Design backwards-compatible data saving system
I think it may be well spent time to think about how one could save LV-Objects in a manner that still allows to load it after the class was updated. Example: During I020, I saved some SABER-files that I wish to use for data evaluation now. Since the "valid"-field was removed from the class, I cannot load them in the latest versions of WOMBAT and need to check out older versions.
The solution may not be trivial, but a combination of object serialization (maybe XML?) and object specific version IDs that are stored in the class itself could work. Here, one could implement a deserialization method that first retrieves the version ID and then converts the rest of the data accordingly into the most recent version.
