Re: duplicates in the FUNGI & LICHEN checklist
Back in February I discovered that the majority of Fungi in our version of the FUNGI & LICHEN checklist have two entries, one from the original BMS version of the list, and one from the updated NHM version. I had assumed at the time that this was due to my messing about with the dictionaries, but from discussions with Mike Weideli and Sally Rankin it appeared that it was not my fault.
The last message I had on the subject was from Mike:
The problem is in the Dictionary or the way in which Recorder 6 handles Taxon_List_Versions. The Fungi and Lichen list does have multiple Taxon_Determinations attached to the same Taxon_Version, which is unusual, but I thought acceptable.
The two entries show up when you do search. One can be found, but the other causes an error. The parent keys are not there for the ones causing error.
I don’t fully understand how this should work, but it would seem that both Taxon_List_Item _Keys are valid. In which case Dave does not have a problem but just needs to use the one which works for future entries. Existing records should be ok.
To demonstrate the problem search the Fungi and lichen list for Abrothallus cetrariae
To be perfectly honest I had completely forgotten about this issue as I have not done any data entry myself for some time, and it is only with recent staff changes that it has resurfaced. It does not represent a major problem, but I would be far happier if there was only one entry in the dictionary for our data entry staff to choose from. Does anyone know whether the problem has been looked at? It seems fairly simple to only allow data entry screens to access the taxon with the greater Taxon_List_version...
