Related content

Capture a link to a related item using a related-object element.

//book-meta/related-object
//book-part-meta/related-object

Use an empty related-object element within book-meta or book-part-meta for a link provided as a supplement to the content.

The use of attributes of related-object (for links to other OUP books and chapters) is the same as for links provided within the content. (See Cross-references.) Capture the DOI of the target as the value of the object-id attribute (if the target is not a book) or the document-id attribute (if the target is a book).

For external related items (i.e. URLs and not DOIs of OUP content), capture the following attributes on the related-object element.

Attributes of related-object when target is external

Attribute name	Value
document-type	url
source-id	URL of the related item
source-type	The type of the target. Allowed values are: blog-article companion-website external-resource quiz video
source-id-type	url

Link from part of a book to the parent book

For each chapter, section of front or back matter, and appendix of a book, capture a related-object element with attribute link-type="isPartOf", and include the book's ISBN as the value of the document-id attribute. For books with multiple ISBNs, use the following priority order:

electronic
ebook-updf
ebook-epub
print
print-paperback
