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.
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.
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.
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.
ftpparse is a library for parsing FTP LIST responses. It currently understands the LIST output from any UNIX server, Microsoft FTP Service, Windows NT FTP Server, VMS, WFTPD, NetPresenz, and NetWare. It also supports EPLF, a solution to the LIST-parsing mess (supported by Netscape 5.0). ftpparse parses file modification times into time_t, so you can easily compare them and display them in your favorite format. It lets you know how precise the time_t is: LOCAL meaning exact with known time zone (available from EPLF), REMOTEMINUTE meaning unknown time zone and seconds, or REMOTEDAY meaning unknown time zone and time of day.
