Subject or type of content that makes this element semantically distinct.
The values for this attribute may include information classes, semantic categories, or functions for grouping elements. This attribute could identify: the name of a drug, company, or product; systematics terms such as genus, species, or family; or biological systems components, such as gene, protein, or peptide. The attribute could also be used to record that the content of a table cell is a total or subtotal amount, that a sidebar (<boxed-text>) contains a case study, or that a <statement> is a theorem or a proof.
Conversion Note: This attribute can be used to preserve semantic tagging that can’t be captured directly with an element in this Tag Set.
Display/Formatting Note: The presence of a @content-type attribute may be used to treat its element in a distinct way, for example, giving the work, phrase, or structure a different look in print or on display. This type of formatting may be guided by the value of the attribute, for example, making all circulatory system words (identified by a <named-content> element) red or putting a background image behind case studies.
Historical Note:In the redesign of this Tag Set that led to NISO JATS, a @content-type attribute was added to more than 60 elements because “type” attributes are viewed as a useful tool for preserving Publisher semantics without extending the Tag Set. The attribute was added according to the following rationale:
| Value | Meaning |
|---|---|
| Text, numbers, or special characters | Names/describes the distinct function for the <named-content> that cannot otherwise be described by the elements in this Suite. For example, a medical article might use the value “body-system” or “gene” while a management article might use the value “product-name” or “stock-code”. |
| Restriction: | |
| Value | Meaning |
|---|---|
| Text, numbers, or special characters | Names/describes any distinct semantics of the associated element. This may be used to preserve the semantic intent of prior tagging, for example, to record that a table cell was a total or subtotal amount. This may also be used to attach information classes to an element for retrieval purposes. |
