XFP Extensible Filtering Pipelines

XFP is a framework for building data management procedures using XML-based configuration files. XFP is also a server that provides scheduled execution of your procedures and flexible logging. Typical use-cases include data feed management and content syndication. XFP can manage (in a coherent and centralized way) data coming from different sources, lowering development and maintenance costs. Instead of writing your own code for each data feed, with XFP you can split code into reusable components (called "filters").
