## MIE Tags

MIE is a flexible format which may be used as a stand-alone meta information format, for encapsulation of other files and information, or as a trailer appended to other file formats. The tables below represent currently defined MIE tags, however ExifTool will also extract any other information present in a MIE file.

When writing MIE information, some special features are supported:

1) String values may be written as ASCII (ISO 8859-1) or UTF-8. ExifTool automatically detects the presence of wide characters and treats the string appropriately. Internally, UTF-8 text may be converted to UTF-16 or UTF-32 and stored in this format in the file if it is more compact.

2) All MIE string-value tags support localized text. Localized values are written by adding a language/country code to the tag name in the form `TAG-xx_YY`, where `TAG` is the tag name, `xx` is a 2-character lower case ISO 639-1 language code, and `YY` is a 2-character upper case ISO 3166-1 alpha 2 country code (eg. `Title-en_US`). But as usual, the user interface is case-insensitive, and ExifTool will write the correct case to the file.

3) Some numerical MIE tags allow units of measurement to be specified. For these tags, units may be added in brackets immediately following the value (eg. `55(mi/h)`). If no units are specified, the default units are written.

4) ExifTool writes compressed metadata to MIE files if the Compress (-z) option is used and Compress::Zlib is available.

See MIE1.1-20070121.pdf for the official MIE specification.

> Tag ID | Tag Name | Writable | Values / Notes
> --- | --- | --- | ---
> '0Type' | SubfileType | string | (the capitalized common extension for this type of file. If the extension has a dot-3 abbreviation, then the longer version is used here. For instance, JPEG and TIFF are used, not JPG and TIF)
> '0Vers' | MIEVersion | string | (version 1.1 is assumed if not specified)
> '1Directory' | SubfileDirectory | string | (original directory for the file)
> '1Name' | SubfileName | string | (the file name, including extension if it exists)
> '2MIME' | SubfileMIMEType | string |
> 'Meta' | Meta | - | --> MIE Meta Tags
> 'data' | SubfileData | undef | (the subfile data)
> 'rsrc' | SubfileResource | undef | (subfile resource fork if it exists)
> 'zmd5' | MD5Digest | string | (16-byte MD5 digest written in binary form or as a 32-character hex-encoded ASCII string. Value is an MD5 digest of the entire 0MIE group as it would be with the digest value itself set to all null bytes)
> 'zmie' | TrailerSignature | undef | (used as the last element in the main "0MIE" group to identify a MIE trailer when appended to another type of file. ExifTool will create this tag if set to any value, but always with an empty data block)
