Hi Tim, Simon, and Ivan, and all


Appendix A in prov-dm is normative, and changing it would .... you know 
what.

The group has decided not to formalise the translation between 
serializations, except
for the toplevel concepts listed table 10 of prov-dm.

We had a similar debate for translating types to xml.  We had left this 
to the translators
to solve.
