---------------------------------------------------------------
Let's assume the webtable (bigtable paper)
{code}
url<row> content anchor
language metatag ...
http://abcd.com ... anchor:http://xyz.com <xyz dot com> ...
...
anchor:http://udanax.org <udanax homepage>
{code}
At this time, 'udanax.org' was evaporation from the world-wide-web.
Then we need to delete the 'anchor:http://udanax.org' of all rows for
transformation of url by anchor (inlink by outlink).
