The National Space Science Data Center's (NSSDC) Common Data Format (CDF) is a self-describing data abstraction for the storage and manipulation of multidimensional data in a platform- and discipline-independent fashion. It consists of a scientific data management package (known as the "CDF Library") that allows programmers and application developers to manage and manipulate scalar, vector, and multi-dimensional data arrays.
Vortex Library is an implementation of the RFC 3080 and RFC 3081 standard definitions, known as the BEEP Core protocol, implemented on top of the TCP/IP stack. It comes with complete XML-RPC over BEEP RFC 3529 support, complete support for the TUNNEL profile (which allows you to perform proxy operations for every BEEP profile developed), support for HTTP proxies, and more. The API is consistent, easy to use, and allows you to write application protocols very quickly. The API is designed to allow bindings for other languages to be built easily.
Freesteam is a library that allows you to calculate water and steam properties using the industry-standard IAPWS-IF97 steam tables. It is a library of C++ classes which can be integrated into your code. Plug-ins to allow freesteam to be integrated with spreadsheets and other applications are under development. The included unit tests assure compliance with published property values. IAPWS-95 (scientific use) correlations are also included and used as part of this validation.
BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
GetData is a library that provides an API to interface with dirfile databases. The dirfile database format is designed to provide a fast, scalable format for storing and reading binary, synchronously-sampled, time-ordered data. GetData was originally written for the BOOMERanG and BLAST experiments as a data format suitable for use for both quick-look and data reduction. It is now used by many other cosmological and astrophysical experiments including ACT, Planck, Spider, Keck, as well as other projects.
Urwid is a Python library for making text console applications. It has many features including fluid interface resizing, support for UTF-8 and CJK encodings, standard and custom text layout modes, simple markup for setting text attributes, and a powerful, dynamic list box that handles a mix of widget types. It is flexible, modular, and leaves the developer in control.
libconfig is a compact, portable library for reading, manipulating, and writing structured configuration files. The library includes bindings for both the C and C++ languages, and works on Linux, Mac OS X, and other POSIX-compliant operating systems, as well as Windows. A complete manual with API documentation is included.
