Xapian is a search engine library, scalable to collections containing hundreds of millions of documents. It's written in C++ with bindings for Perl, Python, PHP, Java, Tcl, C#, Ruby, and Lua. It is a highly adaptable toolkit that allows developers to easily add advanced indexing and search facilities to their own applications. It supports the Probabilistic Information Retrieval model and also a rich set of boolean query operators. Omega is a Web search application built upon the Xapian library. It can index a Web server's document tree (including HTML, PDF, OpenOffice, MS Word/Excel/Powerpoint/Works, WordPerfect, RTF, PS, etc.), or data exported from arbitrary sources (e.g. SQL databases).
mididings is a MIDI router and processor for ALSA and JACK MIDI. It supports filtering and modifying MIDI events in many different ways, and allows for seamless switching between different patches even while playing. mididings is scriptable and extensible in Python, while the core MIDI processing code is written in C++ in order to allow low latencies and realtime usage.
Peers is a distributed programming toolkit designed for building peer-to-peer systems. The toolkit is a hybrid language project which offers low level primitives for managing concurrency and communication. Using these primitives, complex P2P protocols and complete systems can be designed and implemented in Python, while maintaining high performance for critical operations.
Berkeley DB XML is a native XML database engine for use within your product. Made available as a C++ library with language bindings for Java, Perl, Python, PHP, and Tcl, it integrates directly into your application (it is not a standalone database server). It provides XQuery access into a database of document containers. XML documents are stored and indexed in their native format using Berkeley DB as the transactional database engine.
