Product Information

Container element for the metadata concerning one product (for example, a book, software package, website, or hardware component) discussed in an article.


Related Essay: One major use for this element is to hold the metadata about a product that is being reviewed. For a discussion on the use of <product> in Reviews, see Tagging Book or Product Reviews.

Best Practice: This element should be used when the value of the @article-type attribute on the element <article> is “book-review” or “product-review”.

A review of a book, journal, website, etc., should include as much information about the item being reviewed as is practical, for example, the running time of a film or the number of pages in a book (both of which would be tagged as <size>). See the tagged example below for more element uses.

Historical Note: This element (<product>) was significantly remodeled from previous versions of this Tag Set. The current NISO JATS values are backwards compatible with the last NLM version, but not with earlier versions. Specifically, in prior versions the <product> element was allowed to contain the <page-count> element, now replaced by the <size> element.
