Contents. DefinitionQuoted from the IDPF web site:'.epub' is the file extension of an format for reflowable digital books and publications. '.epub' is composed of three open standards, the Open Publication Structure , Open Packaging Format and Open Container Format , produced by the IDPF.
'.epub' allows publishers to produce and send a single digital publication file through distribution and offers consumers interoperability between software/hardware for unencrypted reflowable digital books and other publications. The Open eBook Publication Structure or ', originally produced in 1999, is the precursor to OPS.' UsageThe intent of ePub is to serve both as a source file format and an end user format. For this reason the files are collected into a container for easy dissemination and use. This container is generally a zip file but the extension has been renamed to.epub. It has special build requirements by including an uncompressed mime type file as the first entry in the container.
The rest of the data in the file should be compressed. An ePub reader should be capable of reading the content in its compressed format.Mime Type: Multipurpose Internet Mail Extensions.
“ MIME media types” provide a standard methodology for specifying the content type of objects. Specificationscontains the specifications for this format.
In particular check the version 2.01 OPS and OPF specifications and the version 1.01 OCF specifications. The informational documents are also quite useful in understanding the standard's intent and content. Note that the idpf references are an archive of the site. The active site is now OCFOCF stands for Open Container Format. A typical OCF is a zip file that might look like:mimetypeMETA-INF/container.xmlmanifest.xmlmetadata.xmlsignatures.xmlencryption.xmlrights.xmlOEBPS/Great Expectations.opfcover.htmlchapters/chapter01.htmlchapter02.html other HTML files for the remaining chapters images/cover.jpg mimetypeThe first file in the Container MUST be a file by the ASCII name of ‘mimetype’ which holds the MIME type for the ZIP Container (i.e., “application/epub+zip” as a 20 character ASCII string; no padding, no CR/LF, no white-space or no case change). The file MUST NOT be compressed nor encrypted and there MUST NOT be an extra field in its ZIP header.
The idea is to allow a program like the Unix file command to identify the content without unzipping the file. To do this in Zip you make the zip file containing the mimetype first by itself and then add the additional files later. container.xmlThe container.xml is a required file with a required name. It must be in the META-INF folder.
All other folders are optional and can be any name the user chooses. The container.xml file shows the filename and location of the OPF file. OPFThe Open Packaging Format Specification, defines the mechanism by which the various components of an OPS publication are tied together and provides additional structure and semantics to the electronic publication.Specifically, OPF:. Describes and references all components of the electronic publication (e.g. Markup files, images, navigation structures). Provides publication-level. Specifically it should include:.
See for specific capabilities for ePub metadata. Specifies the linear reading-order of the publication.

The unique Identifier (DOI, ISBN, JDCN, or UUID as listed ). Date is not required but encouraged, an event attribute can be used to refine the purpose of the date. Unique IDA unique id is a required element in the OPF.
Here is one way to accomplish this. Just click on the site and it will give you an id:.
There is an attribute scheme to identify the source or authority. (shown in the example above). Another UUID generating site isWhen using a UUID your identifier line should look like this.
