Ok, how far along is the Java port?

I converted one NOAA chart and opened the OSM.xml with JOSM.  Apologies if
I'm a bit new to this, I'm usually developing kernel code.  It was just a
bunch of dots representing nodes.  There were no icons for each node, which
I suspect is correct behavior.  There was no information on depth soundings
or buoy pathways.  So I'm suspecting that the converter needs enhancements
in this area?

I will start by reading up on S-57 and ISO 8211.

Thanks again,
Nick
