Each page is defined as an independent entity with metadata (e.g., page dimensions) and a reference to its resources and content, which are defined separately. Together, the page tree and page objects create the “paper” that composes the document.

Resources are objects that are required to render a page. For example, a single font is typically used across several pages, so storing the font information in an external resource is much more efficient. A content object defines the text and graphics that actually show up on the page. Together, content objects and resources define the appearance of an individual page.

Finally, the document’s catalog tells applications where to start reading the document. Often, this is just a pointer to the root page tree.";
