be reasonably legible to humans: <text:h style-name="Heading_2">This is a title</text:h> <text:p style-name="Text_body"/> <text:p style-name="Text_body"> This is a paragraph. The formatting information is in the Text_body style. The empty text:p tag above is a blank paragraph (an empty line). </text:p> styles.xml styles.xml contains style information. OpenDocument makes heavy use of styles for formatting and layout. Most of the style information is here (though some is in content.xml). Styles types include: Paragraph styles Page styles Character styles Frame styles List styles The OpenDocument format is somewhat unusual in that using styles for formatting cannot be avoided. Even "manual" formatting is implemented through styles (the application dynamically makes new styles as needed). meta.xml meta.xml contains the file metadata. For example, Author, "Last modified by", date of last modification, etc. The contents look somewhat like this: <meta:creation-date>2003-09-10T15:31:11</meta:creation-date> <dc:creator>Daniel Carrera</dc:creator> <dc:date>2005-06-29T22:02:06</dc:date> <dc:language>es-ES</dc:language> <meta:document-statistic table-count="6" object-count="0" page-count="59" paragraph-count="676" image-count="2" word-count="16701" character-count="98757"/> The names of the <dc:...> tags come from the Dublin Core XML standard. settings.xml settings.xml includes settings such as the zoom factor or the cursor position. These are properties that are not content or layout. mimetype (file) mimetype is just a one-line file with the mimetype of the document. One implication of this is that the file extension is actually immaterial to the format. The file extension is only there for the benefit of the user. It is important to note that this special file is always the first file entry in the ZIP archive and it is uncompressed. Because the ZIP header uses fields with fixed lengths, this allows the direct identification of the different OpenDocument formats without decompression of the content (e. g. with magic bytes). Thumbnails (directory) Thumbnails is a separate folder for a document thumbnail. The thumbnail must be saved as “thumbnail.png”. A thumbnail representation of a document should be generated by default when the file is saved. It should be a representation of the first page, first sheet, etc. of the document. The required size for the thumbnails is 128x128 pixel. In order to conform to the Thumbnail Managing Standard (TMS) at www.freedesktop.org, thumbnails must be saved as 8bit, non-interlaced PNG image with full alpha transparency. META-INF (directory) META-INF is a separate folder. Information about the files contained in the OpenDocument package is stored in an XML file called the manifest file. The manifest file is always stored at the pathname META-INF/manifest.xml. The main pieces of information stored in the
