XMF (Extensible Music Format) is a tree-based digital container format used to bundle music-oriented content, such as a MIDI file and optionally the sounds it uses, liner notes or other content grouped by language-codes. The first XMF definitions were to allow the bundling of a musical performance with the musical sounds used. For instance, a MIDI file could be stored together with a Downloadable Sounds file, and both files would travel together inside one XMF file. This specific use of an XMF file is referred to as XMF File Type 0 (streaming) or XMF File Type 1 (non-streaming), depending on whether the type of the MIDI file is 0 or 1, respectively. There are currently five XMF File Types defined. The latest of which is XMF File Type 4 (counted from zero) and is called Interactive XMF (iXMF). The specifications for the XMF was first published in 2001 by the MMA. == Features == * Resources can be referenced internally (in the XMF file) or referenced externally using a URI. * Resources can be country- and language-coded so that text could be shown in the right language depending on context. * Resources can be compressed using ZLIB. * Size information is stored using variable-length quantities, ensuring that the format can support an infinite number, while at the same time saving storage space. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「XMF」の詳細全文を読む スポンサード リンク
