What is MIME type "application/xop+xml"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

application/xop+xml is a MIME type that supports the packaging of XML data with binary content. It uses an XOP technique to avoid encoding binary data in XML, which can boost performance.

This type is often used in web services to carry large binary attachments with XML messages. It helps to transfer files without increasing size by converting binary data into text.

• Efficient packaging of XML and binary data
• Often used with SOAP and MTOM in web services
• Removes the need for base64 encoding

Files with the XOP extension benefit from this technology. It makes data exchanges smoother on systems that work with complex XML structures.
