I certainly agree with that point:    (02)

But the SemWebbers succeeded in making KIF look readable by
inventing the most unreadable formats ever inflicted upon
a significant number of users.    (04)

As an example, following is the KIF (or CLIF) representation
for a list of RDF triplets:    (05)

      (R1 A1 B1)
      (R2 A2 B2)
      (R3 A3 B3)
        . . .
      (Rn An Bn))    (06)

The SemWebbers respond to this point by saying that they have
developed humanly readable notations for making RDF and OWL
more readable.  I would respond with two points:    (07)

  1. Any notation that is so unreadable that even professionals
     must use such aids is seriously flawed from the beginning.    (08)

  2. There are many different such tools, different people
     use different ones, and many, if not most, users are
     forced to read the unreadable.    (09)

There are often good reasons for inventing new notations,
but it would be helpful to make them interoperable and
automatically translatable to anybody's favorite human
or machine-oriented notation.    (010)

Following is a diagram that illustrates that point:    (011)
