The wftk is a relatively complete initial implementation of a workflow engine. It is implemented as a library to allow workflow functionality to be embedded in arbitrary applications. Data and activities are represented internally as XML structures, and all interfaces to external systems are organized into adapters to allow fairly easy interaction with any pre-existing software environment. The wftk compiles in both Unix and Win32 environments. Example adaptors already implemented are ODBC and Oracle under Windows, and MySQL for both Unix and Windows. There is an SMTP adaptor for Win32 and Unix, used for outgoing notifications. Storage of data is in local file directories or in databases.
DBStep is a library targeted at C++ developers who need to access databases. It consists of a common set of interface classes and some drivers for common data sources. Currently available drivers are for MySQL, PostgreSQL, SQLite, Firebird/Interbase, and ODBC databases. Database access is provided in at two levels: unified API for database connection, SQL execution, query result retrieval, and methods for mapping class objects to database tables and query results.

phpFeed is a system for retrieving and displaying RDF and RSS site summary files without requiring a database. Updating is done either on-the-fly when the page is loaded, or scheduled via a cron job. The layout and style of the display is fully configurable, and the configuration file itself is XML.
skstream is a network transport library written in C++ using the iostream interface. It provides classes for handling TCP socket connections. It is derived from the FreeSockets library by Rafael Guterres Jeffman. Its primary use to the WorldForge project, who maintain this version, is as a transport for Atlas-C++, the standard Atlas protocol implementation.
