<custom-meta> Custom Metadata

Wrapper element for a single piece of metadata not otherwise defined in the Tag Suite.

Usage/Remarks

This element can be used as an escape-hatch to record additional metadata that a publisher or archive wishes to preserve (so that the intellectual work to capture that content will not be lost) even though there is no direct expression for the metadata in the Tag Set.
The <custom-meta> element allows for an infinite variety of name/value pairs, with few constraints on the length or content of the value. This element will probably be used for special cases, product-specific material, or other unusual metadata, for example, the history of changes in the name of the book with different editions preserved in a publisher’s tag set.
Related Elements
The element <custom-meta-group> is a grouping element that holds one or more <custom-meta> elements. Each <custom-meta> element contains a name/value pair, <meta-name> and <meta-value> respectively, which name and provide a value for a single metadata field.
