are recommended in different sources.From Darwin Core Quick Reference Guide
From Georeferencing Best Practices
Subsequently these recommendations affect downstream implementation such as:
Hence I would appreciate if there will be a general guidelines on how to treat different scenario of NITS (Nothing Interesting To Say) in Darwin Core. I appreciate Bob's suggestion on how to treat missing data in his post:
Thanks a lot!
