[LDM #MIY-342905]: Questions about LDM 6


> WeÂdeeply appreciate your recommendations that help us a lot.
> CWB in Taiwan developedÂthe interface which was based on LDM-4 fifteen years

> We plan to spend several years getting this job done.ÂDuring the transition

> That's why we would like to use LDM-6 interface complexly.
> We find that LDM-6 can notÂreceive files with the same content repeatly. 
> Would you please tell us how to remove this restriction?

The product-queue module will not write a data-product into the product-queue 
whose MD5 checksum is identical to that of a data-product that's already in the 
product-queue. This is done to reject duplicate products and was a deliberate 
design decision.

If you must work around this feature, then I suggest including a timestamp in 
the data-product's data. This will make the MD5 checksums different for 
data-products that are, otherwise, identical.
