A class representing the basic document metadata provided in a PDF File.
This class is accessible through
:py:class:`PdfReader.metadata`.
All text properties of the document metadata have
*two* properties, e.g. author and author_raw. The non-raw property will
always return a ``TextStringObject``, making it ideal for a case where the
metadata is being displayed. The raw property can sometimes return a
``ByteStringObject``, if pypdf was unable to decode the string's text
encoding; this requires additional safety in the caller and therefore is not
as commonly accessed.

It is an array of dictionaries with "/F" (the first bead in the thread)
and "/I" (a thread information dictionary containing information about
the thread, such as its title, author, and creation date) properties or
None if there are no articles.
Since PDF 2.0 it can also contain an indirect reference to a metadata

Property that emulates a list of :class:`PageObject`.
This property allows to get a page or a range of pages.
Note:
For PdfWriter only: Provides the capability to remove a page/range of
page from the list (using the del operator). Remember: Only the page
entry is removed, as the objects beneath can be used elsewhere. A
solution to completely remove them - if they are not used anywhere - is
to write to a buffer/temporary file and then load it into a new
PdfWriter.
