Happy new Year, OpenXDF and Compression

We're looking for a better and smarter way to save our data. We discovered the OpenXDF-format which just turned to version 1. The quintessence of the format for me is the differenciation of the signal data, the video data and the rest. So you can use ISerializable to easily serialize all the data (events, patient data, etc.). OpenXDF proposes to add all the files to a compressed file.

In .net, you can use System.IO.Compression to compress a file but you need extra work to handle files like in a zip archive (see the Compression Application Sample for how to do that).
