Zorba is a general-purpose XQuery processor implementing in C++ the W3C family of specifications. It is not an XML database. The query processor has been designed to be embeddable in a variety of environments, such as other programming languages extended with XML processing capabilities, browsers, database servers, XML message dispatchers, or smartphones. Its architecture employes a modular design, which allows customizing the Zorba query processor to the environment’s needs. In particular, the architecture of the query processor allows a pluggable XML store (e.g. main memory, DOM stores, persistent disk-based large stores, and S3 stores).
The Marionette Collective (mcollective) is a framework to build server orchestration or parallel job execution systems. It uses modern technologies and concepts that make it ideal for large and cloud-based infrastructures. It's specifically geared towards systems administration tasks, but can be seen as a generic framework too.
Canorus is a cross-platform music score editor. It supports an unlimited number and length of staffs, polyphony, MIDI playback of written notes, chord markings, lyrics, and a number of import and export filters to many formats like MIDI, MusicXML, ABC Music, MUP, PMX, MusiXTeX, and LilyPond. It features multiple viewports of the same score, scripting support, score source view, and a fast and intuitive UI. It is based on Qt4, uses CMake as a project management tool, swig for scripting/macros integration (primary script languages are Ruby and Python), and the cross platform rtmidi library for MIDI playback. It is the official successor to NoteEdit.
REXML is an XML 1.0 compliant, reasonably fast, non-validating XML parser. It has an API that is designed to be intuitive, straightforward. and terse. REXML includes a tree model parser, a SAX2 streaming parser, and a pull parser. It also includes a full XPath implementation. All of REXML's parsers pass 100% of the Oasis XML non-validating tests. As of Ruby 1.8.0, REXML is distributed with Ruby.

utf8proc is a library for processing UTF-8 encoded Unicode strings. Some features are Unicode normalization, stripping of default ignorable characters, case folding, and detection of grapheme cluster boundaries. The library can be used in C programs, but most of the functionality is also available as a ruby library. For PostgreSQL, there is an extension providing a function for preparing strings in case insensitive indices. The currently supported Unicode version is 5.0.0.
