+== Data Organization ==
+
+The data organization describes the physical meaning of the independent
+variable(s) with respect to which the observables are measured.  This is
+useful for knowing whether and how different data sets can be directly
+compared, overlaid, mapped, or otherwise transformed.

+  The following values are recognized:
+
+
+  ''' image '''
+
+
+    data organized by two dimensions corresponding to angular displacement
+    along the axes; examples include photograms (digital or digitized
+    photographs), spectroheliograms, magnetograms, and Dopplergrams
+
+  ''' map '''
+
+
+    data organized by two dimensions corresponding to spatial displacement
+    along the axes; examples include synoptic charts
+
+  ''' time_series '''
+
+
+    data organized by one dimension corresponding
+    to temporal displacement along the axis; note that this is not the
+    same as a time-tagged set of data records, since it implies sampling
+    uniformity and provision for data gaps
+
+  ''' movie '''
+
+
+    data organized by three dimensions corresponding to spatial or
+    angular displacement along two axes and temporal displacement along
+    the principal (most slowly varying) axis
+
+  ''' spectrum '''
+
+
+    data organized by one dimension corresponding to displacement in
+    electromagnetic wavelength or frequency along the axis
+
+  ''' mode_spectrum '''
+
+
+    data organized by one or more dimensions corresponding to the quantum
+    numbers of oscillations
+
+  ''' spectral_temporal '''
+
+
+    data organized by two dimension corresponding to displacement in wavelength or frequency along one axis and temporal diplacement along the other
+
+  ''' spatial_spectral '''
+
+
+    data organized by two dimensions corresponding to spatial or angular image axes and one corresponding to electromagnetic spectral displacement
