描述属性“作者”？在 OpenAPI 规范中这很简单，只需说“type: Array”，然后在“items”下指定引用。在 ALPS 中描述集合的等效方式是什么？

我使用 YAML 格式来描述 API。

我当前的描述符如下所示：

descriptors:
# vocabulary properties
- id: "identifier"
  type: "semantic"
  text: "Unique identifier within Alpha Org. This is not the serial number of the item. This identifier is automatically generated when a new artwork item is created in the system."
  ref: "https://schema.org/identifier"

- id: "headline"
  type: "semantic"
  text: "Title of the artwork"
  ref: "https://schema.org/headline"

- id: "artform"
  type: "semantic"
  text: "Form of the artwork: painting? photograph? sculpture? others?"
  ref: "https://schema.org/artform"

- id: "authors"
  type: "semantic"
  text: "Authors of this artwork"
  ref: "https://schema.org/author"

- id: "serialNumber"
  type: "semantic"
  text: "Serial number of the artwork. If the artwork does not have a serial number, such as an original painting from an artist, then this number is simply the examplar number, usually 1."
  ref: "https://schema.org/serialNumber"

- id: "description"
  type: "semantic"
  text: "Description of the artwork"
  ref: "https://schema.org/description"

- id: "obtainDate"
  type: "semantic"
  text: "Date on which Alpha Org obtained the ownership of this artwork."
  ref: "https://schema.org/Date"

- id: "itemLocation"
  type: "semantic"
  text: "Location of the storage of the artwork item"
  ref: "https://schema.org/itemLocation"

- id: "images"
  type: "semantic"
  text: "Images of the artwork"
  ref: "https://schema.org/image"

ALPS 描述不区分单个项目和集合。从模型 POV 来看，任何东西都可以是一个集合，从实现 POV 来看，实现该 ALPS 描述的每个服务都会做出自己的决定。

作为一种常见做法，我通常在重要时使用 IANA 链接相对值

rel: item and rel: collection

有一个小实用程序 (ALPS UNIFIED) 展示了如何将 ALPS 描述转换为 OpenAPI 定义： https://github.com/mamund/alps-unified
