(GENERAL) Transform author name abbreviation to TDWG standard

Access query (in Excell use Substitute instead of Replace):
standardAuthor: Replace(Replace(Replace(Replace([Author],". ","."),".ex",". ex"),".in",". in"),".&",". &")

(SPECIFY) Identify autonyms

Access VBA in query: isAutonym: IIf(findOccurancesCount([CanonicalName],[Name])>1,True,False)
VBA Function: Source

  Function findOccurancesCount(baseString, subString) As Integer

     baseString = Nz(baseString, " ")

     subString = Nz(subString, " ")

     occurancesCount = 0

     i = 1

     Do

         foundPosition = InStr(i, baseString, subString) 'searching from i position

         If foundPosition > 0 Then                       'substring is found at foundPosition index

             occurancesCount = occurancesCount + 1       'count this occurance

             i = foundPosition + 1                       'searching from i+1 on the next cycle

         End If

     Loop While foundPosition <> 0

     findOccurancesCount = occurancesCount

  End Function

(SPECIFY) Derive canonical name from FullName

Access-VBA in query:
canonicalName: IIf(InStr(Nz([fullname]),":")>0,Mid([Fullname],InStr([fullname],":")+2),[Fullname])

(SPECIFY) Create fullNameWithStandardAuthor

Access-VBA in query: (Omits author citation for autonyms)
fullNameWithStandardAuthors: IIf([isAutonym],Nz([canonicalName]),Nz([canonicalname])+" "+Nz([standardauthor]))
