ISO ISO IEC TS 22424-2-2020 pdf free download – Digital publishing — EPUB3 preservation — Part 2: Metadata requirements.
The ISO/IECTS 22424 series supports long-term preservation of EPUB publications via a dual strategy.This document makes EPUB compliant with current practices of Open Archival Information Systems(OAIS) archives and technical requirements of repository systems. The former tend to rely on OAISin their operations; the latter prefer to ingest electronic documents only in containers conforming tostandards such as METS (Metadata Encoding and Transmission Standard).
ISO/IECTS 22424-1 considers EPUB features from a long-term preservation point of view.

3.1 data dictionary
organized and constructed (electronic data base) compilation of descriptions of data conceptsthat provides a consistent means for documenting,storing and retrieving the syntactical form (i.e,representational form) and the meaning and connotation of each data concept
Note 1 to entry: PREMIS is a data dictionary.PREMIS Data Dictionary for Preservation Metadata (https:;/www,.loc.gov/standards/premis) is a leading metadata specification for metadata needed for long-term preservation,[SOURCE: ISO 24531:2013,4.14, modified —Note 1 to entry has been added.J
3.2 structural metadata
metadata that indicates how compound objects are put together, for example how the pages of a document are arranged to form chapters

5 Syntax
This document provides examples of how metadata elements should be expressed using either
1) Metadata Encoding and Transmission Standard (METS5) version 1.12.1 and PREMIS Data
Dictionary for Preservation Metadata (PREMIS6)) version 3.0, and/or
2) EPUB version 3.0 and 3.0.1
for encoding SIPs.Other container standards may be added to the future editions of this document.This dual approach was chosen because there are different options available for a producer to turnexisting EPUB publications into SIPs:
1) All metadata (mandatory and otherwise) may be embedded in the EPUB publication.
2) Mandatory metadata is copied from EPUB document to the METS container if and when it is already
present, or created and placed in the METS container (recommended approach).
3) Option 2, but a container standard other than METS is used.
The first option looks appealing because that way it would be relatively easy to createEPUB publicationssuitable for long-term preservation, especially if the mandatory metadata elements are already present(and if the EPUB publication itself does not have features unsuitable for preservation).
Unfortunately this approach has some issues:
– Commonly used repository systems expect information packages based on container standards
such as METS.Current versions of these applications may not able to process SIPs which containonly an EPUB publication.
Depending on the mandatory metadata required, it may not be possible to include all preservationmetadata into EPUB publication.ISO ISO IEC TS 22424-2 pdf download.
