Just wanted to check the consequences of the following dataset operation.

Say I have a dataset with 10 occurrences with occurrence ids 1-10. In my local 
database I now assign those 10 occurrences new identifiers a-j. If I create a 
new DwCA file for my data and crawl the new archive, my expectation is:

1. Old data with ids 1-10 is deleted from GBIF index
2. New data with ids a-j is indexed

So, end result is dataset has 10 occurrences. I'm asking because I know in the 
past the some datasets have changed identifiers and this has resulted in 
records with old and new identifiers coexisting in GBIF index, resulting in 
duplicated data.

Obviously it would be nice to have stable, unchanging identifiers for 
occurrences, but the for data set I'm working with the creators have changed 
their minds between versions of the data :(

Regards,

Rod
