Package Structure

A PresentationML package shall contain a package-relationship item and a content-type item. The package-relationship item shall contain implicit relationships with targets of the following type:

  • One Presentation part (§13.3.6).

The package-relationship item is permitted to contain implicit relationships with targets of the following type:

  • Digital Signature Origin (§15.2.6)

  • File Property parts (§15.2.11) (Application-Defined File Properties, Core File Properties, and Custom File Properties), as appropriate.

  • Thumbnail (§15.2.14).

The required and optional relationships between parts are defined in §13.3 and its subordinate clauses.

example:

First, the content type for relationship parts and the Main Presentation part (the only required part) must be defined (physically located at /[Content_Types].xml in the package):

<Types xmlns="…">
  <Default Extension="rels"
    ContentType="application/vnd.openxmlformats-
      package.relationships+xml"/>
  <Override PartName="/presentation.xml" 
    ContentType="application/vnd.openxmlformats-
      officedocument.presentationml.presentation.main+xml"/>
</Types>

Next, the single required relationship (the package-level relationship to the Main Presentation part) must be defined (physically located at /_rels/.rels in the package):

<Relationships xmlns="…">
  <Relationship Id="rId1" 
    Type="http://schemas.openxmlformats.org/officeDocument/2006/
      relationships/officeDocument"
    Target="presentation.xml"/>
</Relationships>

Finally, the minimum content for the Main Presentation part must be defined (physically located at /presentation.xml in the package):

<p:presentation xmlns:p="…">
  <p:notesSz cx="913607" cy="913607"/>
</p:presentation>
