Peter Fox and Deborah McGuinness have previously discussed some work
similar to this on the Virtual Solar-Terrestrial Observatory  using
Proof Markup Language (PML)  to represent the provenance of data
ingest and processing, including encoding reasons for missing or bad
data, and inferring reasons for later missing data (because the
earlier data was missing, for example).
