I've take the liberty of correcting the key technical details per option,
and removing the copy of the old votes (which are still on the original

In particular I've tried to clarify the confusion caused by loss of the
mime-type discussion of Option 5, and its subsequent unwarranted
transference of implication to option 8 - and restore the correct

Option 1 - cannot go from SOSA to OWL axioms
Option 5 - relies on content negotiation to find OWL axioms bundled with
SSN extensions
Option 8 - use owl:imports to find OWL axioms and keep SOSA axioms separate
from SSN narrowed semantics

Again, I reiterate my concern that the use of the phrase "SOSA imports SSN"
to characterise option 8 is incorrect unless you explicitly interpret SSN
to be nothing more that the axiomitisation of SOSA, and I dont believe
anywhere we have agreed on that exact definition.

I think that we can revisit the three options now with greater focus, and
without reference to other options we have taken off the table.
