<custom-meta>
Custom Metadata
Wrapper element for a single piece of metadata not otherwise defined in the Tag
Suite.
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.
