==Format internals==
An OpenDocument file commonly consists of a standard [[ZIP (file format)|ZIP]] archive ([[JAR (file format)|JAR]] archive<ref>{{cite web |url=http://www-03.ibm.com/able/resources/odfintro.html |archive-url=https://web.archive.org/web/20080602152400/http://www-03.ibm.com/able/resources/odfintro.html |url-status=dead |archive-date=2008-06-02 |title=Web resources & interesting links - easy and simple introduction to OpenDocument Format (ODF) |accessdate=2010-06-07}}</ref>) containing a number of files and directories; but OpenDocument file can also consist only of a single XML document. An OpenDocument file is commonly a collection of several subdocuments within a (ZIP) ''package''. An OpenDocument file as a ''single XML'' is not widely used.
According to the OpenDocument 1.0 specification, the ZIP file specification is defined in ''Info-ZIP Application Note 970311, 1997''.<ref>{{cite web |url=http://tools.oasis-open.org/issues/browse/OFFICE-2205 |title=NEEDS-DISCUSSION: ZIP reference - N 1309 |accessdate=2010-06-07}}</ref><ref>{{cite web |url=http://tools.oasis-open.org/issues/browse/OFFICE-2082 |title= Zip reference is neither public nor authoritative |date=2009-10-11 |accessdate=2010-06-07}}</ref>
The simple compression mechanism used for a package normally makes OpenDocument files significantly smaller than equivalent Microsoft "<code>.doc</code>" or "<code>.ppt</code>" files. This smaller size is important for organizations who store a vast number of documents for long periods of time, and to those organizations who must exchange documents over low bandwidth connections. Once uncompressed, most data is contained in simple text-based XML files, so the uncompressed data contents have the typical ease of modification and processing of XML files. The standard also allows for the creation of a single XML document, which uses ''<office:document>'' as the root element, for use in document processing.
