Hi David!

this sounds great. My understanding is that there should be no
strict/formal structure to metadata, so in light of the perfectly
legitimate scenario you describe, it would be best that provide generic
converters, which subclass the ones we have available, and then decide to
only include, or selective exclude content based on the cell metadata. This
might even be a mixin for the converter classes we have now, so at the
command line you could do something like --ignore-metadata='solution', or
--only-metadata='awesomeness'
