Some of these "mappings" are going to be more useful than others. One kind of
mapping the DCES to Postscript might be to just print it out, for example; and
one kind of mapping to HTML would say "well, if we wanted to print this Dublin
Core out so it looked nice, what tags would we use to do that?" (that's option
2b in the working paper I'm hoping to announce here shortly). A useful mapping,
in my book, implies that the syntax of the target system is at least as
powerful as that of the source, in the sense that it allows you to represent
all the inter-relations, structure, distinctions etc. that a human reader
might wish to identify in the set of information carried by the DC. MARC
records probably do that but I'm less sure of the others. Mappings which are
lossy are, I opine, to be deprecated. Or why bother with em?
