Julien Nioche commented on NUTCH-1024:
--------------------------------------
There is a JIRA issue for 2.0 https://issues.apache.org/jira/browse/NUTCH-882,
but I'd like to do it in 1.4
We've talked about processing sitemaps on the mailing lists for some time and
now have crawler-commons to help us with the parsing. Entries in sitemaps have
some info about how frequently they are likely to be modified so it is somewhat
related to this issue.
