The Universal Container Format (UCF) was developed by Adobe for use in [[PDFXML]]. It is based on the Open Container Format (OCF) used in [[EPUB]], itself based on [[OpenDocument]]. It specifies a mandatory initial uncompressed <code>mimetype</code> file, and an optional <code>META-INF</code> folder containing [[XML]] files.

It can contain [[XMP]] metadata in the file <code>META-INF/metadata.xml</code>.

Some formats include <code>+zip</code> at the end of the <code>mimetype</code> file's contents, and some do not.
