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.
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.
