The CASE Data Exchange Format (CDIF), which seems to be no longer maintained, was defined to allow data exchange between different CASE tools and repositories. However, CDIF is general enough to allow the encoding of arbitrary data. CDIF supports multiple syntaxes and encodings. A textual encoding (called ENCODING.1) is defined as well.
