This page shows a live example of extensions to the projects VexFlow (a music rendering JavaScript library) and MEItoVexFlow (a JS program to render MEI scores using VexFlow).

Most of the extension work is focusing on MEItoVexFlow to extend the support of MEI elements (I have been the main development since November 2011). Such as the repetition signs with multiple endings in the example above.

Changes to VexFlow include support for lyrics, musica ficta and crescendo / diminuendo signs. MIT's music analysis library Music21 uses my latest build for in-browser music display.

I wrote this XSLT 2.0 for migrating the MEI schema specification (expressed in RelaxNG) into TEI ODD.

*The program creates ODD modules and determines which RelaxNG declarations fit better into an ODD model or a macro. The resulting organization is then reflected in the content of elementSpec declarations. The user is given warnings and structured information about the decisions made by the program through xsl:message instructions.

The XSLT is specific to the source MEI schema specification, but large parts of it could be used to perform more generic RelaxNG to ODD transformations.*

I started working on this after promoting the use of ODD as a member of the MEI advisory board. Here is a white paper that I submitted to the rest of the board in 2010.

The ODD resulting from this conversion has since been edited by hand and has been adopted as main source for the new release of MEI (forthcoming in the ne

The Integrating Digital Papyrology was an international project that joined together several databases of (mainly) Greek papyri; converted them to Epidoc, a fully conformant TEI P5 flavour. It formed the basis of the editorial project papyri.info.

The source databases had many differences not only in the way the data was structured, but also in the representation of ancient Greek alphabet and editorial intervention. A number of tools were created by the project team (I contributed to the development of some of the tools as well) and I wrote the Python script below to "run" all the programs according to parametrized requirements.

Some of the programs called are XSLTs, which are passed to one Saxon instance through a socket (instead of opening and closing Saxon at every transformation).
