|One possible set of DNA sequence data compression factors for the various experimental classes|
|Class||Description||Rate for Physically Unique samples||Rate for Physically Archived/archivable Samples|
|1||Historical sampling of environment or time specific elements||1.0||1.0|
|2||Very rare objects||1.0||1.0|
|3||Longitudinal studies which could in theory be rerun in the future but have a > 10 year horizon to recreate||1.0||2.0|
|4||Samples acquired from patients or animals with a high individual acquisition cost, but a conceptually continuous generation||1.0||10.0|
|5||A complex experiment with > 6 month resource development||10.0||100.0|
|6||A routine experiment with < 6 month resource development||20.0||200.0|
|7||Verification experiment as a component in an overall flow||1000.0||∞ (Infinite compression of data indicates no data archiving; it may, however, be useful simply to record that the experiment was carried out.)|
Compression is higher for data that are easy or inexpensive to reproduce, and lower for data derived from unique or irreproducible samples.
