Apache XML Graphics Commons is a library that consists of several reusable components used by Apache Batik and Apache FOP. Many of these components can easily be used separately outside the domains of SVG and XSL-FO. You will find components such as a PDF library, an RTF library, Graphics2D implementations that let you generate PDF and PostScript files, and much more.
Isobel is a framework to build complex information retrieval and analysis systems. Isobel can be functionally divided in two subsytems, Isobel Gatherer (the crawling and filtering subsystem) and Isobel Analyzer (the analysis subsystem). The two subsytems can also be used separately. Isobel Gatherer offers ready-to-use services like content fetching, scheduling, document format conversion, Hyperlink graph storage and analysis, content storage and indexing. A programmer may easily add new services. Isobel Analyzer uses the IBM UIMA architecture to reuse the analysis components developed for this architecture.
ProteomeCommons.org IO Framework is a proper Java framework for handling spectra and peak lists. The framework can read and write to a number of different spectra and peak list formats, and it provides a simple, intuitive Java object model for working with spectra or peak lists. All classes support two methods of handling peak list and spectrum data: in-memory or stream. The goal of this framework is to support all the popular MS and MSMS data formats, and to eliminate any time or effort involved in figuring out how to read and write peak list or spectrum files.
ProteomeCommons.org Java Analysis Framework is a framework for referencing common mass spectrometry data such as atoms and residues. This framework provides a programmer with an easy-to-use library for writing programs that rely on common mass spectrometry data. The framework also contains utilities such as an isotope calculator and a reference for residue abbreviations.
SNAP Platform is a development toolkit that packages into an easy to install solution the the Jikes Java compiler, the SableVM Java-like virtual machine and the GNU Classpath Java-like API, and the Eclipse universal tools platform, plus sample programs with source code and developer documentation.
