Overview
ISO/IEC 26300:2006/Amd 1:2012 amends the Open Document Format (ODF) v1.0 to produce OpenDocument v1.1. Published jointly by ISO and IEC (ISO/IEC JTC 1/SC 34), this amendment updates the normative Relax‑NG schema, clarifies conformance and processing rules, and adds features to improve pagination, accessibility conversion and document interchange. The Amendment is intended to be read together with ISO/IEC 26300:2006 and the associated technical corrigenda.
Key topics and technical changes
- OpenDocument / ODF v1.1: Formalizes the OASIS OpenDocument v1.1 content as an ISO/IEC amendment, preserving the XML‑based office file model.
- Relax‑NG schema updates: Normative schema fragments are amended (line inserts and reordering) to reflect new patterns and attributes required for ODF v1.1 conformance.
- Soft page breaks:
- New attribute text:use-soft-page-breaks (default false) at the document level to indicate presence of soft page breaks.
- New element **** to mark computed page breaks generated by layout engines.
- Rules for handling soft page breaks in tables, text boxes and during import/export; guidance for applications that do not support pagination.
- Change tracking and editing: Additions and editorial clarifications to change‑tracking behaviour and deletion handling (how to treat deleted paragraphs, headings and nested structures).
- List and content models: List items and text content models updated to allow soft page breaks within lists and to clarify root element content models.
- Metadata and document statistics: Schema changes to meta elements (e.g., object-count) for improved document statistics reporting.
- Conformance guidance: Clarifies that applications should not use foreign elements/attributes for features already defined in the OpenDocument schema.
Practical applications and users
- Software vendors and developers implementing ODF/OpenDocument readers/writers and office suites.
- Document conversion and accessibility toolchains (e.g., DAISY conversions) that benefit from explicit soft page break information.
- Archival and records management professionals requiring open, standardized office formats for long‑term preservation and interoperability.
- Government and enterprise IT teams adopting open formats for document interchange and vendor neutrality.
- XML schema and document-processing tool developers using the Relax‑NG schema to validate ODF files.
