Chapter 10. Document Interchange

Chapter 10. Document Interchange

The features described in this chapter do not affect the final appearance of a document. Rather, these features enable a document to include higher-level information that is useful for the interchange of documents among applications:

  • Procedure sets (Section 10.1) that define the implementation of PDF operators

  • Metadata (Section 10.2) consisting of general information about a document or a component of a document, such as its title, author, and creation and modification dates

  • File identifiers (Section 10.3) for reliable reference from one PDF file to another

  • Page-piece dictionaries (Section 10.4) allowing an application to embed private data in a PDF document for its own use

  • Marked-content operators (Section 10.5) for identifying portions of a content stream and associating them with additional properties or externally specified objects

  • Logical structure facilities (Section 10.6) for imposing a hierarchical organization on the content of a document

  • Tagged PDF (Section 10.7), a set of conventions for using the marked content and logical structure facilities to facilitate the extraction and reuse of a document's content for other purposes

  • Various ways of increasing the accessibility of a document to users with disabilities (Section 10.8), including the identification of the natural language in which it is written (such as English or Spanish) for the benefit of a text-to-speech engine

  • The Web Capture plug-in extension (Section 10.9), which creates PDF files from Internet-based or locally resident HTML, PDF, GIF, JPEG, and ASCII text files

  • Facilities supporting prepress production workflows (Section 10.10), such as the specification of page boundaries and the generation of printer's marks, color separations, output intents, traps, and low-resolution proxies for high-resolution images
