The OASIS Technical Committee has approved the OpenDocument 1.3 specification.

Technical Committee of the OASIS Consortium approved the final version of the ODF 1.3 (OpenDocument) specification. After approval by the Technical Committee, the ODF 1.3 specification received the status of 'Committee Specification', which implies complete completion of work, future immutability of the specification, and readiness of the document for use by third-party developers and companies. The next step will be the approval of the presented specification as an OASIS and ISO/IEC standard.

The key differences of OpenDocument 1.3 from the previous version of the specification included the introduction of new features for document protection, such as document notarization with a digital signature and content encryption using OpenPGP keys. The new version also includes clarifications of wording and expands some already available features, for example:

• Support for polynomial types and moving averages regression for charts;
• Additional methods for formatting numbers have been implemented;
• A separate type of header and footer for the title page has been added;
• Tools for setting paragraph indents based on context have been defined;
• Additional arguments for the WEEKDAY function have been proposed;
• A new type of template for main text in documents has been added.

ODF is an XML-based file format independent of applications and platforms, designed to store documents containing text, spreadsheets, diagrams, and graphical elements. The specifications also include requirements for reading, writing, and processing such documents in applications. The ODF standard is applicable for creating, editing, viewing, exchanging, and archiving documents that can be text documents, presentations, spreadsheets, raster graphics, vector drawings, diagrams, and other types of content.

The specifications consist of four parts:

• Part 1, describes the general scheme of ODF;
• Part 2, describes the OpenFormula specification (formulas for spreadsheets);
• Part 3, describes the data packaging model in the ODF container.
• Part 4, defines the format for describing OpenFormula formulas
