I'd like to hear the practices of anyone who is actually using (or mapping) DwC to represent pollen specimens that reside in a collection different from the collection from that of the source. Especially: 1. Do you represent the pollen gathering as a different collection event from that of the source specimen. 2. What do you use to link the pollen specimen to the source specimen 3. If you use any DwC values of the source, do you make any attempt to synchronize changes to the source record with those of the pollen record. How? I really, really, would like to first hear answers from people currently doing this before people not doing it weigh in on what they think should be done. If you have service addresses at which I can fetch some pollen and source DwC records, that would help. Thanks Bob Morris -- Robert A.
