Rich PDF is a PDF document which can be opened and read in a regular PDF reader but which also has two other documents embedded within it: A copy of the original document and an XML version, so that the Rich PDF document can be shared with confidence that it will be readable by any PDF reader but that it will also provide richer interactions for those readers who can access the additional rich-formats.
- PDF readable output which can be accessed through any legacy PDF reader software
- A compressed and embedded copy of the original document which the original software can open and retain full interactivity (with the author’s ability to restrict output)
- An XML version of the original which can be used by Rich PDF aware applications to make more useful interactive information available.
- An ePub version.
