What is ISO 21812-1- Architecture and core requirements for metadata for PDF files about?
ISO 21812 is an international standard on graphic technology that discusses print product metadata for PDF files.
ISO 21812-1 provides for architecture and core requirements for metadata for PDF files for printing PDF files to enhance the efficacy of print production.
ISO 21812-1 is the first part of a multi-part series that can be used to communicate the intended appearance of print products and their components.
ISO 21812-1 builds on the DPart syntax as specified in ISO 16612-2 (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.
ISO 21812-1 defines standardized metadata to:
- Provide product intent specifications such as paper media selection and binding information
- Identify the type of product that the content pages are intended to represent
- Identify the intended recipient of each of the content pages for variable document printing applications
ISO 21812-1 defines a base conformance level that includes the syntax of the metadata framework and the semantics of a core set of metadata.
Note: The document part metadata provided in ISO 21812-1 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.
Who is ISO 21812-1- Architecture and core requirements for metadata for PDF files for?
ISO 21812-1 on architecture and core requirements for metadata for PDF files is useful for:
- Printing device manufacturing companies
- Graphic designers
- Graphic designing company
- PDF creation vendors
Why should you use ISO 21812-1- Architecture and core requirements for metadata for PDF files?
PDF files represent content pages and do not normally contain information identifying the usage of these content pages in print production. Document part metadata is a simple mechanism that allows for the exchange of information regarding a set of content pages to aid the receiver of the PDF files in determining the intended use of those content pages in the final print product.
ISO 21812-1 provides you with 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 provided under ISO 21812-1 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 are used. With compliance and obedience to ISO 21812-1, you can effectively communicate with printing and finishing systems that can receive and act on the provided PDF content data.
