Network Working Group G. Conboy Request for Comments: 4839 J. Rivlin Category: Informational eBook Technologies, Inc. J. Ferraiolo IBM April 2007 Media Type Registrations for the Open eBook Publication Structure (OEBPS) Package File (OPF) Status of This Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The IETF Trust (2007). Abstract This document serves to register a media type for the Open eBook Publication Structure (OEBPS) Package Files. 1. 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. 2. 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. Conboy, et al. Informational [Page 1]
RFC 4839 Media Type Registrations for OPF April 2007 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. 3. 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]. 3.1. Media Type for Downloadable Sounds Type name: application Subtype name: oebps-package+xml Required parameters: none Optional parameters: none Encoding considerations: OPF files are UTF-8 or UTF-16 encoded XML Security considerations: none Interoperability considerations: none Published specification: Specification is published by the International Digital Publishing Forum and can be found at http://www.idpf.org/oebps/ oebps1.2/download/oeb12-xhtml.htm Applications which use this media type: 1) eBook Technologies, Inc. eBook reading system. 2) Microsoft Reader 3) OSoft reader 4) Content Reserve Publishing System 5) IDPF Container WG 6) PC Reader.com 7) MobiPocket reader Conboy, et al.
