DEPRECATED: This library is no longer maintained. A fork of this library lives on in the Verovio project. This includes the most useful tool from this project, the ability to generate code from a new MEI Schema using the parseschema2.py script.

Libmei was an interesting concept when we started it, but there are much better XML libraries available that support nice features like XPath and proper namespaces. You're better off using those instead of this now.

LibMEI

Build Status

LibMEI is a C++ library for reading and writing MEI files

It is developed by the Distributed Digital Music Archives and Libraries Lab at the Schulich School of Music at McGill University, Montréal, Canada

License

LibMEI is released under the MIT license.

Compilation & Usage

We provide an XCode project for OSX and a cmake script for Linux.

To build on Linux, simply

mkdir build; cd build
cmake ..
make
sudo make install

To use libmei, include

#include <mei/mei.h>

We provide two sample applications to demonstrate use. util/readmei.cpp is a trivial example of reading and writing MEI, and making a change to the document structure. util/mxmltomei contains a tool to convert between MusicXML and MEI. This tool is still in active development.

More detailed information about compilation and use is available at the libmei wiki: https://github.com/DDMAL/libmei/wiki

Python

LibMEI ships with Python bindings using the Boost-Python framework. More information about installing and using these bindings can be found in Installing the Python bindings

Customization

One of the most useful features of the MEI specification is the ability to generate custom schemas (in RelaxNG, DTD or W3C Schema) containing only the music notation features that you require. For example, there is no need to validate documents written in mensural notation against the Common Music Notation features of MEI. Also, MEI allows you to define new customizations for musical features that may not be covered under the core specification. These are features inherited from the TEI project, and you can read more about them on the ODD Overview Page or in our paper about MEI and LibMEI.

LibMEI ships with tools that allow you to easily work with these customizations to limit or expand the functionality. In the tools directory we include a Python script, parseschema2.py that will generate custom code for you in either C++ or Python. (Other languages may be added as well, if requested).

You can read more about customization and custom compiliation on our wiki pages.

DEPRECATED: This library is no longer maintained. A fork of this library lives on in the Verovio project. This includes the most useful tool from this project, the ability to generate code from a new MEI Schema using the parseschema2.py script.
Libmei was an interesting concept when we started it, but there are much better XML libraries available that support nice features like XPath and proper namespaces. You're better off using those instead of this now.
LibMEI
Build Status
LibMEI is a C++ library for reading and writing MEI files
It is developed by the Distributed Digital Music Archives and Libraries Lab
at the Schulich School of Music at McGill University, Montréal, Canada
License
LibMEI is released under the MIT license.
Compilation & Usage
We provide an XCode project for OSX and a cmake script for Linux.
To build on Linux, simply
mkdir build; cd build
cmake ..
make
sudo make install

To use libmei, include
#include <mei/mei.h>

We provide two sample applications to demonstrate use. util/readmei.cpp is a trivial
example of reading and writing MEI, and making a change to the document structure.
util/mxmltomei contains a tool to convert between MusicXML and MEI. This tool is
still in active development.
More detailed information about compilation and use is available at the
libmei wiki: https://github.com/DDMAL/libmei/wiki
Python
LibMEI ships with Python bindings using the Boost-Python framework. More information about installing and using
these bindings can be found in Installing the Python bindings
Customization
One of the most useful features of the MEI specification is the ability to generate custom schemas (in RelaxNG, DTD or W3C Schema)
containing only the music notation features that you require. For example, there is no need to validate documents written in mensural
notation against the Common Music Notation features of MEI. Also, MEI allows you to define new customizations for musical features that
may not be covered under the core specification. These are features inherited from the TEI project, and you can read more about
them on the ODD Overview Page or in our paper about MEI and LibMEI.
LibMEI ships with tools that allow you to easily work with these customizations to limit or expand the functionality. In the tools directory
we include a Python script, parseschema2.py that will generate custom code for you in either C++ or Python. (Other languages may be added as well, if requested).
You can read more about customization and custom compiliation on our wiki pages.
