TF JATS Version Numbering

Version numbers are assigned to versions of the TF JATS schema independently of NISO JATS' version numbering. The NISO JATS version that TF JATS imports is referenced in documentation and in the DTD public identifier of TF JATS. TF JATS version numbers are assigned using the numeric major.minor convention.

The schema-version attribute must be present on the root element (<article> or <issue-manifest>) of all TF-JATS XML. The value is enforced by the DTD and the XML Schema, and indicates the TF JATS schema version used to create the XML file. The value of the schema-version attribute can guide validation and other processing.

The major and minor version numbers are included in the system identifier (URL path) of the TF JATS schema files. The major version number is included in the main files of the TF JATS schema. For example: http://cats.informa.com/tfjats/1.0/xsd/tfjats1.xsd. The major and minor version numbers are also included in the DTD public identifier.
