Overview
ISO/IEC 26300-1:2015 specifies the OpenDocument v1.2 OpenDocument Schema - the XML schema and semantic rules for office documents used by OpenDocument (ODF). Part 1 of the OpenDocument v1.2 specification defines the document structure, declared XML namespaces, a Relax NG schema, and a metadata manifest ontology so that documents (text, spreadsheets, charts, drawings, presentations and other office content) can be validated, transformed with XSLT and processed with XML-based tools.
Key technical topics and requirements
- XML schema and validation: A formal Relax NG schema defines element and attribute models for OpenDocument v1.2; documents conformant to the schema are suitable for automated processing and validation.
- Document model and structure: Defines core elements such as , , , , , , and metadata containers to standardize representation of office content.
- Declared namespaces: Part 1 lists the ODF XML namespaces used across document types (e.g., office, text, table, drawing, chart, style, meta, manifest, presentation and others) enabling consistent XML parsing and interoperability.
- Metadata and manifest ontology: Specifies a metadata manifest ontology and namespace usage to support document metadata, discovery and lifecycle management.
- Transformability and toolchain compatibility: Documents valid to the schema are explicitly designed to be transformable via XSLT and processed by XML toolchains, aiding conversions, rendering and automated workflows.
- Interoperability provisions: Requirements for producers and consumers (applications that generate or consume OpenDocument files) to ensure consistent rendering and semantic fidelity.
Practical applications and who uses this standard
ISO/IEC 26300-1:2015 is essential for:
- Office application developers implementing ODF support (export/import, native formats).
- Document management and ECM vendors ensuring validated storage, search and processing of office documents.
- Government and enterprise IT seeking open, vendor-neutral formats for long-term preservation and policy compliance.
- Archivists and digital preservation teams who require standardized metadata and schema for reliable long-term access.
- Integration and conversion tool providers using XSLT and XML processing to convert, migrate or render documents.
- QA and interoperability testers validating conformity to ODF v1.2 schema.

- The specification is aligned with the OASIS OpenDocument TC outputs and includes links to authoritative ODF v1.2 part documents and schemas.
By standardizing the OpenDocument XML schema, ISO/IEC 26300-1:2015 enables robust interoperability, validation and automated processing of office documents across platforms and toolchains.
