This paper covers some good requirements from the geospatial community.

I have one question/clarification on the example used to grant the
display permission for the asset at the "resolution of 1."
Is this characteristic part of the data or the display device?

If it is the former, the ODRL has a "quality" constraint, and all you
need to define is a URI for "resolution", for example:

<o-dd:display>
	<o-ex:constraint>
       <o-dd:quality o-ex:type="geospatial:resolution">
          <o-ex:constraint>
             <o-dd:range>
               <o-dd:max>1</o-dd:max>
             </o-dd:range>
          </o-ex:constraint>
       </o-dd:quality>
     </o-ex:constraint>
</o-dd:display>
