This multi‐part International Standard defines a set of metadata keys and their meanings for use in PDF files to identify printed products and their component pages, to describe their appearance and characteristics and to guide their production.

The structure of the metadata is intended to encapsulate sufficient information in a PDF file to guide the production of printed products without the creator needing to know the details of the production processes that will be used.

The document part metadata conforming to this International Standard may be used to communicate the intended appearance of print products and their components. Example of intended use are: direct interpretation within a production process, creation of job tickets such as XJDF, or populating records in an MIS. This standard builds on the DPart syntax as specified in ISO 16612-1 (PDF/VT) and ISO 32000-2 (PDF 2.0) which is designed for encoding metadata related to pages or groups of pages in PDF files.

NOTE The document part metadata provided in this International Standard applies to individual document parts, whereas XMP metadata typically applies to the scope of the entire document. XMP can apply to the scope of an individual page or part of a page but this usage is very uncommon. Thus, XMP is not applicable for the case where metadata is required for sets of pages such as multiple recipients or binding information. For example, XMP is used within PDF/X for file conformance identification and is also used for additional file level information such as author.

This part of this International Standard defines a base conformance level that includes the syntax of the metadata framework and the semantics of a core set of metadata.
