The XMP Specification (Part 3) defines how to embed XMP in some popular file formats.

• In a TIFF file, tag 700 is used.
• In a JPEG file, an APP1 segment with identifier "http://ns.adobe.com/xap/1.0/" is used. Sometimes there are also APP1 segments with identifier "http://ns.adobe.com/xmp/extension/".
• In a PNG file, an iTXt chunk with keyword "XML:com.adobe.xmp" is used.
• In a JPEG 2000 file, XMP is stored in a "uuid" box with a particular ID. Apparently, it may also be stored in an "xml " box.
