TaxonHistory

tblTaxonHistory, history of concepts and nomenclature for protonyms.

   TaxonHistoryID, integer, 4 bytes, primary key, identifier for taxon name and concept.
   TaxonNameID, integer, 4 bytes, = tblTaxon.TaxonNameID, identifier for the monomial name (protonym) associated with the history.
   SeqNum, integer, 2 bytes, sequence number within this TaxonNameID, 1-based values without gaps.
   NomenclatorID, integer, 4 bytes, = tblNomenclator.NomenclatorID, identifier for binomial name associated with the history.
   CiteRefID, integer, 4 bytes, = tblRefs.RefID, identifier for the reference that defined the nomenclatural or concept change.  May = 0 if change comes from other source explained in note or if the reference has not been identified.
   NewNameStatusID, integer, 4 bytes, status of name when changed
       0 = unspecified
       1 = unchanged
       2 = new taxon name
       3 = made a synonym
       4 = made valid or temporary
       5 = new combination
       6 = name deleted with no related name
       7 = name deleted because of duplicate protonym, related name can be found in tblRelatedHistory
       8 = genus or species lowered to nominotypical sub
       9 = nominotypical sub raised to genus or species
       10 = name replaced by nominotypical sub
       11 = new nominotypical sub
   ConceptChangeID, integer, 4 bytes, values in effect on completion of the change, permitted values:
       0 = unspecified
       1 = unchanged
       2 = new
       3 = restored
       4 = expanded
       5 = shrunk
       6 = modified
       7 = terminated
       8 = transferred
   OtherHistoryID, integer, 4 bytes, = tblTaxonHistory.TaxonHistoryID, identifier for the other history ID involved in a relationship change specified in RelatedHistoryID
   RelatedHistoryID, integer, 4 bytes, = tblRelatedHistory.RelatedHistoryID, identifier for the type of relationship to OtherHistoryID
   UserConfirmed, bit, 1 = user has confirmed data in this row or generated from user supplied data in tblCites
   UnreliableAssumption, bit, 1 = program used an unreliable assumption to create row
   ArbitraryRow, bit, 1 = arbitrary row generated by program to resolve conflict, user resolution needed
   Note, text, 300 characters maximum. When Status is set = 2, values for NomenclatorID and CiteRefID are set = 0, but those items are expanded to text in this column.  When Status is set = 3, the domain name of the split out species file is placed in this column.
   Status, integer, 1 byte, status of the row
       0 = active
       1 = dormant, used for deleted nominotypical subs, which might be re-instated at a later time
       2 = artifact, used for rows erroneously added.  The row cannot be deleted once TaxonHistoryID has been exposed in an LSID or other GUID for a taxon concept.
       3 = moved to other species file identified in Note
       4 = moved out of scope
   LastUpdate, smalldatetime, date and time row last updated
   ModifiedBy, integer, 4 bytes, FileUserID of the signon that made the change
   CreatedOn, smalldatetime, date and time row was created
   CreatedBy, integer, 4 bytes, FileUserID of the signon that created the row
