-- Terms marked with ^ indicate that the specified term is accepted in the Event or Occurrence table, but preference is that they be recorded in the eMoF table to link with controlled vocabulary
+- Terms marked with 1 indicate that the specified term is accepted in the Event or Occurrence table, but preference is that they be recorded in the eMoF table in the measurementType column so they can be linked with controlled vocabulary
 - For the Occurrence table, distinction is made if the term could be used in the core or the extension table
-  - x/x = term can be used in either Occurrence core or extension
-  - x/- term is recommended only for the Occurrence core
-  - -/x term is recommended only for the Occurrence extension
