Details

Functions passed into the assignment argument list of exportRecordsTyped() construct attributes on a column. They are expected to have a signature of function(field_name, field_label, field_annotation) and return the attribute to assign or NA. They must be vectorized.

stripHTMLandUnicode strips both HTML and UNICODE from the field_label.

unitsFieldAnnotation pulls a units string from the field_annotation. An example of the form searched for is units=\{"meters"\}
