Overview
ISO/IEC 26300:2006/Cor 2:2011 is Technical Corrigendum 2 to the Open Document Format (ODF) v1.0 international standard (ISO/IEC 26300:2006). Published 2011-12-01 and prepared by ISO/IEC JTC 1/SC 34, this corrigendum supplies clarifications, corrections and editorial changes equivalent to Part 2 of the OASIS ODF v1.0 errata. It is intended to be read after ISO/IEC 26300:2006 and Technical Corrigendum 1. Some OASIS Errata changes were intentionally omitted where they conflict with later ODF 1.1 work.
Key topics and technical clarifications
The corrigendum focuses on precise behavior and semantics across ODF XML vocabularies, including:
- Whitespace processing: Requires conformance with XML 1.0 and instructs processors to ignore element children that are whitespace-only strings when they don’t match schema patterns.
- Version and validation: Removes ambiguous language about optional validation based on a file’s declared version.
- Language tags: Replaces descriptive text with a direct reference - syntax/semantics follow RFC3066.
- Security-related text: Notes that password hashing (for protected sections and tables) is implementation-dependent; hashed values are stored instead of plain passwords.
- Attributes and element semantics: Multiple attribute definitions and defaults are clarified or corrected (examples include text:fixed, text:index-scope, text:use-caption, text:copy-outline-levels, table:visibility, and renaming or clarification of attributes such as table:protect and office:value-type).
- Spreadsheet and indexing behavior: Clarifies detection/highlighting operations, filter/search semantics, data pilot descriptions, cell value-type conditions, and that many spreadsheet functions and regular-expression syntaxes are implementation-dependent.
- Graphics and shapes: Rewords shape/connector definitions to clarify start/end points and allowed anchors.
- Editorial corrections: Small text fixes (e.g., “drawing” → “draw”), corrected counts (seven index types), and schema-related wording adjustments.
Applications and who uses it
This corrigendum is important for:
- Office suite developers implementing or updating ODF support in writers, spreadsheets, presentations.
- ODF parser and validator implementers who need unambiguous element/attribute semantics.
- Interoperability testers and QA teams ensuring consistent behavior across applications.
- Government, archival and enterprise IT teams that rely on stable, standardized document formats for long-term preservation and data exchange.
- Standards bodies and ODF tool vendors aligning implementations with international corrections.
