Folks,
I am relatively new to the world of metadata and have exhausted my web
search
capacities in an attempt to address the issue below.
I am modifying UnidataDD2MI.xsl.2.3.4 to accommodate WRF model netcdf data
on a Lambert Conic projection.
If it is not appropriate that I address this group regarding this, I would
be monumentally grateful if anyone could please suggest an appropriate
avenue of pursuit. Thank you!

I wish to describe a Lambert projection in more detail than apparently
allowed by gmd:referenceSystemInfo using the http://www.isotc211.org/2005
standards, i.e.:
<gmd:referenceSystemInfo> <gmd:MD_ReferenceSystem>
<gmd:referenceSystemIdentifier> <gmd:RS_Identifier>
<gmd:code> <gco:CharacterString>
Lambert Conformal Conic Projection with 2 std parallels
LCC(2SP) EPSG:9802
</gco:CharacterString> </gmd:code>
<gmd:codeSpace> <gco:CharacterString>
EPSG
</gco:CharacterString> </gmd:codeSpace>
</gmd:RS_Identifier> </gmd:referenceSystemIdentifier>
</gmd:MD_ReferenceSystem> </gmd:referenceSystemInfo>
I would like to find a place to add the projection parameters, e.g.:
<gmd:projectionParameters> <gmd:MD_ProjectionParameters>
<gmd:latitudeOfProjectOrigin>34.5</gmd:latitudeOfProjectOrigin>
<gmd:longitudeOfCentralMeridian>-135.0</gmd:longitudeOfCentralMeridian>
<gmd:standardParallel>30.0</gmd:standardParallel>
<gmd:standardParallel>45.0</gmd:standardParallel>
</gmd:MD_ProjectionParameters> </gmd:projectionParameters>
I have seen references regarding MD_CRS being struck from ISO 19115 and
perhaps indicating that projection parameters could be represented using
ISO 19111:2007 , however, apart from some Excel files in Github
repositories, I cannot find a publically available version of the schema,
nor can I find any online examples of complex projections being represented
in ISO metadata apart from simple ISO 19115 EPSG references like that above.
Although primarily in meta-discussions of metadata, I have seen references
referring
to an SC_ProjectedCRS as part of ISO 19111:2007 and others
implying that in addition to <gmd:referenceSystemIdentifier> there is a
<gmd:referenceSystemType> element that can follow it within
<gmd:referenceSystemInfo>
yet my attempts to invoke are rejected by Oxygen with my current suite of
http://www.isotc211.org/2005 validation links:
<gmi:MI_Metadata
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:gco="http://www.isotc211.org/2005/gco";

xsi:schemaLocation="http://www.isotc211.org/2005/gmi
http://www.ngdc.noaa.gov/metadata/published/xsd/schema.xsd";>
Thus I get the impression that my understanding of available resources
is dated.
Can anyone suggest a method/schema that would allow me to add the
projection parameters to my ISO metadata? Thanks!
Cheers,
Jack
