Type of Content

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 word, 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.

Used on Element: <named-content>

Text, numbers, or special charactersNames/describes the distinct function for the <named-content> that cannot otherwise be described by the elements in this Suite. For example, a chapter in a medical book might use the value “body-system” or “gene” while a chapter in a management book might use the value “product-name” or “stock-code”.
Restriction@content-type is required; it must be provided if the element is used.

Text, numbers, or special charactersNames/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.
Restriction@content-type is an optional attribute; there is no default.

Example 1

Used as part of <named-content> to record metadata for which JATS has no metadata elements:
<named-content content-type="program">Joint United
Nations Program on HIV/AIDS (UNAIDS)</named-content>,
<institution>World Health Organization</institution>,
Geneva, <country>Switzerland</country>

Example 2

To describe the role of each of the <compound-kwd-part>s:
<kwd-group kwd-group-type="Inspec-class">
<compound-kwd-part content-type="code">B0260</compound-kwd-part>
<compound-kwd-part content-type="text">Optimisation
