Persistence and interoperability are two vitally important features, especially for applications that use ink. To enable persistence and interoperability of ink, an application must allow users to:

• Save and open their documents with full fidelity of ink data.
• Move data to and from other Microsoft® Windows®-based applications by using the Clipboard.

The following sections detail ink interoperability.

• Ink Data Formats
• Important Interoperability Scenarios
• Persistence Formats
• Choosing Which Formats to Support
• Building Blocks
• Storing Ink in HTML

This document assumes a detailed understanding of the Clipboard. For more information about the Clipboard, see the Clipboard documentation of the MSDN® Library.
