[geotk] ISO 19115-2 support

[David Neufeld]

Hi All,

We've just started exploring geotoolkit for marshalling and 
unmarshalling ISO XML, and are excited about geotookit's object model 
supporting ISO 19115.

We are also interested in the ISO 19115-2 support, and would like to 
generate ISO 19115-2 from a NetCDF file.

In the example below - marshallMetadataInstrument(), we can populate an 
instrument object using setter methods and then marshal it to ISO 19115 
XML which returns:

<gmd:MI_Instrument ...>
...
</gmd:MI_Instrument>

But it's not clear how to generate ISO 19115-2 XML from a populated 
DefaultInstrument object using the SpatialMetadata class (or whether 
this is the wrong approach entirely).

          SpatialMetadataFormat stream = SpatialMetadataFormat.STREAM;
          SpatialMetadata spatialMeta = new SpatialMetadata(stream);    
     
          Instrument instrument = 
spatialMeta.getInstanceForType(Instrument.class);
          defInstrument = new DefaultInstrument(instrument); 
//IllegalArgumentException: No such element: Citations

Any suggestions are greatly appreciated...

Thanks, Dave

    public void marshallMetadataInstrument() {

        DefaultInstrument defInstrument;
        DefaultCitation defCitation;
        DefaultIdentifier defIdentifier;
      
        defInstrument = new DefaultInstrument();             
        defCitation = new DefaultCitation();
        defIdentifier = new DefaultIdentifier();                

        //Setters
        List<Citation> citationList = new ArrayList<Citation>();
        citationList.add(defCitation);             
         
        defIdentifier.setCode("ASCAT > Advanced Scatterometer");
        defInstrument.setIdentifier(defIdentifier);

        SimpleInternationalString intStrType = new 
SimpleInternationalString("scatterometer");
        defInstrument.setType(intStrType);
        defInstrument.setCitations(citationList);
             
        SimpleInternationalString intStrDesc = new 
SimpleInternationalString("Instrument Type: scatterometer, Operational 
Mode: , Collection Type: radar.");
        defInstrument.setDescription(intStrDesc);           
       
 
        File tf = new File("C:/temp/geotkiso-instrument.xml");
        try {
          XML.marshal(defInstrument, tf); 
        } catch (Exception e) {
          e.printStackTrace();
        }               
    }
