<extended-by> Extended-by Model

Identification of a JATS extension that the document claims to be following.

Usage/Remarks

The <extended-by> element names a JATS extension or superset that the document claims to be following. The content of <extended-by> may be a name, such as “taxpub”, or a URI. The element is repeatable so that more than one extension can be claimed.
Processing Metadata
The element <processing-meta> provides a more complete in-the-XML description of the tag set associated with a document than can be understood by the article content elements alone. A <processing-meta> names (through attributes) the tag set, table model, and MathML options a document follows and (through elements) some of the modeling restrictions or extensions the document claims to follow.
Processing Metadata is not considered to be part of the content of an article, or part of the metadata for citing an article; it is metadata about how the XML is constructed — not about how the article is structured. This metadata is information at the “file level” and thus not part of <article-meta>, but inside the article as a peer to <front>, which is the article and journal metadata container in JATS.
  • New processing metadata container element (<processing-meta>) was added to the model of <article> as a child element, the peer of <front>.
  • The elements inside <processing-meta> name tag set extensions (superset) and restrictions (subset, secondary schema, etc.) that the XML document claims to follow.
  • The attributes on <processing-meta> describe the modeling choices made by this document in terms of tag set family, base tag set, table model, and math tagging.

<processing-meta>

This optional container element is used to hold the processing metadata elements, which describe processing information descriptive of the XML-tagged document (document instance). The <processing-meta> element contains the following elements:
  • <restricted-by> — Identification of one of the guidelines or other restrictions (such as a tighter subset schema) the document claims to be following. The content of <restricted-by> may be a name such as “jats4r” or “pmc”, or a URI, for example, the URL of a particular JATS4R recommendation. The element is repeatable so that multiple restrictions can be claimed.
  • <extended-by> — Identification of a JATS extension or superset that the document claims to be following. The content of <extended-by> may be a name, such as “taxpub”, or a URI. The element is repeatable so that more than one extension can be claimed.
  • <custom-meta-group> — To hold other processing metadata a JATS user might want to express in the XML file.
