This is an old revision of the document!
SVN is a software versioning and revision control system which we use to store the FIR Definitions. It allows more people to work on the files at the same time.
The lead member of the dataprep team needs to publish the latest version for before it is available for public use. The server updates every 5 minutes so you need to wait after having uploaded to SVN.
You should update the date in your config.fir file. If you already made a change on that date you also have to update the revision number.
