Repurposing Adobe PDF
Documents
With Acrobat, you can easily repurpose the contents of your documents using structured
or tagged Adobe PDF files.Tagged Adobe PDF files in particular allow you to save your
document's contents to other formats such as RTF with better results, reflow your
document's contents into different-sized devices such as eBook reading devices, and
make your document's contents accessible to the motion and vision challenged through
the use of a screen reader for Windows.You can create tagged Adobe PDF files automati-
cally when you use Acrobat to convert Web pages to Adobe PDF, or you can do so when
you use Acrobat PDFMaker 5.0 to create Adobe PDF files from within Microsoft Office 2000
for Windows applications.
About the different types of Adobe PDF documents
There are three types of Adobe PDF documents: unstructured, structured, and tagged.
These document types differ in what they contain and how their contents can be repur-
posed. In general, the more structural information the Adobe PDF document contains, the
more options you have for repurposing its contents.
If you're already familiar with the different types of Adobe PDF documents and need infor-
mation on how to create them, see

Contents of different types of Adobe PDF documents
To understand the different types of Adobe PDF documents, it's important to first under-
stand their differences in content. Unstructured Adobe PDF documents can contain
several forms of content:
The author's content, including pages, articles, paragraphs, tables, and figures.
•
Comments such as online notes, graphic markups, and text markups.
•
Pagination artifacts such as page numbers and running headers.
•
Layout and typographic artifacts such as colored bars between columns of text and
•
horizontal lines separating footnotes from text.
Printing artifacts such as crop marks, printer's stars, and the document name printed
•
outside of the crop marks.
In addition to this content, structured and tagged Adobe PDF documents contain infor-
mation that provides you with more options for repurposing their contents. Structured
and tagged Adobe PDF documents both contain a logical structure tree that references
the author's content in a natural reading order. Comments and artifacts aren't referenced
by the logical structure tree, because they're not considered useful when repurposing the
document's contents. For example, when a document's contents are read by a screen
reader, the document's page numbers aren't considered useful information for users.
