这是正确的解决方案：

{
  "@context": "http://schema.org/",
  "@type": "Book",
  "name": "Gone With the Wind",
  "encoding": {
    "@type": "MediaObject",
    "contentSize": "2.1 megabytes",
    "encodingFormat": "PDF"
  },

Answer 2

PDF 是电子书

如果 PDF 包含一本书，则它是一本电子书。（参见维基百科：E-book: Formats and Comparison of e-book formats: Portable Document Format）。

所以对于这样的PDF，提供一个Book with bookFormat = https://schema.org/EBook.

如果要提供电子书的文件类型，可以使用fileFormat property with a value of application/pdf (IANA Media Types).

多种格式的书

当您提供不同格式的书籍（平装本、多本电子书等）时，您应该使用一个 Book 项目代表作品，另一个 Book 项目代表每种格式.

你可以 link 他们 workExample 属性:

Example/instance/realization/derivation of the concept of this creative work. eg. The paperback edition, first edition, or eBook.

JSON-LD示例

{
  "@context": "http://schema.org/",
  "@type": "Book",
  "name": "Gone with the Wind",
  "author": {
    "@type": "Person",
    "name": "Margaret Mitchell"
  },
  "workExample": [
    {
      "@type": "Book",
      "name": "Paperback of 'Gone with the Wind'",
      "bookFormat": "https://schema.org/Paperback"
    },
    {
      "@type": "Book",
      "name": "PDF of 'Gone with the Wind'",
      "bookFormat": "https://schema.org/EBook",
      "fileFormat": "application/pdf"
    },
    {
      "@type": "Book",
      "name": "EPUB of 'Gone with the Wind'",
      "bookFormat": "https://schema.org/EBook",
      "fileFormat": "application/epub+zip"
    }
