Thanks - it's very valuable to have discussions

My personal opinion is that it's the best of a number of alternatives, but
if there is a coherent chunk of XML keep that as XML.

If the question is "should we have our own microsyntaxes?" I wouls suggest
not, and use RDF instead.

This is what I would favour. The order can be retained, but it's more
verbose

3) As one triple (MARC form)

My opinion (and I am new to this) is that microsyntaxes like this cause
downstream problems. We have to have a MARC parser as well as an RDF parser.
And not all or records will be MARC.

I would prefer to see some discussion as I don't understand all the issues.
And in these cases the availability of code may be the deciding factor.
