Source-derived summary

The Office Open XML file formats, also known as OOXML, were standardised between December 2006 and November 2008, first by the Ecma International consortium (where they became ECMA-376), and subsequently, after a contentious standardization process, by the ISO/IEC's Joint Technical Committee 1 (where they became ISO/IEC 29500:2008).

Standardization within Ecma International

More than a year after being asked by the European Union to standardize their Office 2003 XML formats, Microsoft submitted 2,000 pages of documentation for a new file format to the Ecma International consortium for it to be made into an open standard. Ecma formed a technical committee (TC45) in December 2005, in order to produce and maintain a "formal standard for office productivity applications that is fully compatible with the Office Open XML Formats, submitted by Microsoft". The technical committee was chaired by two Microsoft employees and included members drawn from Apple, Canon, Intel, NextPage, Novell, Pioneer, Statoil ASA, Toshiba, The United States Library of Congress, The British Library and the Gnome Foundation.

During standardisation within Ecma the specification grew to approximately 6,000 pages. It was approved as an Ecma standard (ECMA-376) on December 7, 2006. The standard can be downloaded from Ecma free of charge.

International standardization

Using their entitlement as an ISO/IEC JTC 1 external Category A liaison, Ecma International submitted ECMA-376 to the JTC 1 fast track standardization process. To meet the requirements of this process,

they submitted the documents "Explanatory report on Office Open XML Standard (Ecma-376) submitted to JTC 1 for fast-track" and "Licensing conditions that Microsoft offers for Office Open XML". ISO and IEC classified the specification as DIS 29500 (Draft International Standard 29500) Information technology – Office Open XML file formats.

Editorial summary

This brief starts where responsible research should: with the source description of “Standardization of Office Open XML” as open-knowledge reference entry. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—2006, 2008, 2003, 2005—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Standardization, Office and Open-knowledge can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as open-knowledge reference entry. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jan 9, 2026. The linked authority identifier is Q7598397. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2006, 2008, 2003 and 2005.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
