将 'license' 字段添加到 schema.org 地方记录

Question

我有一个位置数据库，我想将其发布为开放数据。每条记录都可以有多个许可证之一，具体取决于数据的来源，因此每条记录都需要附加一个许可证。我将数据发布为 json-ld。示例记录：

{
  "@context": "http://schema.org",
  "@type": "Place",
  "name": "METROPOLITAN MUSEUM OF ART",
  "address": {
    "@type": "PostalAddress",
    "streetAddress": "1000 5TH AVE",
    "addressLocality": "NEW YORK",
    "addressRegion": "NY",
    "addressCountry": "United States",
    "postalCode": "10028-0198"
  },
  "hasMap": "http://www.openstreetmap.org/?mlat=40.7784&mlon=-73.9627#map=15/40.7784/-73.9627",
  "geo": {
    "@type": "GeoCoordinates",
    "latitude": 40.7784,
    "longitude": -73.9627
  },
  "description": null,
  "telephone": "+1 (212) 472-2764",
  "url": "http://www.metmuseum.org",
  "openingHours": null,
  "photo": {
    "@type": "ImageObject",
    "contentUrl": "http://127.0.0.1:8888/fSunhLAJFSmnx55GNJee2-YKcgE=/1000x1000/museums/logos/000/149/449/original/NYC_-_Metropolitan_-_Temple_of_Dendur.JPG",
    "creator": "Jean-Christophe BENOIST",
    "license": "CC BY 3.0"
  }
}

如果可能，schema.org Place model doesn't have a field for 'license'. What is the correct way to add a license type field to the record? Essentially I want to embed a CreativeWork 字段。

Answer 1

您似乎想为关于 Place 的文档提供许可，而不是 Place 本身。

所以选择 CreativeWork (or one of its sub-types, like WebPage if the document is a web page) and make use of its license 属性。

要说明此 CreativeWork 与 Place 有关，您可以使用 about property, and to state that the Place is the primary entity described in this document, you could use the mainEntity 属性.

如果你想保持Place为顶级节点，你可以使用JSON-LD的@reverse for the about property, and use mainEntity’s inverse property, mainEntityOfPage.

Answer 2

使用 http://schema.org/Dataset (which is a type of CreativeWork) will allow you to set a license. Place is a field within Dataset so they fit together. The license for your ImageObject should also be the URL of the license 而不是文本（这是我在遇到问题后发现的）。

数据集包括datasetTimeinterval、distribution、includedDataCatalog和spatial（一个Place）。数据集只有 introduced in May
