content-type

Type of Content

Definition

Identifies a subject or type of content that makes this element semantically special

Usage

This attribute can be used to name or describe a special function for an associated element, for example, to record that the content of a table cell is a total or subtotal amount, that a side bar (element <boxed-text>) contains a case study, or that a <statement> element’s content is a theorem.

Remarks

This attribute could identify a drug name, company name, or product name. It could also be used to define systematics terms, such as genus, family, order, or suborder. Similarly, it could be used to identify biological components, such as gene, protein, or peptide. Therefore, the values may include information classes, semantic categories, or types of nouns such as “generic-drug-name”, “genus-species”, “gene”, “peptide”, “product”, etc.

The presence of a content-type attribute may be used to treat its element in a special 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, putting a background image behind case studies.

Design Note: In version 2.3, because “type” attributes were viewed as a useful tool for preserving Publisher semantics without extending the tag set, content-type attributes were added to more than 60 elements according to the following rationale.

Attribute Values

In Element

<named-content> Named Special (Subject) Content
Value Meaning
Text, numbers, or special characters Names/describes the special function for the <named-content> that cannot otherwise be described by the elements in this tag set. 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: This attribute must be specified if the element is used.

Value Meaning
Text, numbers, or special characters Names/describes any special 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: This attribute may be specified if the element is used.
