Additional security considerations associated with this type have not been assessed. Interoperability considerations : None Published specification : The Open Score Format Packaging Specification describes the format of the compressed container: http://openscoreformat.sourceforge.net/ W3C XML Schemas for all XML documents used in the container can be found at the same location. Applications which use this media : Containers primarily contain a digital score (sheet music) conforming to a restricted subset of MusicXML 2.0. Many existing applications capable of reading and writing MusicXML 2.0 files are also capable of reading the contents of an uncompressed container. A list of applications can be found at: http://www.recordare.com/xml/software.html Recordare's Dolet 4 MusicXML import/export plug-in for Finale is capable of directly reading and writing Open Score Format containers. The Open Score Format Packaging Toolkit can be used pack, unpack and validate containers. It can be used with application lacking native support for Open Score Format to provide access to the digital score in the container. The Open Score Format Packaging Toolkit is available at: http://openscoreformat.sourceforge.net/ Additional information : 1. Magic number(s) : None 2. File extension(s) : osf 3.
