Programming Guide: Storage

# Programming Guide

# Storage

This chapter describes the external storage facilities OpenDoc uses and provides. OpenDoc relies upon the native file-storage facilities of each of the individual OpenDoc platforms. The same fundamental storage concepts and structures are used consistently for document storage and for data transfer (clipboard transfer, drag-and-drop, and linking, described in the next chapter).

Before reading this chapter, you should be familiar with the concepts presented in "Introduction" and "Development Overview". Additional concepts related to your part editor's run-time environment are found in "OpenDoc Run-Time Features".

This chapter introduces the general architecture of the OpenDoc storage system, including how parts are stored, and then describes how your OpenDoc part editor can use that architecture to store and retrieve its own content.
