This library is published under the GNU Lesser General Public License (LGPL) v3+. All modifications (C)opyright 2013–2016 by Hanns Holger Rutz, released by that same license. Modified source files are marked in the header. The kind of modifications, file removals etc., are documented by way of the git history. Why a fork? (a) I needed to get an easy handle on the source. (b) I am planning to strip this down to a plain score display component. (c) Github instead of Google-Code. (d) Building with sbt. (e) Publishing (eventually) to Maven Central, making it available for automatic dependency management.

music-encoding - 美 The Music Encoding Initiative Schema

•    XSLT

The Music Encoding Initiative (MEI) is an open-source effort to define a system for encoding musical documents in a machine-readable structure. MEI brings together specialists from various music research communities, including technologists, librarians, historians, and theorists in a common effort to define best practices for representing a broad range of musical documents and structures. The results of these discussions are formalized in the MEI schema, a core set of rules for recording physical and intellectual characteristics of music notation documents expressed as an eXtensible Markup Language (XML) schema. It is complemented by the MEI Guidelines, which provide detailed explanations of the components of the MEI model and best practices suggestions. One of the core strengths of the MEI Schema is that it allows an individual to validate an MEI file against an XML Schema to ensure the MEI file conforms to expected encodings and behaviours. To validate an MEI file you need XML validator software. XML Authoring tools, such as oXygen has built-in validation tools. There are also several command-line utilities, including xmllint and jing.
