It's good to see Antarctica getting some attention.

I neglected to comment on the message on the 5th, but I wanted to comment on
your proposed tags.

You are proposing ADD:code, ADD:date, ADD:text, ADD:source, and
ADD:revision.

The current wisdom is to not include these type of tags. 

The code duplicates the other OSM tags and is wrong as soon as someone
reclassifies a feature.

Date, text and revision are not documented on the wiki page so it's hard to
see what purpose they serve.

ADD:source would be better off as a source tag.

ADD:temporal and ADD:status seem unnecessary given the information is in the
seasonal and abandoned tags.

Some of the ways could really use a simplify. I'm not sure what the
appropriate value is, but there are some runs of 20 nodes in 13b a straight
line which simplify down to 2 nodes. The grounding lines seem the most prone
to this.

What tags do you plan to use on the changesets, and what size changesets are
you planning to use?
