Parameters of the graphical structure in the hierachy:

• Hierarchy is defined as the ancestry or carrying forward the characters from gross to more specific nature.
• The NDF structure is the first of its kind, comprising of all the kinds of graphical structures. The extension is .ndf.
• From the NDF structure comes the WCS component of a NDF.
• Then comes the HDS object, which is further more classification of WCS.
• Then comes the XML document.
• Then comes the file format .zip or .jar. We are more or less familiar with it.
• They are again classified into the FITS file. From which comes the normal file parts.
