Schema/DTD of PowerPoint

Question

I am looking for a way to add some meta-infromation to PowerPoint files. Specifically, I want to add annotation to bullets and slides.

Are there any XML attributes which can be added to the elements (of the slideX.xml file) without invalidating it? In other words, where can I find the schema/DTD of the slideX.xml files?

Answer 1

"Best Practice" is to download the Open XML SDK 2.0 and use the tool DocumentReflector

Create the document you would like to have and then load that pptx into the DocumentReflector and check how to generate that code....

Annotations to slide is that Notes on the slide?!?! Then you need to create a NotesSlide http://msdn.microsoft.com/en-us/library/documentformat.openxml.presentation.notesslide(office.14).aspx

Answer 2

Yeah, you can use ExtLst and Ext which is basically adding your own extension to PresentationML, to "tag" just about anything at all in SlideX.xml. You can read more about it here.
