[Esip-infoquality] Peng's slides: FW: IQC telecon

Hi Chung-Lin,

I do not think that you are overly concerned with regard to data rescue/preservation although I must admit that I struggle with the distinction between the two terms. To me, data rescue means preserving for the future data that is in danger of being lost. Regardless of how it is defined, there are a LOT of data that are in danger of being lost and there are horror stories of massive amounts of data that have been lost. For example, I have boxes of data on old digital media that may no longer be recoverable but that may be of value, if not now, in the not too distant future. Although the data may not be documented to the extent required for some applications they may be for others. For example, VHRR data (the predecessor of AVHRR) extended back to 1975. They were of too low quality to provide good sea surface temperature fields but they were fine to delineate the edge of the Gulf Stream and the large eddies in the vicinity of the stream — both extremely important in climate considerations. But, because they did not provide good SST values they were discarded. In a changing climate with questions about possible changes in the Gulf Stream these data might have been of significant value now had they been preserved/rescued. The problem is that decisions to retain data often do not look into alternative uses of the data or value that the data may have in the future. It is also particularly galling that the cost of preserving the data is relatively low compared to the cost of collecting it.

In any case, I’m truly glad and grateful for having professional peers like you with both knowledge and conscience.  Thanks again!

> The data rescue issue touches on many different areas and perspectives – some of those are beyond the scope of data preservation. It can be related to rescue data from its obsolete format such as physical records. It can also be related to rescue data from politically endangered data sources as you have mentioned. You may have already known that ESIP DSC had a session at the ESIP 2018 Summer Meeting to identify data risk factors – there are a lot of them!

> In my opinion and generally speaking, if a dataset is well-managed, well-preserved, well-documented, publicly available and usable, the risk for it to disappear is low; so is the need for it to be rescued. Perhaps, stewardship maturity models can be used to measure the data risk and the need of data rescue from the stewardship practice perspective.

>> Peng, thank you very much again for giving an excellent presentation full of crucial and useful info.  Just one more comment: wonder the WMO SMM-CD might also consider to include “data rescue” into “data preservation” if not yet?  The “news” about the Department Interior’s recent request to destroy data, if indeed true, should have concerned us, in my opinion.  Thanks.  – Chung-Lin
