MULTIBEAM QUALITY ASSESSMENT METADATA
(draft schema)

<datafile> (being assessed)
<repository> (e.g. NGDC, CCOM, LDEO,… or local directory name)
<entry> (e.g. cruise) *
<filename>
<url>
<md5checksum>
</datafile>

<date> (of assessment)

<operator> (who performed assessment) *

<tool> (used to assess)
<id> (e.g. CUBE, mbhistogram) *
<score:normalized> 0.0 <= x <= 1.0
(is tool-specific, however, the scaling is consistent across tools (perhaps
linear?); we don't expect to know how to (robustly) relate the values of
different tools to each other anytime this decade but we might eventually)
<score:raw>
<normalization_equation>
<version> (must increment if the normalization eq. changes)
<description> (how the tool works, how it calculates a score)
<url> (where to read more)
<inputs> (structured text for now i.e. command arguments)
<outputs> (structured text for now)
</tool?
