[eml-dev] EML and ISO19115

[Matt Jones]

There is a lot of overlap among all three metadata specs.  Portions of EML
are in the FGDC standard and vice versa, and portions of 19115 are in EML.
 EML also incorporates metadata from ESRI's FGDC implementation that was
missing in the real  FGDC  and ISO.  Probably > 80% will be isomorphic and
easily mapped, so I think the mapping is the easier part of the process.
 The hard part is the transformation itself, and in particular the
transformation at the point where the models diverge.  The hard decisions
are what to do when the transformation will be necessarily lossy or
imprecise due to granularity mismatches, or how to manage for missing
content that is required in one specification but optional and therefore not
provided by the user in the other.  The FGDC/EML stylesheets encode a bunch
of these logistical decisions, and represent a compromise on hard situations
where the mappings break down.
