          pts = {{0, 0}, {1, 1}, {2, 3}, {3, 4}, {4, 3}, {5, 0}};
          f = Interpolation[pts]


          interp_func



          I extracted the property values from the property list with PropertyValue and made an association with the properties names as keys for ease of examination and access.



          propAssoc = Association[{# -> PropertyValue[f, #]} & /@ PropertyList[f]]


          warning



          assoc



          The association can be queried to get individual property values.



          propAssoc @ "Domain"



          {{0, 5}}




          but, of course, if we don't want the bother of making an association just to get one or a few property values, we can use



          PropertyValue[f, "Domain"]



          {{0, 5}}




          which seems always to be safe.



          However, be aware that f itself acts like an association when given a valid property name and, also being safe, should probably be considered the standard practice for accessing properties.



          f @ "Domain"



          {{0, 5}}

            Is this meant to be sort of a canonical question/answer that we can point to whenever someone is wondering how to extract information from an InterpolatingFunction? And, if so, isn't the canonical answer just your very last paragraph?

            I mean, I definitely like the Association construction, since it has both the possible property names and their values all in one object, easily accessible and readable (rather than having to remember what properties there are). So, I get it!
