Structural Information

From a structural information perspective, there are two sets of data defined in this schema: core lists and sizes.

The schema first defines a number of lists that serve as the foundation for most objects in the presentation. These lists are as follows:

• Slide IDs

• Slide Masters

• Notes Masters

• Handout Masters

• Custom Shows

It is essential that the reader fully understand the implementation of usage of these lists as they are the foundation for almost all solutions that operate—open, interrogate, modify, write—against the PresentationML file format.

As mentioned above, the lists are defined as a part of list entry and list complex types. The slide master list is defined as follows:

<xsd:complexType name="CT_SlideMasterIdListEntry">
  <xsd:attribute ref="r:id" use="required" />
</xsd:complexType>
<xsd:complexType name="CT_SlideMasterIdList">
  <xsd:sequence>
    <xsd:element name="sldMasterId" type="CT_SlideMasterIdListEntry"
        minOccurs="0" maxOccurs="unbounded" />
  </xsd:sequence>
</xsd:complexType>

Although not complex or difficult to understand, the lists are called out because they are vital to any solution.

The next pieces of structural information are the sizes for the slides and the notes slides. By storing this information at the presentation level, the implication is that all slides (or all notes slides) in a presentation have the same size. This further implies that all slides in a presentation share the same orientation (i.e., they are all landscape-oriented or all portrait-oriented).
