Abstract
This document serves to register a media type for the Open eBook Publication Structure (OEBPS) Package Files.
Contents
Introduction
The present document registers a media type for the Open eBook Publication Structure (OEBPS) Package File (OPF). The OPF file is an XML file that describes an OEBPS Publication [OEBPS]. It identifies all other files in the publication and provides descriptive information about them. OPF and its related standards are maintained and defined by the International Digital Publishing Forum (IDPF).
The media type defined here is needed to correctly identify OPF files when they are edited on disk, referenced in OEBPS Container files, or used in other places where media types are used.
Security Considerations
The OPF files contain well-formed XML conforming to the XML 1.0 specification.
Clearly, it is possible to author malicious files which, for example, contain malformed data. Most XML parsers protect themselves from such attacks by rigorously enforcing conformance.
All processors that read OPF files should rigorously check the size and validity of data retrieved.
There is no current provision in the OEBPS Package File standard for encryption, signing, or authentication within the file format.
IANA Considerations
IANA has registered the media type application/oebps-package+xml as specified in Section 3.1. The registration uses the template present in RFC4288.
