Runnable versions of every example live in the GitHub examples repository.

• Loading files — load from disk, a stream, a specific format, or a password-protected document.
• Saving files — save to a path, a stream, or back to the original source.
• Working with metadata properties — extract property values and export the metadata tree.
• Working with metadata standards — read and edit EXIF, IPTC IIM, and XMP metadata.
• Extracting metadata — search by tags and categories.
• Adding metadata — add known-but-missing properties.
• Removing metadata — remove properties by category or other criteria.
• Getting known property descriptors — inspect the properties a package supports.
• Working with interpreted values — read human-readable values for numeric/enum properties.
