Hi Zach
Thanks for filling us in on your team's understanding of "completeness". Just as you thought!
Clearly they have an interactive process that allows calculation of the expected number of species
If you could get more details of how that is implemented operationally Zach it would help us describe this usage and its application. This added information will be helpful in finding additional terms when revising the extension.
I think we have three different ideas now of how "completeness" can be interpreted.
Safe travels to Zach and Steve along with the other 55 million people AAA says will be on the highway!
PS We are hosting not traveling so I will be on line at 8 am incase people what to discuss issues.
Thanks again Zach. Happy Thanksgiving to all. Rob

Hi everyone,
Following up on our conversation from last week about completeness, I spoke with a couple ecologist colleagues about their understanding of the term. Here is a summary of their responses:
Person 1) I think of completeness as a calculated variable. Completeness is valuable if you want to know if you’ve put in enough effort to have observed all the species present. Completeness is sometimes reported in the compiled report of an inventory for some taxonomic groups (our inventories typically survey amphibians and reptiles, birds, fishes, mammals, and plants). These groups usually report every species within their taxonomic scope that they observe, although sometimes the mammals team focuses on large and volant mammals. People may want to use a calculated number to represent completeness, but then we are getting away from providing raw data and getting more into analysis. Ways we could calculate completeness would be species accumulation curves, or # species observed / # species expected.
Person 2) My understanding of completeness in this context is the proportion of all expected species in the sampling area that were observed during sampling. The way we would calculate that is to record the # species observed and divide it by the # of expected species according to a trusted, independent source.
I hope that is helpful. Please let me know if I can clarify anything.
I will be traveling tomorrow so I will not be able to attend our meeting this week. See you all the following week!
Best, Zach

Hi all!
Hope everybody is well!
I am very sorry, but I will not be able to lead the meeting tomorrow. I encourage you to meet and finish discussing what we learnt during the testing phase (see *these slides https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdocs.google.com%2Fpresentation%2Fd%2F18n83tttDvWDLI5UM30LIsfqrbpH5nbyrwIKjuUY_glE%2Fedit%23slide%3Did.p&data=05%7C01%7Cyanina.sica%40yale.edu%7Ce861023cb02b4dc0783108dabc4235cf%7Cdd8cbebb21394df8b4114e3e87abeb5c%7C0%7C0%7C638029289805968080%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=gVGOkHUTLwq68IMn0H8JnwMiRYmMmUq9WtiViqfbohE%3D&reserved=0 for reference). * Specifically, we should discuss if we want to incorporate two terms:
- isInventoryComplete (if user reported every species observed)
- speciesCount (if user wants to report the total species observed)
If so, we need proposed* term names, descriptions and examples*.
We also need to start preparing for the next steps. Steve, is there a document that we should start completing for the public review?
Very sorry for the short notice, but I will need to make a last-minute trip tomorrow morning.
