FreeMED is an opensource electronic medical record system based on Linux, Apache, MySQL and PHP (commonly referred to as LAMP or LAMPS).
The FreeMED project was officially started in 1999 by a single developer in the United States. Since then, it has become an international effort, with thousands of downloads and several internationalizations.
FreeMED is currently hosted by the FreeMED Software Foundation, with downloads hosted by Sourceforge.
It uses Subversion as a Concurrent versioning system, which it has used since it was migrated from CVS in 2005.
FreeMED uses an external billing program called REMITT (REMITT Electronic Medical Record Information Translation and Transmission). The name "REMITT" is a Recursive acronym. It communicates with REMITT via an authenticated XML-RPC connection. This connection, once established, allows the transmission of medical billing data as a monolithic chunk of XML. This is then processed into a meta-format via XSLT, and finally processed into its final format and transmitted to its ultimate destination.
This methodology allows for multiple formats of output to be generated from the same base data.
