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

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

application/lost+xml is a MIME type for files that use XML syntax to store structured data. It follows the +xml convention, which signals that the file contains XML. This means you can use standard XML tools to read or validate such files.

The file type is associated with data following a specific schema. Files of this type use the extension LOSTXML. This tells compatible applications how to parse the contained information.

• Structured data interchange: It facilitates sharing of complex data between systems.
• Validation and parsing: Its XML basis lets developers use common XML parsers and validators.
• Custom workflows: The specialized schema enables integration in particular application pipelines.

The MIME type ensures that software handling these files treats them correctly as XML documents with custom rules. For more on XML standards, visit the W3C XML site.
