<related-object> Related Object Information

Description of an object (for example, book, book chapter, figure, or table) related to the article content but published separately. May include a link to the related object.


For example, the related object might be a related book, a chapter in a book, a dataset, a spreadsheet, or a figure or graphic from another published source.
This element represents the link’s reference to its target in three parts:
  1. The source is the largest publishable unit (named in analogy to the <source> element used in citations). In the case of a reference to somewhere in a book, @source-id would represent the book as a whole, perhaps via its ISBN.
  2. The document is the part of the source that is typically delivered when a user follows the link in electronic form. For example, when linking into a book it may be desirable to transfer only the relevant chapter, section, or other structural unit. That unit would be specified on the @document-id, perhaps via its XML ID.
  3. The object is the location within the document of the precise destination of the link. For example, the object might be a particular list, paragraph, figure, table, subsection, or other element specified by its XML ID (and a viewing application might scroll to it). In scanned data, the object might be a page specified by number, or an area-to-highlight specified by co-ordinates. In a relational database, the object might be a specific row, selection, or view specified by a query.

Best Practice

For each source, document, and object, an identifier should be specified on the corresponding attribute. For any related-object link, the @source-id attribute points to the largest publishable unit, for example, an entire book. The @document-id attribute points to a major component of the source, for example, a chapter, front matter section (Preface), or back matter section (Appendix) of a book. Use the @object-id attribute to point to any item within the specified major document component, for example, a section, figure, table, or reference within the chapter of the book.
Where the more specific attributes are populated, the less specific attributes should also be populated. For example, if @object-id is specified, then both @document-id and @source-id should also be populated. If @source-id points to the intended target (an entire book), then neither @document-id nor @object-id should be specified.
The <related-object> element can also provide a name for the type of each identifier used, for example, ISBN, ISSN, DOI, XMLID, URI, and so on. These go on @source-id-type, @document-id-type, and @object-id-type as appropriate.
Finally, the <related-object> element can provide a name for the type of destination data each identifier actually points to, for example, Book, Part, Chapter, Section, Table, Glossary, Figure, Page, and so on. These go on @source-type, @document-type, and @object-type as appropriate. An application might, as one example, use @object-type values to display links to Figures in a different style than links to Chapters or Tables. When applicable, these types may, but need not, correspond to XML element type names.
Historical Note
This element (<related-object>) was new in the last NLM version (NLM 3.0) of this Tag Set, although some users had already added a custom element of the same name to prior versions. The values and/or usage in this NISO JATS version may not be backward-compatible with such customizations.

Book chapter and section
<p>From my personal experience, which is also informed by the 
 research findings reported in <related-object
   document-type="chapter">chapter four</related-object> (<related-object
   object-type="sec">section 4.3.3</related-object>), the belief that a 
 vegan diet can be nutritionally adequate is much disputed.</p>
Appendix and bibliographic citation
<p>[...] As the nutrition literature is complicated and may 
 distract from the moral argument in spite of its importance 
 for that very same moral argument, my narrow, nutritionally-based
 answer to the first question of importance in this book has
 been reserved for the book&#x02019;s <related-object 
   id="wt605845_app1_1" link-type="booklink"
 >appendix</related-object>, which provides a detailed overview 
 of the academic literature on vegan nutrition. A similar 
 appendix was provided in the first edition of
 <related-object id="wt605845_rl1_r520_1" 
 >Singer (1975)</related-object>&#x02019;s <italic>Animal 
 Liberation</italic>, but no longer featured in the second 
 edition due to his view that the &#x02018;nutritional 
 adequacy of a vegetarian diet is not in dispute.</p>
