What is OOXML? Office Open XML, also known as OpenXML or OOXML, is an XML-based format for office documents, including word processing documents, spreadsheets, presentations, as well as charts, diagrams, shapes, and other graphical material.

Contains properties specific to an OOXML document--properties such as the template used, the number of pages and words, and the application name and version. File Properties, Core: Core file properties enable the user to discover and set common properties within a package--properties such as creator name, creation date, title.

The structure is organized according to the Open Packaging Conventions as outlined in Part 2 of the OOXML standard ECMA-376. You can look at the file structure and the files that comprise a PresentationML file by simply unzipping the .pptx file.

OOXML does not define pages--only paragraphs and text. However, it does enable the storing of certain information important to page composition, such as page size, page orientation, borders and margins. It does this through the use of the section.

Annex G of the ECMA-376, 3rd Edition (June, 2011) OOXML specification defines built-in styles for cells, tables, and pivot tables, and style TableStyleMedium9 is among the built-in table styles. The built-in table and pivot table styles are not stored in the styles part--only custom styles are.

The content model for text in ODF is very similar to HTML. Character data is inside of paragraphs without being further nested in runs and text elements as it is in OOXML. When formatting of text within a paragraph is necessary, the <text:span> element is used.
