Empty rows are ignored.

For the purposes of dctap, a row is “empty” if it does not have a value either for shapeID or for propertyID.

The CSV:

shapeID	propertyID	valueNodetype
book
		literal
	dc:creator	uri
book	dc:date	literal

is interpreted as:

DCTAP instance
    Shape
        shapeID                  book
