mappings/VegCSV-VegBIEN.specimens.csv: locationID: Removed mapping to locationevent.sourceaccessioncode, because locationID relates to the plot, not the plot event. (The locationevent is scoped by the location when the sourceaccessioncode and authoreventcode are not specified, so duplicate elimination will still occur correctly.)

mappings/DwC2-VegBIEN.specimens.csv: Mapped locationID, for mergability with VegCSV

mappings/VegCSV-VegBIEN.specimens.csv: plotName: Removed authoreventcode mapping because plotName relates to the plot, not the plot event. (The locationevent is scoped by the location when the authoreventcode is not specified, so duplicate elimination will still occur correctly.) Instead map only authoreventcode-related fields (currently CVS's authorObsCode) to authoreventcode, via DwC's (confusingly-named) fieldNumber ("An identifier given to the event in the field").

schemas/vegbien.sql: locationevent: locationevent_unique_within_location: Added authoreventcode to index. It was already in the locationevent_unique_within_*parent*_by_authoreventcode index, but also needed to be in the no-parent (non-subplot) index. This fixes locationevent duplicate elimination when a locationevent sourceaccessioncode is not specified.

schemas/vegbien.sql: location: location_unique_within_datasource unique index: Added COALESCE and `WHERE sourceaccessioncode IS NOT NULL` now that sourceaccessioncode is nullable. Renamed location_unique_within_datasource and location_unique_authorlocationcode to location_unique_within_datasource_by_... to show that both are alternatives for globally unique keys. schemas/vegbien.ERD.mwb: Moved elements slightly to reduce the number of lines that need to be repositioned after syncing with the schema.

mappings/DwC2-VegBIEN.specimens.csv: Mapped verbatimElevation and samplingProtocol, for mergability with VegCSV

inputs/import.stats.xls: Updated with stats from latest import

mappings/VegCSV-VegBIEN.specimens.csv: location unique keys: Map to a new parent location for the location, instead of a parent locationevent for the locationevent. This much simpler mapping (which does not require _alt or _merge) is possible now that the necessary unique indexes have been set up.

Regenerated vegbien.ERD exports, now including both pages in vegbien.ERD.core.pdf. Renamed schemas/vegbien.ERD.core.pdf to vegbien.ERD.pdf because it now includes the full schema.

schemas/filter_ERD.csv: Removed extraneous lines to improve readability. schemas/vegbien.ERD.mwb: Reconfigured elements to put only the most important ones in the core subset (the top page).
