StationXML to SEED conversion mapping chart

The following chart maps StationXML elements to their equivalent SEED Blockette numbers and fields.  Information external to SEED that may appear in StationXML is largely not shown, except where needed.  The nesting and ordering of XML elements are not shown in this chart, but attributes will be clearly marked with a leading dot and indent.  Blockettes and their data field numbers are referred to in the following way:

B050                        Blockette 50 (Station)

B050.f16                Blockette 50, field 16

B050.f10->B033.f4        Blockette 50, field 10 refers to a Blockette 33 by Abbreviation lookup code, then get value from field 4
