mess822 is a fast library for parsing Internet mail messages, with several qmail-compatible applications. It supports the full complexity of RFC 822 address lists and common RFC 822 extensions, and extracts each address as an easy-to-use string, with a separate string for the accompanying comment. mess822 also converts RFC 822 dates into libtai's struct caltime format, with support for numeric time zones, the standard old-fashioned time zones, and many nonstandard time zones.
HL7lib is a project that will provide a free, correct implementation of Health Level 7 functions. Health Level 7 is commonly used in large hospitals to send patient information among computer systems from different vendors. Since there is no reference implementation of HL7 many of these vendor systems vary widely in their interpretation of HL7.
JORA will simplify your development of database applications, establishing implicit mapping between relational database tables and Java classes. JORA uses JDBC for database connection, so it can be used with any database supporting JDBC or ODBC. JORA also allows you to use object-oriented features, such as polymorphism and complex objects, in your database applications.
MatLisp is a set of CLOS classes for handling matrices. The classes allow a simple and consistent interface to matrix operations. Matlisp is powered by the well-known and well-tested linear algebra packages BLAS and LAPACK, which provide the Matlisp user an immediate interface to a set of specialized and well-documented linear algebra routines such as +, -, *, /, eigenvalue, SVD, Cholesky decompositions and more.
PAT is an interpreter for a scheme-like functional language, also named PAT. It is written completely in Java and can run on any Java supported platform. Since the language is Turing-complete, it can be used for any type of computer application. It was originally developed to do performance analysis using list manipulation. However, it has grown into much more than that and can be used for many things, including: interactive testing of code written in Java, reading/writing Java objects from/to XML files, launching applications remotely. Some of the features of PAT are built-in lists and common list procedures such as filter, sort, map, append, and foreach; math primitives for arithmetic, statistics, trigonometry, and random numbers; built-in objects for dates and times; reflection primitives for introspection of Java objects; a table library; and simplified syntax for interactive Java object manipulation. It runs on Linux, All Java Platforms, Windows NT, Windows 2000
