Impressive suggestion! As you noticed, there are various pros and
cons to this approach, which BTW can be made compatible with the
current approach. Chaals already raised the main issue (which may
or may not be a problem), which is that this method leaves less
room for extensibility and dual typing - depending upon how it's

There are a few options and paths for giving the type of the test
subject - for example, how many earl:isa (or earl:subjectType,
perhaps) properties is one allowed to have on a TestSubject?
Should the types be explicitly enumerated, or extensible?

The play off (similar to niq's Implementation vs. Stabilization
conundrum) is between making things simple and regular for
lower-end tools, but powerful and flexible enough for later
high-end tools.

Hmm... I think someone proposed this before, although I can't
find a reference, so I might be mistaken. It makes the XML RDF a
bit verbose if you have an anonymous assertor asserting lots of
assertions (that could go into the twelve days of EARL), but I
think that the choice is arbitrary either way. In fact, one can
just use [ daml:inverseOf earl:asserts ] in any case, so both
methods are acceptable from a coherent data POV.

Choices, choices...

Kindest Regards,
